1.0 INTRODUCTION

This instrument is a versatile Solid State Data Recorder / Panel Indicator. It has all the capability of a traditional
paper recorder - variable chart speeds, the ability to review historic data, see trends and more, with a number of
specific exceptions - NO PAPER to jam, no ink to smudge and no pens to clog or break. The data is stored in a
Compact Flash memory card, which can be easily transported.

Of course it does all the regular functions a lot better, and the data can be transferred directly into reports,
spreadsheets or analysis programs. Data can be examined and archived on any Windows XPTM compatible
machine and can be printed out in various formats as required.

This instrument has two universal inputs so it can measure voltage, current, thermocouples and RTDs by simply
selecting them from the menu. It also has two potential free alarm output contacts and an isolated digital input. The
display can be user configured to graphics, digital or a combination. Maximum data storage is 2 Gigabytes.
Communication options include USB and Ethernet ports.

Things are done a little differently in a paperless recorder and there are a few new concepts that you may need to
become familiar with. There are more features and functions in this unit than you will probably use. It is
recommended that you read this manual in its entirety before attempting to use the instrument.

CF 151 1 AJW 10306 REV 1.0 05/07

The balance of this introduction will attempt to introduce some of the more unique features of this paperless
recorder.

1.1 Chart Speed to Sample Speed

A major difference between paper and paperless is SAMPLE SPEED, which is analogous to CHART SPEED in the
paper recorder. There is an apparent chart speed, the rate at which the samples appear to move across the
Graphics Display, but unlike paper recorders the display is made up of discrete data points, each of which is a
distinct sample of the data being measured. The rate of movement across the screen is thus a direct function of the
sample rate. The major factor in deciding what sample rate to select is knowing how much data is enough. In a
paper recorder a chart speed of 1 inch per hour is fine for a process that does not vary very quickly but would result
in a thick blur if trying to record a 1Hz sine wave. Unlike a paper recorder, every point recorded by the paperless
recorder is uniquely identifiable, no matter how dense it appears on the screen. It is always better to have too much
data than to have too little. The only consideration is the amount of space used in the memory card.

To relate chart speed to sample rate we need to consider how we plan to reproduce the data. The graphic LCD
display has a density of 70 pixels (data points) per inch; a typical dot matrix printer has 180 pixels per inch and a
laser printer 300 pixels per inch. Thus to fill one inch of the display in one hour we need to sample at a rate of 70
samples per hour, a little over once per minute, however if this is now printed on a laser printer it will fill less than
1/3 of an inch. It is the amount and quality of the data that counts. Another advantage of the paperless recorder is
that it can sample internally at 100 samples per second (one every 0.01 seconds). These samples can be averaged
or peaks or valleys can be detected and then this data can be stored at the chosen sample rate.

Trial and experience will yield the best sample speeds for the application. Start with a faster sampling rate than you
think you will need; you can always slow it down in the future. As a rule of thumb, one sample every 10 seconds
should give the equivalent information that 1 inch per hour of chart paper would.

1.2 Reviewing Data

One of the biggest features of this recorder is its ability to show historic data and trends. The data on the graphics
screen can be rewound like a tape recorder, scrolling back in time, displaying past data on the screen while still
recording data in real time.

The data can also be compressed on screen, showing a whole day or week's worth of recording on one screen,
enabling trends or irregularities to be spotted easily. A data cursor can be moved around the screen to uniquely
identify samples in both time and amplitude.

Refer to the Section 3 for the specifics on reviewing data.

1.3 Zooming and Conditioning Data

The recorder acquires data with greater resolution than can be displayed on the screen. The user has the ability to
ZOOM in to amplify the data either 2 or 4 times, equivalent to using a magnifying glass on the display. These
ZOOM windows can be scrolled up or down to cover the entire data spectrum. The vertical scale automatically
adjusts to the zoom level and position to enable resolution of minor changes in input signal.

The recorder also acquires data at a rate faster than what may be displayed on the screen. The user can set the
sampling rate from 100 samples per second down to 1 sample every 10 minutes. When sampling slower than 100
samples per second, the recorder can be programmed to record the average, maximum or minimum values. Thus if
a sample rate of 1 sample per minute is chosen, the recorder will still sample internally at 100 samples per second
while computing the average or detect and store either the maximum (peak) value or minimum (valley) value,
depending on the mode programmed. It will then store this value when the minute is up. Unless required otherwise,
it is recommended that the average value be used for recording since this will tend to filter or smooth the data. See
Advanced Setup Menu for details.

1.4 Customizing

There are many operating features and parameters that the user can program. All settings are stored in nonvolatile
memory and are recalled each time the unit is powered on. The display can be scaled to read in engineering units,
and the trace can be labeled accordingly with up to three alphanumeric characters. Four alarms are fully user

CF 151 2 AJW 10306 REV 1.0 05/07

programmable and can be associated with either channel or the external input. The Alarm levels can be set in the
engineering units of the display, the sense of the alarm, the type and the deadband or hysteresis can be individually
set for each alarm. Optional relay outputs can be assigned independently to each alarm. A reset delay feature is
also available.

There are other features which may be programmed by the user including the time stamping mode, either real time
or elapsed time, clock update rates, file names, beeper operation etc. (Refer to – Advanced Setup)

1.5 Triggering

The recorder has the ability to change sampling speeds and stop or start recording as a result of a triggered event.
This event may be tied to any of the four internal alarms or optionally to an external signal. This enables the unit to
monitor a process without recording or to record at a slow speed to conserve card space. When an external event
or internal alarm condition occurs, the unit will begin recording or change to a higher sample rate for the data of
interest.

