1 Tasks and Functions of the HMG 3010

1.1 Standard functions of the HMG 3010

The HMG 3010 portable data recorder is a hand-held unit for measurement and data acqui­sition tasks on hydraulic and pneumatic systems. Applications are primarily in maintenance
and servicing, troubleshooting and test rigs.

The HMG 3010 can monitor signals from up to ten sensors simultaneously. The unit has 5
input jacks for connecting the sensors; if necessary this number can be doubled using a
Y adapter (if more than 5 sensors are required). HYDAC ELECTRONIC provides suitable
HSI sensors (HYDAC Sensor Interface) for pressure, temperature and flow rate which are
automatically recognised and for which the measuring range and unit are set by the
HMG 3010 - the easiest choice for customers.

You also have the option of connecting SMART sensors to the HMG 3010. These represent
a sensor generation from HYDAC which can output several different measured variables.
These sensors are also automatically recognized by the HMG 3010 via HSI, and the meas­ured values including the measurement unit are shown in the display.
The HMG 3010 can render up to 32 measurement channels in total.
Depending on the sensor type, the sensor has an internal memory for the storage of re­corded measurement data on a long-term basis. In addition, depending on the sensor type,
preset parameters can be changed and stored in the internal memory as a sensor configu­ration.

Older model HYDAC sensors or commonly available sensors made by other manufacturers
can also be used. However, these sensors do not have any automatic sensor detection,
consequently the initial set-up has to be entered manually.

The operator can access all of the unit’s functions and settings by means of clearly pre­sented selection menus. The HMG 3010 has a combination keypad for entering numeric
values and text, similar to a mobile phone.

The HMG 3010 is designed in particular for recording typical measurements (pressure,
temperature, flow rate) in hydraulic and pneumatic systems. A variety of other measurement
tasks can be performed using additional inputs for voltage measurement.
For example, checking the actuation of a switching valve or plotting the characteristic curve
of a valve setpoint. In addition, it is also possible to determine differential values between
the measured values of individual sensors. One example of this is taking a flow rate meas­urement using a differential pressure orifice.

In addition to the analogue measurement inputs, the HMG 3010 features two digital inputs
(e.g. for measuring frequency or speed), thus expanding the unit’s range of potential appli­cations.
When taking measurements of rapid, dynamic machine processes, all 8 analogue input
signals can be recorded simultaneously at a rate of 0.5 ms.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 5

One special feature of the HMG 3010 is its ability to also monitor highly
dynamic processes in a machine. To achieve this, two input channels can record measured
values at a rate of 0.1 ms. This function of course requires suitable fast sensors to be used.

The most attractive feature of the HMG 3010 is its ability to record the dynamic processes of
a machine in the form of a measurement curve and render them as a graph — and, more­over, online and in real time.

The HMG 3010 is equipped with specially developed software providing for fast data collec­tion and processing. A measurement curve can consist of up to 500,000 measured values.
The HMG 3010 memory is capable of storing at least 100 such measurement curves.

In addition to enabling simple measurement curves to be recorded, the HMG 3010 also has
other functions enabling event-driven measurements to be taken and event logs to be re­corded. Various trigger options are available for triggering events.

Apart from measurement curves, the HMG 3010 can store user-specific settings (user pro­files). The main advantage of this is to enable identical measurements of various equipment
items to be repeated for the purpose of preventive maintenance. All the user has to do is
retrieve the relevant user profile from the HMG 3010’s memory.

The HMG 3010 has a 3.5" color display with graphics capabilities, which can show the
measured values either as text or as measurement curve. Individual measured values can
be displayed in a large format (7-segment format), enabling them to be read from far away.

The HMG 3010 also has a variety of user-friendly features for displaying, evaluating and
processing measured values:

• Table

• Graph

• Scaling

• Ruler

• Tracker

• Zoom

4.3 Switching on the instrument

When starting the unit up for the first time the
Welcome start-up screen appears. Select
your language using the 5-way navigation key
(select or checkmark your option by pressing
OK) and set the date and time. Select the de­sired format, and then enter the current date
and time via the keypad. Save your entries by
pressing OK, followed by Next.

The following appears in the display when
starting the unit up in normal operation:

• Manufacturer

• Designation of the instrument

• HMG version

• Date and time

• Battery charge status

The screen switches to measured value
display mode in a few seconds. If sensors
are already connected, the current meas­ured values are shown in the Current
Measured Values menu (see title bar at
top of display). To skip through the start­up screen more quickly and proceed di­rectly to the measured values menu, press
Esc or OK.

The following is listed in the measured values
screen (see screenshot): Input channel – Des­ignation – Value – Unit (of measurement)
The menu bar at the bottom of the screen
(function bar) displays the main menu and
next to that, on the right, the battery charge
status. The main menu contains the follow­ing functions which you can access using
the navigation key (arrow key) plus the OK
key.

Settings — for entering or retrieving set­ting data used for performing measure­ments
Recording — for recording a measure­ment and graphically rendering meas­urement data, e.g. as a curve

Note:
As a rule, functions which can be

selected and executed are in blue.

Functions which can’t be se­lected or altered are in Black.

Warnings appear in red
when input data is incorrect.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 12

Extras — for other functions,

plus a function for displaying the
Min/Max values.

Measuring the Min/Max values has a special
significance and is explained in more detail
below.

Apart from the current measured values, the
HMG records the minimum and maximum
values (Min/Max values) too, except when
plotting a measurement curve. The minimum
value is the lowest value to which a meas­ured variable has dropped during the time
period under consideration, the maximum
value being the highest value achieved by a
measured variable during this period. Reset­ting causes the Min/Max values to be set to
the actual measured value at the time. This
will reset all sensors.

The time period always begins when the
Min/Max values are reset. The values are
reset in the following situations:

• Switching the unit on

Note:

Even when the Min/Max values
are not shown in the display,
the HMG is nevertheless re­cording them in the back­ground.

• Selecting and activating Reset function in
the menu bar
(only if Min/Max is active)

• Connecting or removing an HSI sensor

• Altering the sensor settings

• While recording an event log

• When finishing recording

Before resetting the Min/Max values it is fre­quently necessary to determine when the
Min/Max values were last reset. To do this, go
to Extras in the function bar and then About
HMG 3010.

5 Getting Started Guide

This Getting Started Guide outlines the basic steps for conducting a simple measurement
(measured values shown in display) and plotting a measurement curve (graph of measured
values). The examples involve pressure measurement using 2 pressure transmitters with
sensor detection (HSI sensors). For a detailed description of all the settings, see Detailed
Operating Instructions.

The examples are based on the factory settings of the HMG 3010. Simply follow the
steps described here. If you don’t know the status of your HMG 3010 because there
might be more than one user in your company using the HMG, you can simply restore
the unit to its "as supplied" condition (see Manage Settings — Restore Factory Settings).

Preparation for Performing a Measurement
First charge the batteries or connect the power supply as described in Power Supply.
Two HYDAC HDA 4748-H-0400-000 pressure transmitters with automatic sensor detection
are used in the following example.

Example of a Simple Measurement Us­ing Two Pressure Transmitters

Connect the two pressure transmitters
hydraulically to your machine and connect
the two pressure transmitters using the sen­sor connector cables, e.g. to sockets
A and B of the HMG 3010.

After the HMG 3010 is switched on it jumps
to the Current Measured Values menu. The
function bar contains various functions pro­viding quick access to the three main menus:

- Settings

- Recording

- Extras

and to the display of the

- Min/Max values.

HMG 3010 Page 14

When HSI sensors with automatic sensor
detection are used, the HMG automatically
detects the measurement range and the unit
of measurement of the two connected pres­sure transmitters and shows them in the dis­play with the actual measured values. You
can also display the minimum and maximum
values for the sensors.