1.6 The Graphics LCD Display

Recorder Front View showing TREND Display

The above diagram is a representation of the recorder in the TREND mode. The alpha characters around the
border point to various features of the unit and are described below. Not shown are the MENUS which pop up over
the display. The menus are in the form of those shown in Sections 4 and 5. The numbers in parenthesis below refer
to the section that covers the topic in detail.

A CompactFlash™ card slot – manually insert a card into the unit to store data and configuration information. Can

also be used as a means of updating the firmware in the unit. Cards up to 2 Gigabytes in size can be used.

B Busy LED (Red) – on when the unit is recording and blinks rapidly whenever the unit is accessing the

CompactFlash™ card. Blinks at 1 second rate if unit is triggered but not recording. Do not attempt to remove
the card when this light is on.

C Power LED (Green) – on during normal operation. If the optional internal battery pack is present, this LED will

blink during power failure to indicate the unit is running off internal batteries.

D Optional USB interface – enables connection to a Windows XP compatible PC.

CF 151 3 AJW 10306 REV 1.0 05/07

E Navigation buttons – used to set up and navigate around the display. The buttons are all dual function; the

second function is initiated by holding down the MENU button while pressing one of the other buttons. The
second function is printed on each button.

F Date and Time – shows the actual time of day (real time). The time is displayed user selectable in 12 or 24 hour

format. The user can also select European or American formats and auto daylight savings adjustment. See
Clock setup.

G Zoom Scale Indicator – shows the zoom scale for the channel indicated if > x1. Separate scale for each

channel. See zooming.

H Right hand edge of the graphics area in which the traces are displayed. This is the vertical scale area

designated by the scale values at the top, center and bottom of the scale. The most recent data that is
displayed in digital form at the top of the display (J) is against the right edge of this scale and moves left with
time - the most recent data is to the right and the oldest data is to the extreme left. New data appears against
this margin and the oldest data disappears off the screen at the extreme left. The graphic cursor (K) will start
against this right edge.

I Vertical Scale Identifier – this display alternates between Channel A and Channel B. It displays the Channel

Tag and the Engineering units. See Channel setup.

J Digital Window – the top of the screen displays the values for each Channel including the Channel identifier,

the current value and the engineering units. Channel A is displayed on the left and Channel B on the right. This
window displays the absolute digital value of the instantaneous (last) reading for the channel, and is the right
most sample value on the trend display (G), unless the cursor is active. In that case it shows the value at the
point the cursor intersects the trend line.

K Cursor – is displayed when activated in the cursor ID mode. This cursor can be moved using the left ◄ and

right ► arrow buttons. The values in the digital window (J) are the values at the point where the cursor
intersects the trend line.

L Date/Time Axis Delimiter – the dotted vertical lines placed at equal increments along the Horizontal axes

(Time). The Date/Time stamp beside the line indicates the exact position of the line. Both date and time may be
shut off or relocated vertically. These lines move with the trace at a speed dependent on the sampling speed.
This is configurable in Display Setup.

M Channel B Trace – the trend line is the graphic representation of Time (horizontal) versus Amplitude (vertical)

and is shown solid to distinguish it from the Channel A trace, which is shown as a dotted trend line. This is
configurable in Display Setup.

N Graphic TREND Window – shows the channel traces, which may be compressed, expanded, zoomed, scrolled

and halted.

P Status Icons – these icons appear at various times to indicate the status of the unit and the display. From left to

right they are:

• The numbers 1,2,3 and 4 are the ALARM indicators - one for each alarm. The numbers are present when the
alarm is enabled and will blink if the alarm is in an alarm condition.

• The X indicates the status of the EXTERNAL INPUT and is present when the external input is present.

• The

icon indicates the display is compressed. The horizontal time stamps indicate the current

compressed values. The display can function normally in compressed mode, may be paused or the user can
scroll back and forth using the left ◄ and right ► arrow buttons.

• The H indicates the display is in the HOLD condition. While in HOLD, the trends do not update. The display
enters the HOLD condition when the ID Cursor (K) is present or the user scrolls in the horizontal direction
using the left ◄ and right ► arrow buttons. Exit the HOLD mode by pressing the MENU button.

DO NOT INSERT OR REMOVE THE COMPACT FLASH CARD WHILE THE BUSY LED IS ON!

1.7 Other Graphic Modes

In addition to the full screen trend mode shown section 1.6, there are two additional graphic display modes.

CF 151 4 AJW 10306 REV 1.0 05/07

The Dual Digital mode, as shown below, enables both channels to be shown as Digital values similar to a digital
panel meter. The user has the option of showing the displays in normal or reverse video (shown) modes, and the
display can be set to blink on Alarm Condition.

The other Graphic mode is a split screen with the trend in the top half and the digital display in the lower half as
shown below. When selecting this mode, Channel B is the default digital value, but can be switched in the
Advanced Setup menu.

2.0 INSTALLATION AND SETUP

AC Power Requirement (External adapter) 100 - 240 Vac ~ 50/60 Hz

NOTE: The recorder is designed to be panel mounted and as such should be considered as permanently

connected. Disconnection from the supply must be possible via a customer supplied switch or circuit breaker. This
disconnection device must be included in the panel installation and should be clearly marked, it must be in close
proximity to the Recorder and easily accessible to the operator.

NOTE: In order to fully comply with the CE EMC Directive 89/336/EEC, connections to the recorder should not
exceed 3m (9.8ft) without adding additional filtering.