To hide or show the Min/Max display, press
the right arrow of the 5-way navigation key
until Min/Max is highlighted in blue and then
press the OK key. The Min/Max values of the
sensors are now also displayed. Press the
OK key again to hide the Min/Max display.

When the Min/Max values are shown, Reset
appears in the function bar, enabling you to
reset the Min/Max values as required. Select
Reset using the arrow keys (blue highlight)
and then press the OK key to reset the
Min/Max values.

The measured values can also be displayed
in a 7-segment pane. To do this, go to Set-
tings in the function bar and then press OK.
In the Settings menu, navigate to Change
display settings using the 5-way navigation
key, and then confirm with OK (see screen­shot of two-pane display on the next page).

Now select the second item, Measured
value rendering. Measured value table is
the default setting here. Press OK. A drop-

down list appears in which you navigate to 2
display panels using the arrow keys, fol-

lowed by confirming with OK. To return to
the measured value display press Esc twice.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 15

The HMG now shows the measured values
in the 7-segment display panes. Depending
on the setting, the Min/Max values are
shown in addition to the current measured
values.

The Recording menu is used for recording
measurement curves. During recording, the
measured values are recorded for a certain
period of time, stored and then shown as a
graph.

Example of Recording a Measurement
Curve:

The function bar of the Actual Measured
Values menu contains the item Recording.

Select it using the 5-way navigation key, fol­lowed by OK. In the Recording menu that
follows, select Start recording and confirm
with OK.
In the menu that follows, Start Recording,
you are shown the default settings for re­cording a measurement curve. In our exam­ple, we want to generate a Simple meas-
urement curve with two sensors at chan­nels A and B with a sampling rate of 1 ms
and a Recording time of 30 s. Then meas-

urement is to be finished.

Simple measurement curve is already set

in the menu. For the other settings, proceed
as follows:

Using the arrow keys of the 5-way navigation
key, select the third item, Sampling rate. OK
opens up a drop-down list where you select
a sampling rate of 1 ms, confirm with OK.
This takes you automatically to the Re-
cording time line. Press OK. Scroll down
the list using the arrow keys to 30 seconds,
and confirm with OK.

In the Recording option line, select End
when time has elapsed in the same man­ner.

In the Automatic operation line, select the

Deactivated option and in the Magnified
section the 5 second option.

Your display now shows the settings you
made for recording measured values (see
screenshot). To double-check your settings,
refer to the recorded data selected by you
above the function bar.

Now you can start recording by pressing

Start in the function bar + OK. A progress
bar shows you the status of your measure-

ment. The function bar offers you the option
of having the measurement curve plotted or
the actual value shown while recording.

HMG 3010 Page 17

Graphic rendering provides a faster visual

impression of the changes in the measured
values. To have the measurement curve
displayed while recording, select Graph +
OK. The screenshot on the right shows you
the curve plotted for our example.

When recording is finished, you have the
option of saving or discarding the measure­ment. To save the recording, select Save
and confirm with OK. The HMG automati­cally assigns a name and a consecutive
number, which can also be renamed by you.
In our example, accept the name suggested
by the HMG and save with OK.

You can view any stored recording again or
delete it as you like. For more information on
this, refer to Detailed Operating Instructions.

6.1 Settings Menu

Submenus of the Settings menu:

• Change settings of measurement
channels

• Change display settings

• Zero measurement channels

• Change initial setup

• Administer settings (save, load, ...)

• Administer sensor configuration

(not visible unless the configuration of a
SMART sensor has been read out, see
section 6.4.2.5)

6.1.1 Change settings of measure­ment channels

Select Change settings of measurement
channels to obtain a listing of all the chan-

nels available in the HMG (see screenshot).
There is a checkbox next to each of the
channels enabling you to switch the input
on or off (+ OK key). Activated channels
are marked by an “X”. To the right of the
checkbox is the measurement range set-
ting, the unit of measurement, and, as ap­plicable, a designation for the sensor, e.g.
"System pressure".

For connection to CAN-bus:

If the connection adapter ZBE 3010 is
plugged into D/H, the HMG 3010 automati­cally switches channel D to CAN-bus and
channel H to off.
For all the setting options for CAN-Bus, see
Section 6.5‚ CAN Functions.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 19

The various options available for channels A
to H are demonstrated here using channel A
as an example. Select the measurement
range entry on the right of the channel using
the navigation keys and press OK. This
takes you to the menu window for the se­lected channel.
To enter a designation, press OK again
and then enter it in the box using the com­bination keypad, followed by OK.
In the Mode menu you now have the option
of Automatic detection (HSI) and Manual.
The Automatic detection (HSI) option is
used for HYDAC sensors which have auto­matic sensor detection. The Manual setting
is used for adapting sensors with standard
analogue signals (e.g. 4 - 20 mA) to the
HMG.

However, there are applications for which it
is useful to enter settings manually, also in
the case of HSI sensors with sensor recogni­tion. For example, by entering settings
manually for a pressure measurement, you
can have physical variables displayed which
are proportional to the pressure, e.g. force.

Manual mode also provides the following
further settings:

• Input signal

• Upper and lower measurement range

• Unit (of measurement)

• Decimal format

As soon as you select one of these items, a
drop-down list appears or a box appears for
entering your settings.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 20

For Input signal you can choose between
HSI (HYDAC Sensor Interface) and various
standard analogue signals in the drop-down
list (using the arrow keys). To set the Lower
and Upper measurement range, enter the
relevant limits via the combination keypad.

A drop-down list is also provided for
selecting the Unit (of measurement). You
also have the option of defining your own
unit with other (top line of the drop-down
list). The cursor then jumps to the input
box and a small triangular arrow appears
as the insertion point. Enter the new unit
using the combination keypad, e.g. ”kPa”
for kilopascal.

To enter additional characters, move the
triangle insertion point to the desired posi­tion and enter the characters. Confirm your
entry with OK so that your unit of meas­urement is stored.

Decimal format: Here you can specify how
many decimal places are to be used when
recording and displaying the measured val­ues.

In addition to the settings described above,
Channel B has two further measurement
options. In the Mode drop-down menu you
now also have the menu options Pressure

difference dP and Orifice measurement
Q=f(dP). With Pressure difference dP the

HMG 3010 gives you the opportunity to dis­play the difference in pressure between
channel A – channel B with a very high de­gree of accuracy. This can be used, for ex­ample, to determine if a filter is clogged, by
measuring the pressure differential.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 21

The function Orifice measurement
Q=f(dP) enables you to carry out a flow
rate measurement by measuring the differ­ential pressure at a flow rate measurement
orifice (e.g. HYDAC EVS 1000).
For both these modes HYDAC HSI pres­sure transmitters with the same measure­ment range must be connected to channel
A and channel B. The differential meas­urement range is produced automatically,
being ± 10% of the measurement range of
the pressure transmitters connected. The
accuracy of the HSI pressure transmitters
is ≤ ± 0.5 % FS.
This means that one 100 bar pressure
transmitter might measure 50 bar pressure
as being 49.5 bar, and another might
measure it as 50.5 bar. These pressure
transmitter errors can be compensated for
by recording a correction curve.
After correctly recording a curve, the accu­racy for differential measurement is ≤±0.1%
of the differential measurement range.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 22

Example:
For both 100 bar pressure transmitters there is a differential measurement range of

-10 – +10 bar, in other words a measurement margin of 20 bar. The accuracy of ≤ ± 0.1%
refers to this measurement margin. The pressure differential can therefore be measured with
an accuracy of ≤ ± 0.02 bar.

To measure a pressure difference, select
the item Pressure differential dP. Then you
find a menu point Organise curves. Here
you can plot up to 3 curves for 3 pressure
transmitter pairs. If a curve for a pressure
transmitter combination already exists, you
can quit the menu again by selecting Back
or the Esc key. The HMG 3010 automatically
selects the appropriate curve. If you quit the
menu and the HMG 3010 detects that no
curve exists for this combination, you will get
the message shown on the right. You can
now, with less accuracy, measure the differ­ential or you call the menu item again to re­cord a new curve under Organise curves.

Once Organise curves is selected, a screen
appears which allows you to record a new
curve, or you see information on curves
which already exist. At this point you can
also delete existing curves if they are no
longer required. If curve 1 already exists,
navigate to this field and press the OK key.
You can now, for example, select Character­istic curve 2, Not available and then record
a curve. To record the curve you must con­nect both pressure transmitters to the
HMG 3010 at channel A and channel B.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 23

When doing this, identify which pressure
transmitter has been connected to channel A
and which to channel B, since the pressure
transmitters must be re-connected in the
same way later when taking measurements.

Connect the pressure transmitter
hydraulically so that the two instruments are
subjected to the same pressure. The ideal
for recording curves is connecting to a test
rig on which you can increase the pressure
slowly from 0 bar to the full measurement
range of the pressure transmitter and back
again.
However, the minimum requirement is to
record the curves/measured values in the
pressure range in which the differential
measurement is to take place later.

In the example above (to measure the filter
contamination level) both pressure
transmitters might be fitted to the inlet side of
the filter, e.g. using T-fittings and then, with
the machine running, the curve could be re­corded.
When these pre-conditions are in place,
select Record characteristic curve. This
brings up a display showing 0 to 100% of the
whole measurement range. If you increase
the pressure you will see from the blue bar
that measured values are being recorded in
this pressure range.
If the measured values remain under the red
line, this means that not enough values have
been recorded in this range. To achieve
maximum accuracy for differential
measurement, the recorded measured val­ues should at least be in the area between
the red and the green line. After this, select
Stop recording and you can quit the menu.
The curve is now automatically taken into
account for the differential measurement
using these two pressure transmitters.

In order to measure the flow rate using a
differential pressure measurement at a flow
rate orifice, select the item Orifice meas-
urement Q=f(dP). Then select the number
of decimal places and the unit (of measure­ment).
A flow rate orifice is supplied with information
showing the correlation between pressure
differential and flow rate. For example, on a
HYDAC EVS 1000 it says: calibration factor

4.87 bar at 350 l/min. Enter these values
under the flow rate and pressure.

Here again the menu Organise curves appears, (for a function description and handling,
see Pressure differential dP above). Curve recording can be carried out exactly as de­scribed above.

If you are using a HYDAC EVS 1000 flow rate measurement orifice, you can also use this to
record curves. On the EVS 1000 there are 2 pressure ports before the orifice (ports 1 and 2)
and one after (port 3).

To make a recording, connect the pressure transmitter from channel A to port 1, and the one
from channel B to port 2. To start measurement you need only then to change the pressure
transmitter from port 2 to port 3.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 25

Input channels I and J are for digital (not
analogue) signals. As the input signal you
can choose between Count pulses and
Frequency signal. There are many possi­bilities for this, e.g. speed sensors, proximity
switches, pulse generators, flow rate meas­uring instruments with a frequency signal,
HYDAC HDS 1000, to name only a few. As
in the case of the analogue sensor inputs,
settings can be manually entered for the
input signal, unit of measurement and deci­mal format.

In addition to these settings, a factor has
to be entered which is required for con­version to the desired unit of measure­ment.

Another special feature is that the Upper
measurem. range must be input. Frequen­cies of up to 30000 Hz can be measured on
channels I and J, consequently a scale from
0 to 30000 is possible in the graphical dis­play. If, for example, you record a speed of
up to 1450 rpm, an awkward Y-axis scale will
result in the graph. If you enter "1500" as the
Upper measurement range for this speed
measurement, for example, the Y-axis in the
graph will be scaled from 0 to 1500 rpm.

In this case the reason for inputting the upper measurement range is just a means of limiting
the scale of the Y-axis in the graphical display. You should set this value as close as possible
to that of the expected measured value in order to get the best possible graphical display.
If there are measured values higher than the upper measurement range, these are not lost.
The scale of the Y-axis can be changed again in the graph at any time later on.

Caution!

The measurement range of the frequency entries is 1 Hz to 30000 Hz. If, for example, the
rpm of a motor is recorded and this motor stops abruptly, the last rpm can still show in the
display for up to 2 seconds, depending on the measurement system, before 0 is displayed.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 26

Examples of frequency measurements:

1) You would like to measure a frequency up
to 1000 Hz. Frequencies are recorded by the
HMG per minute. Enter "60" as the Factor to
display the frequency in Hz, enter "1000" for
the Upper measurem. range to scale the Y­axis from 0 to 1000 in the graphical display.

2) You would like to measure the speed of a
machine from 0 to 2900 rpm, the speed sen­sor supplies 2 pulses per revolution. Enter
"2" as the Factor and "3000" as the Upper
measurem. range. The display is then in
revolutions per minute; for the graphical dis­play, the Y-axis is scaled from 0 to 3000.

3) A flow rate measurement transmitter in a
measurement range up to 450 l/min with a
frequency output supplies 8 pulses per litre.
Enter "8" as the Factor and "500" as the Up-
per measurem. range. The display is then in
l/min; for the graphical display, the Y-axis is
scaled from 0 to 500.

Examples of count pulses:

1) The switching output of a proximity switch
on a conveyor belt is connected to the fre­quency input of the HMG 3010. Enter "1" as
the Factor and the expected maximum
quantity to be counted (maximum 30000) as
the Upper measurem. range.

2) A gear flow meter supplies 250 pulses per
liter. Enter "250" as the Factor and as the
Upper measurement range, the maximum
no. of litres expected (maximum 30000).

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 27

If you have selected counter pulses as the
input signal, and have returned to the normal
measurement value display, you will find on
the far right of the function bar a symbol, as
shown in the screenshot. The counter is cur­rently stopped. If you select the symbol us­ing the arrow key and confirm with OK, the
counter is reset and will start again. To stop
it, select the symbol again using the arrow
keys and confirm again with OK.

In addition to the input channels (channels A
to channel J) there are also the virtual chan­nels Channel K and Channel L available.
These two channels can be used to display a
differential between 2 input channels, or to
calculate a power.

When setting to Differential the HMG 3010
calculates for channel K the difference be­tween channel A/channel B and for channel L
the difference between channel C/channel D.
To measure the differential, sensors with the
same measurement range, unit (of meas­urement) and number of decimal places must
be used on the input channels. These pa­rameters are then automatically adapted to
channel K or L, i.e. no further settings are
necessary.

If you would like to measure Power (P*Q),
via channel K, the pressure must be meas­ured at channel A and the flow rate must be
measured at channel B. To measure the
power via channel L you have to measure the
pressure at channel C and the flow rate at
channel D. You can then select kW, PS or
hp as the unit (of measurement).
Entering the upper measurement range
merely limits the scale of the Y-axis in the
graphical display.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 28

You should set this value as close as possi­ble to that of the expected power value in
order to get the best possible graphical dis­play. If there are measured values which are
higher than the upper measurement range,
these are not lost. The scale of the Y-axis
can be changed again in the graph at any
time later on.

This brings you back again to the display
shown on the right.
is shown at channel K, and the difference at
channel L.

If you have made an invalid setting, or you
have connected 2 sensors with different
measurement ranges for the differential, for
example, the relevant calculated channel is
deactivated. In the example, a pressure
transmitter with measurement range of 0-100
bar has been connected to channel C and a
pressure transmitter with a measurement
range of 0-250 bar has been connected to
channel D.
Therefore channel L would be automatically
deactivated.