The Recorder fits in a standard ¼ DIN panel cutout of 92 x 92 mm (3.62 x 3.62 in.) and requires 140mm (7.5
inches) panel depth not including space for power and input source cable. The thickness of the panel is immaterial,
but panels thicker than .125 inch will require that the locking bars be cut down. Actual dimensions are shown below
in Figure 2.1:

WARNING: Do not use this instrument in any manner inconsistent with these operating instructions or
under any conditions that exceed the environmental specifications stated.

2.2.1 Panel Mounting

The Recorder should be mounted in a vertical panel to ensure proper operation. Ensure you have the proper
clearances and proceed as follows:

2.2.1.1 Cut a panel opening 96 mm x 96 mm (3.62 x 3.62 in.).

CF 151 6 AJW 10306 REV 1.0 05/07

2.2.1.2 Remove any packaging material from the Recorder. Always handle the unit carefully to avoid damaging
the LCD display or scratching the display surface.

2.2.1.3 Remove the locking bars from the Recorder enclosure by removing the captivating screws

2.2.1.4 Insert the Recorder, rear end first, through to front of the panel opening.

2.2.1.5 With the Recorder held firmly in place against the panel, install one of the locking bar assemblies from

the rear, by sliding the locking bar tongue into the groove on the side of the Recorder enclosure as
shown in Figure 2.2.

2.2.1.6 Insert the retaining screw into the rear of the groove. Using a Phillips screwdriver, tighten the screw
until the locking bar is just pressing against the panel.

2.2.1.7 Install the other locking bar assembly into the groove on the opposite side of the Recorder enclosure
and tighten as before.

2.2.1.8 Using the screwdriver, tighten both screws so that the Recorder is held firmly in place. Do not over
tighten, to avoid stripping the threads.

Figure 2.2 Rear View - Installation

2.3 Connection

2.3.1 Power Connections

NOTE: The Recorder is designed to be panel mounted and power should be considered to be
permanently connected. Disconnection from the supply must be possible via a customer supplied switch
or circuit breaker. This disconnection device must be included in the panel installation and should be
clearly marked, in close proximity to the Recorder and easily accessible to the operator.

THE RECORDER IS DESIGNED TO OPERATE ON 9 Vdc. DO NOT CONNECT AC POWER DIRECTLY TO THE
UNIT AT ANY TIME.

CF 151 7 AJW 10306 REV 1.0 05/07

The power connector is located on the rear panel in the top left corner. There are two voltage
options available for the recorder – the standard is 9Vdc, which is used with an external universal
AC Mains power supply. The external wall power supply is a high efficiency switcher that will work
from 100 to 240 Volts AC 50/60 Hz. The other power option is an isolated 12 to 24Vdc input for
use with an external DC power supply. The power supply option is marked with a dot in a square
on a label above the power connector as shown in Figure 2.3. Check the unit to ensure that the
power and inputs are as expected.

Figure 2.3

Before connecting any power or inputs to the unit, ensure that all signal wires and power cables are at zero voltage.
The DC power is applied to the unit via a three-way screw terminal connector. The power supply is supplied with
two tinned leads, the positive lead is identified by the RED shroud over the wire. The third connection is for system
GROUND. You will require a small flat-head screwdriver. Connect the power and signal wires accordingly, noting
carefully all polarities. Ensure that the unit is properly grounded to a suitable ground within the cabinet.

Loosen the screws on the terminal block and insert the exposed conductor cable from the power supply below the
screws, under the metal plate. Ensure that the insulation is flush with the terminal block. If it is too long, remove the
cable, trim and reinsert. Tighten the screw to firmly hold the cable. Ensure the ground wire is connected and
properly grounded at the other end. If you are not using the supplied wall power supply, follow the same procedure
carefully identifying the positive supply line. The unit is protected against reverse polarity but not against substantial
over voltage.

2.3.2 Input Signal Connections

The maximum input on any input channel is 25 Volts DC. Voltages higher than this may permanently
damage the unit.

Ensure the unit is powered down before connecting any inputs.

There are two universal analog inputs – Channel A and Channel B. Each is programmed independently of the
other. Inputs can be voltage or current (50mA max using an external shunt), thermocouples, RTDs or TTL
compatible pulse inputs. Isolation is provided between inputs and the rest of the system. The channels are not
isolated from each other. Connection detail for the various inputs is shown in Figure 2.4.

CF 151 8 AJW 10306 REV 1.0 05/07

Figure 2.4 - Connection Detail

When connecting the signal wires, keep polarities correct. The screw terminals are marked on the rear panel - there
are four connections per channel. The high or positive signal marked IN+, and a low or common signal marked IN-.
The terminal marked Vo is the Auxiliary voltage output used to drive external sensors at +5Vdc and a maximum of
50mA. The terminal marked I+ is the 1mA current required for RTDs or resistors. Any screen or shield (often the
braided wire) should connect directly to the system ground and is used to shield the low level input signals from
induced noise pick up.

Connect the signal wires to the terminal block in the manner described above. Use wire of adequate gauge to carry
the signal. The mA input requires the use of an external 250 ohm shunt (Check with supplier). Thermocouples
should be connected with thermocouple wire of the same type as the input; the terminal block is the reference
junction. Connect any sheath or braid to the GROUND connection. RTDs have an additional wire, the current
source, which is connected to the terminal marked I+. See Figure 2.4.

WARNING: Unused inputs must have IN+ and IN- commoned together.

CAUTION: Never run signal and power or control wiring together in the same conduit. This practice will
prevent possible recording error due to induced signals between lines. Route signal wires away from
power wires at the rear panel.

NOTE: Ground cable shields at one end only to eliminate the possibility of interference due to ground loop
currents. When grounded transducers are used, the shield should be grounded at the sensor end only.