6.1.2 Changing Display Settings

The next submenu of the Change Display
Settings item enables you to make settings

affecting the display and rendering of meas­ured values and the display size in keeping
with your measurement task. Select the item
using the arrow keys, followed by OK.

When selecting Measured value dis-
play, a drop-down list appears ena­bling you to choose the rendering
speed:

• Fast

• Medium

• Slow

• Delayed

Make your selection, followed by OK.

Note!

The settings for displaying the measured
value has no impact on the measurement
itself. It is just to make the display easier
to read, e.g. during pulsations.

For Measured value rendering you can
choose between the measured value table
and various 7-segment display formats (1

display panel, 2 display panels, ..., Set
automatically).

When selecting Set automatically, the HMG
automatically searches for the optimal ren­dering. When two sensors are connected
and activated, the display looks like this
screenshot.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 30

The screenshots on the right show the
measured values of four sensors when the
2 display panels option is selected and the
Min/Max display is activated. Consequently,
the display only shows the measured values
of two sensors at a time. Use the arrow keys
(▲) and (▼) to see the measured values of
the other two sensors.

In order to display the measured values of
4 sensors simultaneously, you need to se­lect the 2x2 display panels option (cf.
screenshot).

In the third line of the Display settings
menu there is a Yes/No option next to Show
progress bar. When Yes is selected, the
progress bar is also shown in the measured
value display. The appearance of the display
may vary according to what settings have
been made for rendering the measured val­ues.

The overall width of the particular progress
bar corresponds to 0 ... 100% of the meas­urement range. The progress bar shows the
position of the actual measured value in the
overall measurement range. Showing the
Min/Max values causes the display to be
altered. The current measured value is now
shown by a dot and the length of the pro­gress bar shows the range from Min to Max.

No switches off the progress bar.
Back takes you back to the Settings menu.

6.1.3 Zeroing Measurement Channels

You can re-zero the measurement channels
in the Settings menu. This function is used to
mask out backpressure buildups present in
the system. For example, if a pressure of 3
bar is present at a pressure transmitter de­spite the fact that the system has been
switched off, this value can be used as the
new zero point for display purposes.

Re-zeroing can be done at any point
throughout the measurement range of a
measurement channel.

In the Settings menu, select Zero meas-

urement channels, and then confirm with
OK. The screen on the right appears. You

are now prompted to select a measurement
channel. Select the channel (checkbox)
which you would like to zero using the arrow
keys, and then confirm with OK. Then select
Set followed by OK — you have zeroed the
channel. You can delete the changed zero
point by pressing Delete.

All measurement channels which have
been re-zeroed are indicated by an arrow
in front of their designation for safety
reasons (see screenshot).

Caution!

A high pressure may still be present in a
measurement channel marked by an arrow
even though the display shows 0 bar.

When removing a sensor or other system
components make sure the system has been

depressurized first.

Failure to do so may result in serious in­jury or death!

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 32

Switching the HMG unit or measurement
channels OFF/ON doesn't automatically de­lete the newly set zero point. The following
message is shown when switching the HMG
off and then back on:

"Some channels have a zero offset."
Press OK to retain the zero offset or
"Esc" to delete it.

To determine the extent of a zero offset
which has been set, go to the Settings menu
(OK) and select Zero measurement chan-
nels (OK). This brings up a list of all the
channels which are active. Channels with a
zero point adjustment are checkmarked.
The value of the zero offset is shown on the
right.

Any zero offset is also shown in the meas­urement channel list by way of a small arrow
in front of the measurement range. To find it,
go to the Settings menu, then Change Set­tings of Measurement Channel (OK).

There is one exception where the zero offset
is automatically deleted. This happens when
a sensor is connected to the channel and
this sensor has a different measurement
range to the one for which the zero offset
was set. This means that the zero offset is
not retained unless the lower and upper
measurement limit, the number of decimal
places, and the unit of measurement of the
newly connected sensor are identical.

When the zero offset is automatically de­leted, a message to this effect appears in the
display for two seconds.

6.1.4 Changing the Initial Setup

Change initial setup is a submenu of the
Settings menu.

To make changes to the initial setup, press
OK. You can now change the following
items:

Language

You can choose between German, English
and French.

- Select your language using the arrow
keys, followed by OK.

Setting/Correcting the Date and Time
Various format options are offered depend­ing on the language selected and the asso­ciated regional formatting applicable to the
date and time. Make your selection, followed
by OK. Then enter the actual date and/or
time of day using the number pad.

- Save by pressing OK.

Automatic Measurement Units

This subitem refers only to HSI sensors with
automatic sensor detection. When the sen­sors are connected, the unit of measurement
of the sensor is read out and automatically
adopted.

If, for example, you want all pressure
transmitters with automatic sensor detec­tion to show psi readings, you can make
this setting here.
For a connected 0 ... 100 bar pressure
transmitter, the HMG then shows the meas­ured values in a measurement range of 0 ...
1450 psi, i.e. the measurement range and
the unit of measurement are automatically
converted.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 34

Note!

Automatic conversion of measured values
to the selected unit of measurement will not
work unless Automatic detection (HSI)
mode is selected under Settings – Meas-
urement Channel Settings.

Select the unit of measurement to be
changed, followed by OK. Select the new
unit of measurement desired from the drop­down list by pressing OK.

In the list of measurement channels, the
measurement range for this channel is now
shown in 0 ... 1450 psi instead of in 0 ... 100
bar for example.

In the current measured values display
the measured values show psi readings
(listed after the channel or sensor designa­tion).

6.1.5 Administer settings

(save, load, ...)

All of the measurement channel settings
made by you in the HMG for the last meas­urement can be saved and then reloaded
later in order to be able to repeat the same
measurement periodically, for example.

You can also delete individual stored set­tings or restore the factory settings.

Select Administer settings (save, load, ...),
press OK, and now proceed to the Adminis-
ter Settings menu with its four submenus
(see screenshot).

When you confirm Save current settings
with OK, you see the name of the setting
saved last, or No Name if nothing was
saved. Confirm with OK, and you are shown
a list of all the saved settings and/or the op­tion of entering a new name. Select New
Name and enter a name using the combina­tion keypad.
Press OK x 2 to save the new name and to
return to the Administer Settings menu.
The HMG automatically assigns a consecu­tive number, which can also be changed by
you.
The HMG automatically assigns the next
highest unused consecutive number, which
is always unique. Any gaps in the list of
numbers are not filled.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 37

In the submenus Load stored settings or
Delete stored settings, you are shown a list
of all the saved settings from which you can
Load or Delete individual settings.

Navigate to a setting using the arrow keys
and highlight using OK. The item "activated"
jumps into the function bar, enabling you to
accordingly Load or Delete the setting.

You can restore your HMG to the original
factory settings by selecting Restore factory
settings (see right).

Confirm Restore factory settings with OK
and the menu following offers you two op­tions. Select the required function (check­box) followed by OK and execute the option
via the Execute command in the function
bar.

6.2 Recording Menu

Here the HMG enables you to perform a
measurement for a specific period of time
and save it. This recording can be rendered
as a graph or a table. To do this, proceed as
follows: To access the recording menu, go to
the Current Measured Values menu, then
select Recording in the function bar at the
bottom. In the Recording menu that follows,
select Start recording, View recording or
Delete recordings, using navigation keys
and confirm with OK.

6.2.1 Starting a Recording

The Start recording option takes you to a
menu which lists the individual measurement
parameters which can be set for making a
recording. When selecting the first item, Re-
cording, a drop-down list appears in which
you can choose between Simple measure-

ment curve, Measurement curve with
trigger or Event log. Select appropriate

recording option followed by OK.
Select Simple measurement curve to make
additional parameter settings:

Measurement channels
The active measurement channels are
shown here. Confirm with OK. You now
proceed to the Change Settings of
Measurement Channels menu. All of the
settings you can make here are described
in detail in the Changing the Settings of

the Measurement Channels section of
Settings Menu. Before starting your re-

cording you can now also decide whether
you want to switch off individual channels
(X = "off").

Caution!

Don't forget to reactivate the
measurement channels after com­pleting your measurement, assum­ing they are still needed.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 39

Sampling rate

This item enables you to set the rate at
which the HMG reads a measured value
from the sensors and saves it in the internal
memory. A measurement curve may com­prise up to 500,000 measured values. Se­lecting 1 ms, for example, means that 1000
measured values per second are taken and
saved for each connected measurement
channel.

Use the arrow keys ( ▲ ) and ( ▼ ) to scroll
through the various settings for the sampling
rate. At the bottom of the display you see
information on the resulting recorded data
(number of data records and memory us­age). If you select an invalid setting, mean­ing that the sampling rate selected by you
would exceed the 500,000 maximum, you
are shown a message in lieu of the recorded
data describing the invalid setting made by
you.

The sampling rate selected depends primar­ily on the measurement task at hand. A
sampling rate of 1 s is probably sufficient for
monitoring the temperature in a hydraulic
tank, as temperature changes generally pro­gress slowly. If, however, you want to track
extremely rapid system-induced pressure
surges, which generally occur in the milli­second range, you have to work with a sam­pling rate of 1 ms or less.

HYDAC HSI pressure transmitters with
automatic sensor detection are capable of
tracking rectangular pressure pulses (theo­retically occurring in a time of 0 s) less than

0.5 ms apart.

This means that simply setting a sampling
rate of 0.1 ms is not sufficient to capture
pressure surges occurring faster than 0.5 ms
apart. A suitable dynamic pressure transmit­ter also has to be used.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 40

The sampling rate which can be set is also
dependent on the active measurement
channels:

• 0.1 ms max. 2 analogue input channels

• 0.2 ms max. 4 analogue input channels

• 0.5 ms all 10 input channels

• 1.0 ms for SMART sensors

Recording time
A drop-down list appears when this item is
selected. Using the arrow keys (▲) and (▼)
you can select a recording time of between 1
second and 24 hours, followed by OK.

Similar to when changing the Sampling rate,
information is shown at the bottom of the
display pertaining to the recorded data show­ing you the result of your setting.

Recording option
The options available here are End when

time has elapsed and Record continu­ously until terminated.

End when time has elapsed means that

recording is discontinued when the time en­tered in Recording time has elapsed.

Record continuously until terminated
means that the oldest measured values to be
deleted when new measured values are
added once the time entered in Recording

time has elapsed. The time period entered in
Recording time remains as the "past" in

relation to the actual time in the measured
value memory until the Stop command is
given (Stop + OK or actuate the Esc key).

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 41

Automatic mode

In this menu point, you define whether the
recording (using the settings previously set)
is to be started just once or at regular inter­vals.

Deactivated means that the recording is
started as predefined, and is ended once the
stop condition occurs and is saved.

Activated means that once the stop condi­tion occurs, the current recording is ended
and saved, and a new recording is started
immediately with the same conditions. When
the stop condition occurs again, it is saved
under a consecutive number.
This continues until the (automatic) recording
is ended with Autostop and subsequent
stop condition or the memory is full.

The automatic operation reverts automati­cally to "deactivated" each time a recording
is stopped, and must be "activated" again as
required.

Zoomed area

With the "zoomed area", an additional dis­play area can be created during the re­cording in the graphic mode.
I.e. when setting Zoom the x-axis is scaled
to the time span preset in this menu point (5
seconds / 10 seconds).
(The setting options for the zoomed area are
dependent on the preset sampling rate and
the specified recording time.)

Example of recording a Simple Measure-

ment Curve

The settings made for the example shown on
the right mean that the measured values of
channels A and B are recorded with a sam­pling rate of 1 ms (i.e. 1000 measured val­ues per second, referred to as data records
under recorded data), and that recording is
automatically discontinued after 10 seconds.
You see the following brief summary under
Recorded data:
10,000 records each consisting of 2 values (1 x
channel A, 1 x channel B), memory usage:
41 kB.

Now you can either start or cancel (or Esc)
the recording from the function bar. The fol­lowing appears in the display (see right) after
starting a recording. You see a list showing
the start time, date & time, the time elapsed,
and the number of data records recorded. A
progress bar shows you the status of your
recording.

The function bar offers you the option of hav­ing the measurement curve plotted (graph)
or the current measured values displayed.
Graphic rendering provides a faster visual
impression of the changes in the measured
values. To have the measurement curve plot­ted while recording, select Graph + OK. The
screenshot at the right shows you what the
plotted measurement curve might look like.

Note

When plotting a measurement curve, re­cording of the Min/Max values is switched off
as all the measured values are rendered in
the curve for the period under consideration.

Recording can be discontinued at any time
by selecting Stop or pressing the Esc key.
When recording is concluded, the measure­ment must be saved or discarded.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 43

Before doing this, you can have the meas­urement shown again as a curve (Graph +
OK) or as a measured value table
(Table + OK).

When doing this, other tools are offered for
analyzing the chart or table. For more infor­mation on how you can retrieve recordings
and view them as a curve or table, please
refer to Viewing Recordings.

Back/Esc enables you to return to the

Simple Curve Recording – Status screen.

To save the recording, select Save and con­firm with OK. The HMG automatically as­signs a name and a consecutive number,
both of which can be subsequently changed
by you. Select the appropriate item + OK
and make your entries using the combination
keypad.

The Comment item enables you to enter
text, e.g. a description indicating the opera­tional status of the unit or facility while the
recording was being made.

To save the recording, select Save and con­firm with OK. The HMG saves the measure­ment settings together with each recording
so that a detailed measurement log is cre­ated.

Generally speaking, the following applies:

Each measurement is given a number.
The HMG automatically assigns the next
highest unused consecutive number, which
is always unique. Any gaps in the list of
numbers are not filled.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 44

Measurement Curve with Trigger

Measurement curve with trigger is another
recording option. Trigger means that a
measurement curve can be started auto­matically when one or more specific events
occur. Examples of events are when a limit is
exceeded or not achieved, or when a meas­urement departs from a measurement win­dow.

When selecting Measurement curve with
trigger, you see other parameters which can
be set in addition to the setting parameters
available for Simple measurement curve
(Measurement channels, Sampling rate, and
Recording time, Automatic operation and
Zoomed area). The additional settings are
Trigger settings and Pre/Post trigger.

Select Trigger setting + OK. In the menu
which follows you can specify up to 4 differ­ent trigger events (event 1 to 4). To activate
an event, select the relevant box by pressing
OK so that a checkmark appears. The event
used last is shown next to the checkbox.
(What appears in the display varies accord­ing to the event used last.) Use the arrow
keys to navigate to the right to the event box,
and confirm with OK.

In Trigger event ..., confirm with OK. The
following list of trigger events is displayed:

• Actuation of button/key

• External signal change

• Specific value

• Leaving measurement window

• Timed

Select the appropriate option for your meas­urement task.

Edition 11/2011 - V04 R01 Part No.: 669855

Event: Actuation of button/key

This setting is designed to trigger a meas­urement when a button is specifically ac­tuated. After starting the recording, you
can trigger measurement by selecting

Trigger in the function bar (+ OK).

Event: External signal change

An external signal change means that you
apply a direct current signal to one of the
frequency inputs (I or J), e.g. via a button
(NC or NO contact). A measurement can
then be started when the voltage is switched
on via an NO contact (rising signal edge)
or NC contact (falling signal edge).

In the settings menu (see screenshot), you
specify the trigger input under Input. Only
the two digital inputs I and J are available
here. Next you set the Slope to rising or

falling and confirm with OK.