2.3.3 Relay Output Connections

To prevent the possibility of electrical shock, use extreme caution when wiring contact output
connections. Hazardous potentials may exist on contact output terminals that are floating with
respect to instrument ground. WIRES FROM REMOTE SOURCES MAY CONTAIN DANGEROUS
POTENTIALS. ENSURE ALL POWER SOURCES ARE DISCONNECTED BEFORE WIRING RELAY
CONTACTS.

The relay contacts are rated for AC or DC operation (Maximum recommended voltage - 30 Volts.) Each relay has a
set of potential free contacts. There is no polarity to the terminals; it is a normally open contact that closes in alarm
condition. These contacts are internally suppressed for EMI/RFI and High Voltage transients resulting from
inductive loads. The relays may be programmed as fail safe, which means they are energized in the “off” condition.
This way if the power should fail the relays will open into the alarm condition. See note below.

2.3.4 Digital Input

The digital input is optically isolated and is activated by an external dc supply of 5 to 12Vdc at 20mA. The input is
via the DIGITAL INPUT + and – terminals. The - connection is the COMMON for the external input, while the + is
the input for the positive voltage.

CF 151 9 AJW 10306 REV 1.0 05/07

The digital input may be used as an External Trigger to stop or start recording, or may be used to change the
sampling speed. Thus the unit can be set to record only when a conveyor is running for example. The External
Trigger may also be linked internally to the optional Relay Output. This could be used as a remote "record active"
indicator. Refer to Sections on Relay setup and External Input setup.

Note: In order to fully comply with the CE EMC Directive 89/336/EEC cables to the relay output and digital input
should be looped through a ferrite (Type Steward 28R2025-0R0 or similar) close to the terminals.

2.3.5 USB Port (Option)

The USB Port is an option and will be installed only if specifically ordered. It is a serial connection to a PC that
allows the user to program the recorder remotely, start or stop recording and download real time data.

Refer to the separate manual that is supplied with the USB interface option.

2.3.6 ETHERNET Port (Option)

The Ethernet Port is an option and will be installed only if specifically ordered. It allows the user to program the
recorder remotely, start or stop recording and download real time data. The IP address is set in the Advanced
SETUP Menu Refer to the separate manual that is supplied with the Ethernet interface option.

2.3.7 Isolated DC input (Option)

The unit may be powered by an external DC source with the isolated DC to DC option. Connect the unit to the
external DC source and observe the voltage and polarity of the inputs. In order to fully comply with the CE EMC
Directive 89/336/EEC the power cable should be looped through the ferrite bead provided, close to the terminals.

2.3.8 Cleaning

The unit may be cleaned by wiping with a soft cloth. The front panel and display / keypad may be wiped with a
slightly damp soft cloth containing soapy solution or a mild detergent. Do not use any lemon based (citric acid)
product to clean the display / keypad. NOTE: THE UNIT IS NOT WATERTIGHT.

2.4 Input Scaling

The input to the recorder is often a standard process variable (e.g. voltage) rather than the actual units being
measured (e.g. pressure).

There are a number of custom conversions available in the unit to take care of special inputs such as
thermocouples and RTDs, which need special scaling and linearization. These are preset in the unit and require no
modification. There is also the capability to customize any input variable that has a linear relationship to the
measured variable. The relationship between the required variable and the input variable must satisfy the equation
for a straight line: y = mx + b
where y is the output value to be displayed and recorded, x is the input variable (typically volts or milliamps DC), m
is the scale factor (slope of the line) which defines the relationship between the input and the displayed variable
and is a constant (linear relationship), and the factor b (known as the y intercept) is a constant offset variable that
may be positive or negative.

This facility to scale the input is found in the ADVANCED SETUP menu and is available to each channel
independently. Here the user can easily scale the input and set the displayed units using three alphanumeric
characters.

The scaling is achieved in the unit in the CHANnel X SETUP option (X = A or B) in the ADVanced SETUP menu.
First set the displayed LO SCALE, which may be positive, negative or zero. Then set the displayed HI SCALE for
the full-scale input. The unit will then automatically compute the scale factor and offset.

Setting the engineering units is done in the same menu location using the CHAN UNITS option to set the three
alphanumeric characters.

Let us assume we have an input from a pressure transducer of 1 to 5 volts DC, corresponding to real world units of
zero to 250 PSI (Pounds per Square Inch of pressure). Assume we choose the 0 to 5 volt input. The actual output
span of the transducer is 4 volts, with 1 volt = 0 PSI and 5 volts = 250 PSI. This is equivalent to 62.5 PSI per volt.
The LO SCALE which is the "0" volt value is equivalent to -62.5 PSI and should be set to this value, and the HI

CF 151 10 AJW 10306 REV 1.0 05/07

SCALE is set to "250". The engineering units are set to "PSI". The display will
now show zero to 250 PSI for 1 to 5 Volts input. The linear scaling is shown in
Figure 2.5.

2.5 Alarms

The Recorder has four programmable internal alarms with dual relay output.
The alarms can be associated with either analog input channel, can be set as
high or low, latching or non-latching with or without lockout capability. Each
relay has a set of potential free normally open contacts (Form A - SPNO) that
are accessible from the rear panel via screw terminal connections. Alternatively
the relays can be set to the failsafe mode, normally closed (Form B – SPNC). The relays can be assigned to any,
all or none of the alarms. Refer to section on Alarms and Relays in Advanced Setup Menu.

2.5.1 Alarm Types

A high alarm is active when the input is greater than the setpoint. A low alarm is active when the input is less than
the setpoint. A latching alarm will remain set once activated and must be reset by the operator. Note that the
alarm condition should be removed before resetting the alarm or the alarm will activate and latch again. A non-
latching alarm will set on alarm condition and automatically reset once the alarm condition is removed. A
differential, known as hysteresis or deadband can be introduced so that once an alarm is set (at the setpoint), the
input must go beyond the deadband before the alarm resets. This prevents the output relays from chattering in
borderline conditions. The deadband is set in absolute units and adds to the setpoint in a low alarm, or subtracts
from the setpoint in a high alarm. By way of example, if the setpoint is 100, the hysteresis (deadband) is set to 5,
and the alarm is a high type and non-latching, then the alarm will activate when the input exceeds 100 and will
remain active until the input drops below 95 (100 minus 5). Alternatively the user can set a reset delay from 1 to
255 seconds. This delay must time out once an alarm condition has been removed before the alarm will reset to
normal.

Lockout prevents an alarm from activating until the setpoint has been traversed in the opposite sense by the input.
For example, if we were measuring pressure and had a low alarm set at 100, we may not wish the alarm to be
active on start up when the pressure may be low or zero. We really wish to monitor a low-pressure situation once
our target pressure has been reached, say 150. The lockout prevents the alarm activating at startup. The alarm
remains deactivated until the input exceeds the setpoint. Now the alarm arms and any future time that the input
drops below the setpoint, the alarm will activate.

2.5.2 Setting

Setting and configuration is done in the Advanced Setup Menu.

The alarm setpoints are set in the same units as the input type and may be different for each channel. When setting
the actual setpoint value, the value may be incremented in steps other than what is expected (unit steps). This is
due to the fact that the input is converted into a digital value with a finite resolution. It is not possible to set a
setpoint value that cannot be resolved by the internal microprocessor. Select the closest value to the exact value
you require; it will always be with 0.5%. The same applies when setting the deadband.

Note that when configuring the alarms, there is no correlation between inputs, alarms and relay outputs. These are
user defined. Each alarm can be assigned to only one input channel.

When setting up each alarm channel, the user should DISABLE the alarm so that parameters may be changed
WITHOUT AFFECTING THE RELAYS. This is done in the ALARMS menu by selecting the ENABLE option so that
no √ appears to the left of this option. Once everything is set, select ENABLE once more to activate the alarm,
indicated by the presence of the √. (Refer to Section on Setting Alarms)

⇒ When setting up alarms, you may get unexpected results from the relays if they are enabled. Ensure there

is nothing connected to the relays that could result in an accident due to random closing of the relays
during setup and always DISABLE the alarm as described above. Make the changes and then re-enable
the alarm.

There are many different ways the alarms can be set up. All the alarms can be assigned to a single channel and
may be of the same type giving for example a various degrees of high warning and ultimately a high shutdown

CF 151 11 AJW 10306 REV 1.0 05/07

indication. Also, the relays may be assigned to any combination of alarms. This would allow a single relay output to
indicate any alarm active. The combinations are endless.

2.5.3 Alarm Indication

There are three indications of alarm condition: the relay outputs, visual icons on the display and audible alarm.

When an alarm is armed and functioning, it is indicated by a small "1", "2", "3" or "4" in reverse video on the bottom
left hand side of the graphic display. These status indicators remain on as long as the alarm is enabled. If an alarm
is triggered (in alarm condition), the status indicator will blink and the internal beeper will sound. The beeper can be
permanently disabled from the Advanced Setup Menu - BEEPER - ALARMS - OFF.

The relays close on an alarm condition, assuming they have been set up correctly. The relays can be set as fail­safe by reversing the logic of the alarms (Advanced Setup Menu - RELAYS - FAILSAFE).

2.6 Memory Cards

The memory cards used are standard CompactFlash™ cards. We recommend the use of Sandisk™
CompactFlash™ cards. The cards are keyed and can only go into the recorder right side up. The largest capacity
card that can be accommodated is 2 Gigabytes.

2.6.1 Care of the Data Cards

Do not expose the cards to direct sunlight or extremes of temperature for any length of time. Do not expose to
moisture. Do not bend or twist. Avoid high static discharge. Mail in suitable packaging to avoid postal damage.
When transporting, use an anti-static bag or the plastic enclosure in which the card is supplied.

2.6.2 Card Storage Capacity and Data Type

Depending on what else is stored on the card (e.g. configurations files, other data files), data storage capacity can
be roughly calculated by the following formulas:

Number of samples is card size divided by 4.4. The time that it will take to fill a card is roughly the number of
samples divided by the sample rate. For example, a 32MB card will hold roughly 32,000,000 divided by 4.4 =
7,272,727 samples. At 5 samples per second this is 1,454,545 seconds or 404 hours or approximately 16.8 days.

If you show the Card Status window (MENU - CARD STATUS), it will indicate how much time is left on the card. It
also displays the current Filename that is being used for recording.

The files on the card are in DOS standard format and can be managed on any Windows™ based machine with a
CompactFlash™ reader - internal or external. The content of the files is in proprietary binary format and requires
special software to read the data. All units are supplied with the Navigator Lite Software, which allows the data to
be exported to Excel.

This space intentionally left blank.

CF 151 12 AJW 10306 REV 1.0 05/07

3.0 BASIC OPERATING INSTRUCTIONS

The Basic mode of operation encompasses those functions that would be done on a routine basis and relate
primarily to viewing and reviewing data with some use of the menu system. The advanced mode, while technically
still simple to operate, involves setting up the unit and would typically need to be done only once.

3.1 Basic Mode of Operation

Basic operations are all done using the five buttons on the front panel (shown below) and the first level menu.

Each arrow button has dual functions. The second function is activated by pressing and holding the MENU (2nd
Function) button and then pressing any of the other buttons. The 2nd function of each button is denoted by the text
under the arrow symbol. (EXPAND, COMPRESS, ZOOM + and ZOOM -).