Event: Specific value

Use the trigger event Specific value to lo­cate pressure peaks or pressure troughs in a
machine. Pressure peaks always occur in a
rising direction (measured value increases),
whereas pressure troughs occur in a falling
direction (measured value drops). First de­termine the measurement channel and sub­channel for which you wish to set the trigger,
then enter the measured value (via the nu­merical keypad) at which you want to trigger
a recording. Finally, select the direction
(From below or From above).

Note:
Sub-channel setting only required for SMART sen­sors (see Section 6.4) and CAN function (see Sec­tion 6.5).

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 46

Event: Leaving measurement window

This trigger event is very similar to Specific
value. You can specify a Lower Limit and

an Upper Limit. The trigger is activated
when the measured value enters the meas­urement window. However, recording is not
started until the measured value leaves the
measurement window in a rising or falling
direction.

Note:
Sub-channel setting only required for SMART sen­sors (see Section 6.4) and CAN function (see Sec­tion 6.5).

Event: Timed

The event setting using a time function
(Timed) is useful for measurements which
are to be repeated at specific intervals. In the
Settings menu you can specify the number
of Repetitions (max. 30,000), the Interval
and the Starting time. In the Start item you
can specify whether this event is to be acti­vated immediately (Start immediately) or
not until after a certain Start date and Start
time.

In the

– Event: Timed –

example shown on the right, a measurement
is started 10 times every 30 minutes. The
trigger becomes active for the first time on 21
October 2006 at 14:20.

Up to 4 events can be specified for recording
triggered measurements. After making each
of the settings, return to the Trigger Set-
tings menu via Back. The menu now pro­vides an overview of all the events and set­tings for you to check.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 47

Linking Events

You also have the option of linking events.
Without linking, each of the four events acts
alone and independently as a trigger for a
measurement recording.

In the line Joint events (options shown to
the right) a drop-down list opens containing
the linked event options. In the example, the
linking of Events 1 and 2 (shown on the left
by a circuit diagram symbol) means that re­cording is EITHER triggered by the simulta­neous occurrence of events 1 and 2 (the
measured value in channel A drops to 5.00
bar, with the measured value in channel B
leaving the window of 4.00 to 6.00 bar at the
same time)
OR a voltage signal (falling signal edge) is
detected at trigger input J,
OR a key or button is actuated.

Other event linking options are shown in the
drop-down list. It should be borne in mind
that events are always listed in descending
order, otherwise you have to re-sort the
events.

In the 1 and 2 and 3 and 4 option, all events
have to occur simultaneously in order for a
recording to be triggered. By contrast the last
option
– 1 and 2 & 3 and 4 –
provides three variants:

A triggered recording is initiated when
a) 1 and 2 coincide or

b) 3 and 4 coincide or

c) all, i.e. 1 and 2 and 3 and 4, occur simul-

taneously.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 48

The next setting parameter for recording a
triggered measurement curve is Pre/post
trigger. After starting a triggered measure­ment curve the HMG begins to record the
measured values for the recording time set
(e.g. 30 seconds). If the trigger event does
not occur during this time, the oldest meas­ured values are replaced with new measured
values in the measured value memory. This
means that you always have the set re­cording time as the "past" in the measured
value memory.

The Pre/post trigger option enables you to
specify how much of this "past" is to remain
in memory when the event occurs and how
much "future" you would like to record after
the event.

A Pre/post trigger setting of 50 / 50%
means that for a recording time of 30 s the
"oldest 15 s" are discarded, 15 s remain be­fore the occurrence of the event, and re­cording is done for another 15 s after the
trigger event occurs.

With Automatic mode you define whether
you wish to make just one recording (Deac-
tivated) or whether, after recording one
measurement curve, another curve is to be
recorded using the same settings (Acti-

vated). For a Simple triggered measure-
ment, select the Deactivated automatic

measurement option.

Zoomed area

With the "zoomed area", an additional dis­play area can be created during the re­cording in the graphic mode.
In other words, with the Magnifier setting,
the x-axis is scaled to the time span preset in
this menu point (5 seconds / 10 seconds).
(The setting options for the zoomed area are
dependent on the preset sampling rate and
the specified recording time.)

Example of an Automatically Triggered
Measurement

The following occur in a hydraulic press from
time to time: defective components, ruptured
hoses or cracked cylinders. You suspect
there may be extremely high pressure peak­ing in three hydraulic circuits and want to
monitor the press for pressure surges for an
extended period of time.

To do this, you make the following settings:

• Recording:

Measurement curve with trigger

• Channels: A, B, C

• Sampling rate: 1 ms

• Recording time: 30 seconds

Trigger settings:

• Event 1: channel A increases to 180 bar

• Event 2: channel B increases to 230 bar

• Event 3: channel C increases to 280 bar

(Each of these pressures is 50 bar higher
than is normally allowed.)

• Pre/post trigger: 80 / 20%

(You select this option because you are
interested in knowing what happened in
the other pressure circuits before the trig­ger was actuated and you want to record
the pressure curve somewhat longer after
the trigger event.)

• Automatic measurement: Activated

When actuating Start (+ OK) in the function
bar, in the next screen you are prompted for
a name and number for the measurement.
The measurement is then stored under this
name with a consecutive number after
every trigger event. You also have the option
of entering a comment, e.g. the operating
condition of the machine.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 50

As soon as you confirm this with OK, meas­urement is activated, resulting in the screen
shown on the left. Selecting Graph means a
measurement curve is plotted and displayed
(cf. top screenshot), selecting Measured
values takes you to the normal measured
values screen (cf. bottom screenshot). If you
like, you can switch back and forth between
the Status, Graph and Measured values
screens.

You can manually end the recording cur­rently in progress at any time by selecting
Stop. This cancels the current measurement
and activates a new measurement automati­cally. To end automatic measurement, select
Autostop followed by OK.

After ending automatic measurement the
result obtained is a series of measurements,
which can be viewed as a list via View re-
cording. To do this, select View recording
in the Recording menu; you are now shown
all of the measurement curves just recorded.
Select one of the recordings using the arrow
keys. A short overview of the recorded data
appears above the function bar for the re­cording selected.

The recording can be displayed as a graph
or a table via the relevant options in the func­tion bar. For more details on this, please
refer to section Viewing Recordings.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 51

Event Log

The Event Log option enables you to store
measured values as a table. A line in the
table contains the current measured value, in
addition to the Min and Max value of each
active channel. The trigger settings enable
you to specify which event is to create a new
line in the event log once the measurement
has been started (e.g. Actuation of but­ton/key, Specific value). As soon as a new
measured value line is saved, the Min and
Max values are always automatically reset.
Similar to the recording option Measure-
ment curve with trigger, in automatic
measurement you can also choose whether
you would like to make just one recording or
whether an event log is to be recorded again
afterwards using the same settings.

Example of an Event Log
In order to gauge the quality of a stamping
operation, the stamping machine is to be
monitored for two hours. Proper stamping
requires a die closing pressure of between
127 bar and 132 bar. In this case, only the
maximum pressure value in each cycle is of
interest. Measurement is done using a pres­sure transmitter at channel A.

To make the recording, proceed as follows:

• From Start recording menu, Recording

item: select Event log.

• For our example, activate only chan-

nel A.

• For Trigger settings: select Specific

value for event 1, channel A, measured
value: 5 bar, and Measured value fal­ling.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 52

• In order to also manually generate a

measured value line, set a second event
to Actuation of button/key.