The unit need not be recording to the memory card in order to manipulate data. The data available however is
dependent on how long the unit has been operating, the sample rate and the buffer or memory card size.

3.2 Viewing Historic Data

Any data that is not currently visible on the screen is historic data. To view past data, the left (◄) and right (►)
arrow buttons are used to rewind (◄) or fast forward (►) the data (scrolling). When rewinding, data will be retrieved
from the memory card or from the internal buffer and is available as far back as the start of recording. When fast­forwarding, data is available up to real time. The time and date stamp on the screen indicates the relative time of
the samples being viewed. Depending on the amount of data to process there may be delays before the screen
reacts.

Historic viewing by scrolling is limited to the file (or files) created since recording was manually started via the
RECORD MODE Menu - ON. If NOT recording, scrolling back in time is limited to the content of the internal buffer.
The history buffered is dependent upon the sampling speed. Data is presented as latest data first.

It is possible to view data from other files of previously recorded data (or even data recorded on another machine)
using the View File menu.

⇒ At any stage during the rewind or fast forward process, the screen can be restored to current or real time

display by pressing the MENU button.

⇒ When the data on screen is not current, an

appears on the status line to indicate that the rewind or

compress mode is active and the data is on Hold.

3.3 Compressing and Expanding Data (Trend Viewing)

In order to view data trends, it is often necessary to pack more data onto the screen than is normally visible in real
time. To compress the data, press and hold the MENU (2

nd

Function) key and then press the COMPRESS (.) key.
Each time this key is pressed the amount of data on the screen will double up to a maximum of 32 times
(equivalent to 5 sequential key presses). Once compressed, data can be rewound and fast-forwarded as described
in the previous section. The data can be expanded back after being compressed by pressing and holding the
MENU key and then pressing the EXPAND (◄) button.

Note that compression displays peak values (both high and low). Thus even though data is compressed, all
amplitude information is present on the display. At compressions of 16 times or greater, the redraw time of data on
the screen slows down due to the large amounts of data that must be manipulated.

⇒ At any stage during the compression or expansion process, the screen can be restored to current or real

time display by pressing the MENU button.

⇒ When the data on screen is compressed, a

appears on the status line to indicate that the compress

mode is active.

CF 151 13 AJW 10306 REV 1.0 05/07

3.4 Zooming Data (Amplification)

As a result of the small display area available, it is not always possible to see small changes in amplitude of the
recorded signals even though the resolution of the internal converters can measure it. To overcome this problem
you can ZOOM in on a portion of the graph and get increased resolution.

ZOOM applies to each channel independently. The trace that will zoom is the one whose scale is shown to the
right. To adjust the other trace simply wait for its scale to appear.

To ZOOM in and amplify the graph, press and hold the MENU key, press the ZOOM+ (▲) button and then release
both buttons. The display will zoom in by 2. Note that the scale units change to reflect the increased zoom level.

There are three zoom levels available: x1, x2 and x4.

To decrease the zoom level (or zoom out), press and hold the MENU key, press the ZOOM- (▼) button and then
release both buttons.

While adjusting the zoom, scale flipping is suspended. Turning the other trace off will also suspend flipping.

Note that when zoomed in at any zoom level, the (▲) and (▼) buttons will move the graph relative to the window
enabling viewing of any part of the graph within the zoom window. When zooming, the trace expands or contracts

about the centerline. If zooming drives the trace off the screen, it will automatically reposition itself at the top or
bottom vertical edge of the chart. Once in a zoom level, all functions are operational on the zoomed display.

⇒ When in a zoom mode, the zoom level is indicated in the lower half of the scale for the associated channel

(X2, X4 etc.). No indication indicates normal scale (X1).

⇒ To exit the zoom mode, zoom out (MENU + ▼) as far as possible until the scale value disappears – x1

mode.

3.5 Menu Mode

At any time when in normal view mode, pressing the MENU button will bring up the user
menu as shown to the right. Note that the menu "pops up" over the graphics display. The unit
continues to record and will not lose data. There is also a time out option that will return a
menu display back to a graphic display after a period of inactivity. (Refer to Advanced Setup
DISPLAY - MENU TIMEOUT).

⇒ When the menu is active, the Left Arrow (◄) and Right Arrow (►) buttons act as

ESCAPE keys to return to a previous level without activating any function.

The user moves about the menu using the Up Arrow (▲) and Down Arrow (▼) buttons. The
current selection is always highlighted in reverse. To select a function, simply move to it with

the (▲) and (▼) buttons and then press the MENU button once. To go back a level without
activating any function, simply press the (◄) or (►) buttons. Note that the menu has more options than can be

displayed at once on the screen. When a selection gets to the top or bottom of the menu list, the list will scroll until
the last entry is reached then wrap around. Pressing and holding the (▲) and (▼) buttons will activate an Auto

Repeat function and cause the highlight bar to scroll automatically.

The menu has multiple levels. An option with a secondary level is indicated by .. after the name. Access to the
various levels can be controlled by a password (Refer below).

3.5.1 Exit!

When the menu is displayed, it defaults to the EXIT selection. At this point, pressing the MENU button will return to
the graphic display.

CF 151 14 AJW 10306 REV 1.0 05/07

3.5.2 Alarm Reset!

Pressing the MENU button after selecting ALARM RESET! will reset any alarm that is active and latched and then
exit the Menu Mode. If the alarm is not latched but is still in alarm, selecting this option will briefly reset the alarm,
which will then activate again.

3.5.3 Record Mode..

To begin or end recording in the data card, press the MENU button, use the Up Arrow (▲) or Down Arrow (▼) button
to highlight RECORD MODE and then press the MENU button again. Several options appear in a sub window:

OFF, ON and TRIGGERED. To exit at this stage without changing the current setting, press either the Left (◄) or
Right (►) Arrow button. Otherwise, use the Up Arrow (▲) or Down Arrow (▼) button to make a selection and then

press the MENU button. The active selection is indicated by a √ to the left of the option. If you are using the alarms
or external input to control the recording, select TRIGGERED for triggered operation. OFF and ON will always stop
or start a recording irrespective of the state of any of the record triggers. (Refer to Event Triggering.)

⇒ The RECORD MODE menu option may be password protected.
⇒ Before selecting ON or TRIGGERED to begin a recording, ensure that a Memory Card is in place and that

there is sufficient space available to contain your new data. (Refer to CARD STATUS below.)

To return to the graphic screen, press either the Left (◄) or Right (►) Arrow button. For further details on other
options under RECORD MODE, refer to ADV. SETUP - DATA CARD.

Note: While recording, the recorder automatically switches to OFF when a card is removed, or if it is not present
when power is applied. This will require a manual restart of the recording when a new card is inserted. If the card
remains in the slot while power is removed the recorder restores the recording state it was in when the power was
interrupted.

3.5.4 Cursor ID!

The Cursor ID mode enables the user to accurately pinpoint the time and amplitude of any sample in the graphics
window. The unit has to be in the full graphic mode for this option to work.

To enable this function, press the MENU button, use the Up Arrow (▲) or Down Arrow (▼) button to highlight
CURSOR ID! and then press the MENU button again. The Menu will vanish revealing the Graphics screen and a

single data cursor against the right edge of the display area. Note: The Cursor ID mode will not activate if the
Trend is compressed. The screen will be in the HOLD mode and the data window at the top of the screen and
time/date stamp at the lower right will show the values of the samples under the data cursor. The status line will

show the highlighted

to indicate that the data and timestamp is that of the data under the cursor and not real

time data.

Using the Left (◄) or Right (►) buttons the user can move the data cursor to the point of interest. The data window
at the bottom of the screen will show the time and date of the sample and the digital readings at the top of the
screen - A (and B in dual channel units) show the absolute value. Note that at the extremities of the data, the cursor
hits an end point and then the data scrolls beneath it. This method can be used to accurately identify unique points
on the graphics display no matter how busy the traces appear.

To return to normal (real time) mode, press the MENU button. Note that entering the Cursor ID mode does not
affect the real time acquisition of data.

3.5.5 View File

The user can view data from files other than the one currently being recorded. The View File option allows the user
to view previously recorded data on the data card from the very first file through to the current data. The display
HAS TO BE IN THE FULL GRAPHIC MODE for this to work.

To view a file on the memory card, press the MENU button, use the Up Arrow (▲) or Down Arrow (▼) button to
highlight VIEW FILE and then press the MENU button again. The current filename will be displayed. To view

historic data from this file, simply press the MENU button. To choose a different file on the memory card, press the

CF 151 15 AJW 10306 REV 1.0 05/07

Left Arrow (◄) button twice to display a directory listing of all files on the card. Then use the Up Arrow (▲) or Down

Arrow (▼) button to highlight the desired file and press the MENU button twice to select it.

When viewing from a file, the status line will show a highlighted

to indicate that the data being viewed is from a

File on the memory card. All View, Compress and Zoom functions work on the prerecorded file. Use the Left (◄) or
Right (►) buttons to move through the file. Data will be presented as oldest samples first.

To return to the current real time trend, press the MENU button. View File will automatically abort if the data card is
removed.

3.5.6 Card Status!

To display the status of the memory card, press the MENU button, use the Up Arrow (▲) or Down Arrow (▼) button
to highlight CARD STATUS! and then press the MENU button again. A pop-up window will be displayed showing

information about the memory card including the size of the card, the amount of space left as a percentage and the
equivalent record time at the current settings.

To remove the Card Status pop-up window, select CARD STATUS! again.

3.5.7 Sample Rate

To adjust the sample rate (the rate at which data is recorded and displayed), press the MENU button, use the Up
Arrow (▲) or Down Arrow (▼) button to highlight SAMPLE RATE and then press the MENU button again.

⇒ The SAMPLE RATE menu option may be password protected.

When entering the SAMPLE RATE menu, the rate highlighted is the current sampling rate. To exit at this stage
without changing the current setting, press either the Left (◄) or Right (►) button. In this manner the user can
check the current sampling rate at any time without affecting the recording.

To change the sampling rate, use the Up Arrow (▲) or Down Arrow (▼) button to highlight the desired sample rate
and then press the MENU button. The sample rates vary from a high of 100 S/sec (Samples per second) to the
slowest 10 min/S (minutes per sample, sec/S is seconds per sample).

To return to the graphic screen, press either the Left (◄) or Right (►) button.

3.5.8 Password (Protection)

To set, reset or change a password, press the MENU button, use the Up Arrow (▲) or Down Arrow (▼) button to
highlight PASSWORD and then press the MENU button.

⇒ This menu option may be password protected.

Follow the prompts. Enter a 4-digit password using a combination of ◄►▼▲ buttons. The key presses are echoed
in a pop-up window and roll around, first in first out. Once you have entered your password, press the MENU
button.

If you are entering a new password, you will be asked to repeat your password and then press the MENU button. At
this point the password is entered and the unit is protected.

To clear the password, enter the current password and then simply press the MENU button when prompted to enter
the new password. A null password is no password at all.