• Automatic measurement: Deactivated

When measurement starts, a new menu win­dow Event Log Recording — Status opens,
enabling you to track the measurement on
the basis of the settings. Data is recorded
only when an event occurs.
The sampling rate for the event log is auto­matically determined by the HMG in keeping
with the number of active measurement
channels:

• 0.1 ms max. 2 analogue input channels

• 0.2 ms max. 4 analogue input channels

• 0.5 ms all 10 input channels

• 1.0 ms for SMART sensors

For the above example this means that the
stamping press is switched on, the pressure
reaches 131 bar and drops back to 0 bar.
When reaching 5 bar in the falling direction,
a measured value line is generated and the
Min/Max values are reset. The last Max
value is retained in the measured value line.
A die closing pressure of 129 bar is reached
in the next cycle. This value is also written to
a new line as the pressure drops to 5 bar.

The function bar offers you the option of hav­ing the current measured values displayed
(Measured Values) or a Table shown.

The Table option will list the data records of
each individual event line by line. Apart
from the date and time of the respective re­cording, the trigger event and the Min and
Max values for the active sensors are
shown. The most recent data record is
shown in the bottom line of the table.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 53

Using the arrow keys of the 5-way navkey,
you can select the arrows next to the scroll
bar. After confirming with OK, you can scroll
in the table up/down and left/right. After con­firming with OK, you can scroll up/down and
left/right in the table.
A single arrow means scrolling line by
line, a double arrow means screen by
screen, and means "jump to the begin­ning or end of the table".

You can end the event log recording with
Stop in the function bar. In the next menu
you are shown an overview of the event log
and are prompted to Save your recording or
Discard it (function bar).

Before doing this, the measurement can be
shown again as a curve (Graph + OK) or
table (Table + OK). Other tools are also
available. For more information, please refer
to the next section Viewing Recordings. It
provides a detailed description of the options
available and how to use the tools and other
features for analyzing each saved recording,
whether as a table or a graph.

To save the recording, select Save and con­firm with OK. The HMG automatically as­signs a name and a consecutive number,
both of which can be subsequently changed
by you. Select the appropriate item + OK
and make your entries using the combination
keypad.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 54

The Comment item enables you to enter a
text, e.g. a description indicating the opera­tional status of the unit or system while the
recording was being made. The HMG saves
the measurement settings together with each
recording so that a detailed measurement
log is created.

Note:
For the same example, if you select automatic measurement Activated and start the meas­urement with Start, you are asked to allocate a Name and a Number to the measurement.
The measurement is then stored under this name with the next consecutive number. In the
function bar on the screen you also see the Autostop function. The measurement currently
running can be ended by selecting Stop. This measurement will then be saved and a new
measurement will start automatically. To end automatic measurement, select Autostop fol­lowed by OK. The measurement that was just running is resumed and can be ended again
by selecting Stop.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 55

Start-Stop Measurement

The Start-Stop Measurement option allows
you to start a recording when triggered by a
defined condition and to stop it again when
triggered by a second defined condition.
If the stop condition does not occur within
the pre-set recording time, then the re­cording will stop after the specified time has
elapsed.

Example of a Start-Stop Measurement:

Under Trigger 1 (Start) and Trigger 2
(Stop) select the relevant start and stop

condition and confirm with OK.

Under Recording time, define the time at
which the measurement must stop automati­cally if the Trigger-Condition 2 (Stop) has not
occurred by then.

With Automatic mode you define whether
you wish to make just one measurement
(Deactivated) or whether, after recording
one measurement curve, another curve is to
be recorded using the same settings (Acti-

vated).

Zoomed area

With the "zoomed area", an additional dis­play area can be created during the re­cording in the graphic mode.
In other words, with the Magnifier setting,
the x-axis is scaled to the time span preset in
this menu point (5 seconds / 10 seconds /
...).
(The setting options for the zoomed area are
dependent on the preset sampling rate and
the specified recording time.)

6.2.2 Viewing Recordings

The View recording item in the Recording
menu will display a list of the recordings
stored in the HMG. Use the arrow keys to
select the measurement you wish to view.
The selected recording is indicated by an
arrowhead and is blue-highlighted. The as­sociated recorded data appears above the
function bar.

Before selecting a measurement, this list can
be sorted according to

• Name

• Number

• Recording started

and in ascending (▲) or descending order
(▼) in each case.

Hit Esc to change from the selection list to
the menu in the next level up. The arrow key
(▲) enables you to access the header row.
The list can be sorted accordingly by press­ing OK. To do this, select Name, Number or
Recording started in the header row. To sort
in ascending or descending order, click in
the relevant column header with OK (press­ing OK more than once will reverse the sort­ing order). An arrow next to the column
header indicates whether sorting is in as­cending (▲) or descending (▼) order. To
return to the selection list, press (▼) + OK.

In the list of the stored recordings, select a
measurement followed by OK. You are now
in the function bar and can now decide
whether you want to view the measurement
as a Graph or a Table. This applies to
measurement curves and event logs.

.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 57

Graph

A measurement can also be rendered as a
measurement curve. To do this, select
Graph + OK in the function bar. The screen­shot on the right shows what appears next in
your display. The measurement is scaled
throughout the entire time range (x-axis)
and measurement range (y-axis). Above
the y-axis you can see which channel is cur­rently scaled along the y-axis.

If you have recorded the measurement using
more than channel, you can select the chan­nel or sensor to be rendered in the y-axis.
Press Arrow Up (▲) followed by OK to
change the scaling of the y-axis to another
channel activated for display. This opens a
drop-down box, in which all channels are
listed. Select one followed by OK to specify
y-axis display. (The axis is displayed in the
same colour as the associated measurement
value curve - see below).
Press (►) to go to the setting field for the x­axis. Here you can change the Scaling for
the x-axis in the same way.

As a general rule, the x-axis is the time
axis. A measurement channel can be as­signed to the x-axis, for example, to render
the performance curve of a pump (P-Q
graph). In the example shown at the right,
rendering as a P-T graph has been selected
for the control line and reservoir curves.

The following options are available to you in
the function bar of the Graph menu:

Back, Automatic, Navigate, Magnifier,
Ruler, Tracker, Undo, Display all, Settings

and Info.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 58

Back:

Back/Esc enables you to return to the previ­ous menu.

Automatic:
Automatic renders all individual curves op-

timally "automatically". When selecting
Automatic (+ OK) the y-scaling is automati­cally adapted for each active channel sepa­rately, i.e. the y-scaling is zoomed to its
maximum size.

Navigate:
Navigate is used to evaluate a measure-

ment curve quickly and accurately or to ren­der parts of it. It enables the size of the

curve to be changed or the measurement
curve to be shifted, so that details can be

rendered more accurately and analyzed
more easily.

When selecting Navigate you are shown
information in the function bar about the ac­tivities possible here, including graphical tips
for using them.

Use the arrow keys of the 5-way navkey to
shift the curve or the section of the curve in
the direction of the arrow.

If you also press and hold the Shift key (↑),
you can change the size of the rendering.

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 59

Use the ► and ▲ arrow keys while holding
the Shift key (↑) down to enlarge a portion
of the measurement in the x- or y-axis.

Conversely use the ◄ and ▼ arrow keys
while holding the Shift key down to decrease
or "squash" the curve in the x- or y-axis. (cf.
screenshot)

Zoom:

To explore a specific section of the curve
and zoom into it, use the Magnifier (+ OK).
The function bar contains similar functions
for shifting and resizing as the Navigate fea­ture (see previous page).

A frame, or zoom window, appears in the
middle of the graph. The position and
size of the zoom can be changed using
the 5-way navkey and the Shift key (↑),
similar to Navigate.

Use the arrow keys ◄ & ► and ▼ & ▲ to
shift the zoom window to any place in the
graph.
To resize the zoom window, in addition to
shifting it using the arrow keys, hold the
Shift key (↑) down.

When the zoom is set and positioned in the
zooming section, OK activates the zoom
and the selected area is enlarged.

You also have the option of zooming sev­eral times in several steps, with the render­ing being further enlarged each time.

Shift: use arrow keys
Decrease/Increase:

Shift key + arrow keys

Ruler:

When the Ruler is activated, the screen ap­pears as shown in the screenshot. The func­tion bar contains the commands which can
be accessed for the ruler.

Using the arrow keys by themselves enables
you to determine the pressure at a particular
point in time. If you move the ruler using the
arrow keys parallel to the x- and y-axis to a
specific measurement point in the curve, the
associated x- and y-values are shown along
the axis, colour-highlighted with the colour of
the measurement curve.

To measure a pressure pulse in time and
amplitude, for example, use the Differential
function. Proceed as follows:

First shift the x- and

y-ruler to the starting
point of the pressure pulse using the arrow
keys. Then press the Shift key in addition
to the arrow keys and hold it down. As soon
as you actuate one of the arrow keys, a
second x- and y-ruler appears, which you
can move to the end point of the pressure
pulse using the arrow keys (continue to
press the Shift key).

Now you can release the Shift key. The
value of the pressure differential is shown
relative to the starting value along the
y-axis; the duration of the pressure pulse
(now colour-highlighted) is shown along the
x-axis. To exit the Ruler, press Esc.

HMG 3010 Page 61

Tracker:

Using the Tracker is similar to using the
ruler. The difference is that each value ac­tually measured is rendered by a point. A
ruler only appears for the purpose of "track­ing" the curve in time. The tracker "jumps"
from one measurement point to the next,
with the respective measured value of each
measurement channel shown along the
y-axis to this point x in time (x-axis).

Here, too, the differential between a selected
starting and end point of a particular curve
section (e.g. of a pressure pulse) can be
rendered and measured.

To exit the Tracker, press Esc.

Undo:
Undo enables you to undo any changes

(e.g. Automatic, Navigate, Zoom) you have
made, step by step.

Display all:
Display all renders the recording throughout

the entire recording period with all the meas­ured values. This option is used, for exam­ple, to restore the original condition of a re­cording. Display All + OK restores the
measurement throughout the entire time
period along with the complete measurement
range scaling if the ranges had been previ­ously limited.

Settings:
Settings will display the measurement

channels which have been used to make the
recording. The channel rendered along the
y-axis in the measurement curve is addition­ally labelled with "(Y)".

For rendering as a graph you can activate or
deactivate a channel by checking or un­checking the box in front of it using the ar-
row keys + OK (checkmarked means that
the channel will be shown). This enables you
to specify whether all measurement chan­nels are to be shown, or only one or two at a
time. This feature enables you to keep track
when several measurement channels are
used (cf. example on left: "Tank" is deacti­vated).

For curve rendering, there are additional
settings apart from which channels or sen-
sors are to be shown (on/off), e.g.

• Upper and lower limit

• Colouring and rendering of curves and

values

• Time range

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 63

In the list of channels, select a channel to
the right next to the box, and confirm with
OK. In the next menu you see an overview
of the measurement range, current scaling
(upper and lower limit) of the y-axis, line
style and colour in which the measured
values of this sensor is shown. You can re­set all the parameter settings except for the
measurement range.

The default scaling (upper and lower limit)
can be manually changed here via the key­pad. This is one of the various options of­fered by the HMG 3010 to enlarge interest­ing parts of graphs. After confirming the
Lower limit line with OK, you can change
the value.

Save your entry with OK. You are now in the
next line. If required, the upper limit can be
reset in exactly the same way.

For Line style a drop-down list appears of­fering you a choice of Solid line, Dotted
line, and Dash-dotted line. Make your se­lection, confirming with OK.

Colour: use the arrow keys to select various
colours from a list (confirming with OK). This
enables the rendering of every channel to be
adapted according to your preferences.

Back takes you back to the list containing
the measurement channels. The Time
range is shown above the function bar; it
can also be adapted manually as needed.
Select a value and enter another time pe­riod of interest to you via the keypad (+
OK).

After selecting Graph in the function bar,
press OK to return to the graph.

Edition 11/2011 - V04 R01 Part No.: 669855

Table

Tables are useful for displaying individual
measured values. Select Table (+ OK) in the
function bar to select a stored recording and
have its values displayed.

For a simple measurement curve recording
you are shown a measured values table list­ing the measured values of the active chan­nels in columns and the associated re­cording time in rows. No Min/Max values are
shown here as they are not captured while
recording the measurement curve.

If, however, you select the measurement of an
event log, the measured values table looks like
this:

A complete data record is shown per row for
each event. Each individual data record con­sists of the date, time, trigger event and the
associated measured values of the individual
channels including the Min and Max values.
The data record of the event recorded last
is contained in the bottom line of the table.

When more than one channel is used, the
tables of measurements in general, and
event logs in particular, have a series of
columns and rows which cannot be seen
without moving the relevant scroll bar. Use
the arrow keys of the 5-way navkey to se­lect the arrows next to the scroll bar. After
confirming with OK, you can scroll up/down
and left/right in the table.
A single arrow means scrolling line by
line or column by column, a double arrow
means screen by screen, and
means "jump to the beginning or end of the
table".

Edition 11/2011 - V04 R01 Part No.: 669855

HMG 3010 Page 66

The date and Min/Max values can be hidden
so as to make tables easier to read. You can
hide or display Min/Max and the Date di­rectly in the function bar with OK.

You can also hide or display individual chan­nels for display in the table using the Set-
tings function (a checkmark means that the
channel is displayed; activate/deactivate with
OK). You can also jump to a specific place in
the table via the date and time setting in the
column next to the beginning of the table.
Select with OK, enter the desired time using
the combination keypad, and finish with OK.
Select Table to take you back to table dis­play.

Info is used to view and modify comments
previously entered (make your entries using
the combination keypad). It also enables you
to display the recorded data for a measure­ment. To exit the Info menu, use Back.

To exit the table view of a recording, use
Back or Esc. You are now back in the selec­tion list of stored recordings. To exit it, press
OK or Esc.

To exit the View Recording menu, use
Cancel or Esc.

6.2.3 Deleting Recording

Any recording can be deleted when no
longer needed. To do this, select Delete
recording in the Recording menu + OK.
You are now shown a list of all the stored
recordings. Now select the recording to be
deleted. A small arrowhead to the left of the
file name shows you what you have se­lected.

Before selecting a recording, you can sort
the list by:

• Name

• Number

• Recording started

and in ascending (↑) or descending order
(↓) in each case.

Hit Esc to change from the recording list to
the menu in the next level up. The arrow key
(▲) enables you to access the header row.
Press OK to sort the list according to Name,
Number or Recording started. To do this,
select Name, Number or Recording started
in the header row using the arrow keys. To
sort in ascending or descending order, click
in the relevant column header with OK
(pressing OK more than once will reverse
the sorting order). An arrow next to the col­umn header indicates whether sorting is in
ascending (↑) or descending (↓) order. To
return to the selection list, press (▼) + OK.
Select the measurement to be deleted and

6.4 SMART sensors

SMART sensors are HYDAC sensors, capable of outputting several different measured vari­ables which are displayed as sub-channels of one measurement channel on the HMG. De­pending on the sensor type, these variables are stored for an extended period in the unit's
internal memory. Regardless of the sensor used, its parameters can be set.

CAUTION: To connect SMART sensors to HMG 3010 see “Connection requirements” and

“Wiring diagrams” in each sensor user manual.

The following details refer to the SMART sensor HYDACLab
apply equally to other sensors.

The measured value display of SMART
sensors is shown in the screenshot on the
right (example: HLB 1300).
The display settings and measured value
renderings can be changed as described
in section 6.1.2 above.
Since every SMART sensor goes through
an initialization phase until the actual
measured values are displayed, we rec­ommend resetting the Min and Max values
after this phase has completed.