3.5.9 Adv. Setup (Advanced Setup)

See Section 4.

3.5.10 Display Adj (Adjust)

To adjust the backlight brightness and viewing angle, press the MENU button, use the Up Arrow (▲) or Down
Arrow (▼) button to highlight DISPLAY ADJ and then press the MENU button again.

CF 151 16 AJW 10306 REV 1.0 05/07

Adjust the Viewing Angle using the ◄ and ► keys and the Backlight Intensity using the ▲ and ▼ keys. Press the

MENU button to accept the changes and exit.

3.6 Event Triggering

The recorder has the ability to be triggered by certain events that are generated internally or, optionally, externally,
which will enable it to automatically change sampling speed or begin or end a recording session. The trigger can be
any alarm or the external input. The user can thus set the unit to record at a slow sample speed until some alarm
condition is triggered and then change to a higher sample rate to record the transient. Another example is the use
of the external event trigger to start and stop recording allowing the selective recording of specific events.

The event triggering is setup in the Advanced Setup Menu option. The control of recording, stopping and starting is
set in the REC. TRIG. (Record Trigger) menu option (Section 4.9), while the changing of sample speed is controlled
via the SAMPLE TRIGger menu option where a second set of sample speeds will be presented for the triggered
speed change (Section 4.8). This rate may be slower or faster than the regular rate depending on application.

The external event may be used in the same manner as the internal alarms for triggering a change of speed or
record status. The external event trigger characteristics are set in the ADV. SETUP - EXT. INPUT menu option.

If the recorder is triggered but not recording, the red LED will blink at a 1 second interval.

3.7 Status Line Indicators

The bottom line of the graphics LCD display is used to indicate the status of the display and of the recorder itself.
These status icons consist of reverse video characters or letters that appear according to operations performed and
are intended to prevent data on the display from being misinterpreted and to indicate the status of the alarms.

From left to right these icons are as follows:

- These icon symbols indicate that the alarms are enabled (1 is Alarm 1 etc.). Any number of them may be
present depending on how the alarms have been set up. If an alarm is enabled a solid block will be present. If the
alarm has exceeded the setpoint (i.e. is in an alarm condition) its symbol will be blinking.

- This symbol indicates that the external input is enabled. If the external input is triggered this symbol will blink.

- This symbol indicates the display is in the COMPRESSED mode. The amount of compression can be

determined from the time date stamps on the display. To exit from the Compressed Mode simply press the MENU
button.

- This symbol indicates the display is in the HOLD mode. The displayed data is no longer real time and will not
be updated. The Hold mode is entered by pressing either the LEFT or RIGHT arrow button, entering the
compressed mode, or viewing any internally buffered data.

- This symbol indicates the data on the display is from a FILE on the MEMORY CARD and not current data. To
view data from a file, use the MENU selection option "VIEW FILE". Note that if currently recording, viewing a file
does not disrupt the recording procedure provided that the file you are viewing is on the same memory card as the
one you are recording on OR you do not exceed the buffer storage time on the recorder if you are using another
memory card.

3.8 Entering Data

When adjusting or entering values you have to use the ▼▲►◄ button keys.

Alphanumeric Values – The ► key moves the cursor to the right to select the character to be edited. It will wrap
around from right to left. The ▼▲ change the character as shown in Appendix A. The MENU button accepts the
data and exits and the ◄ key escapes.

CF 151 17 AJW 10306 REV 1.0 05/07

Numeric Values – work a little differently; the value increments and decrements according to the up ▲ or ▼ down
keys. Single presses increment or decrement the value by 1. If the button is pressed and held down the value will
increment or decrement in steps of 10. If the MENU button is held down and the ▲ or ▼ button is pressed and held
down, the value increments or decrements by 100. The MENU button accepts the data and exits and the ◄ key
escapes.

5.0 MISCELLANEOUS

5.1 Battery Backup Option

If the recorder contains the Battery Backup Option, there is a toggle switch on the back panel below the terminal
block. The switch is marked ON and OFF.

In the OFF position, the battery is disconnected from the load and the recorder is off. The battery charges with the
switch OFF when the recorder is plugged into AC power.

In the ON position, with external power applied, the unit runs normally and automatically switches to battery backup
in the event of a power failure. The recorder continues to run from the battery until power is restored. If the battery
voltage reaches a preset low voltage threshold, the battery is automatically disconnected and the recorder shuts
off. When external power is restored, the unit starts up normally and the batteries begin to recharge. Likewise, the
unit can run off internal battery without external power by simply turning the unit ON. The recorder switch should be
turned OFF when not in use.

Additionally there is a procedure to turn the backlight off when the unit is running on battery. See Section 4.4. This
action extends the battery life and the unit continues to operate normally. The green power LED on the front panel
will blink when the recorder is being powered from the battery. Run times vary from 8 to more than 12 hours
depending on load conditions. It takes 10 to 14 hours for the battery to fully charge.

5.2 Ethernet Option

The Ethernet option is field installable and can be added to the recorder at any time PROVIDED there is no USB
option installed. The Ethernet and USB options are mutually exclusive. See Field Installation Instructions (Part
No. 1071-1256-110R) to add the Ethernet card to the recorder. If the product was ordered with the Ethernet option,
it will have been factory installed.

Setting the IP Address

The recorder needs to have the IP address set manually by the user. The address should be set so it is compatible
with the environment into which it connects.

To set the IP address:
Select MENU.
Using the ▲▼ buttons select ADV SETUP then COMMS.
Select IP ADDRESS then use the ▲▼►◄ keys to set an address. (►◄ selects which group of digits to adjust
then ▲▼ changes the number.) To accept the address, press the MENU button.

The IP address you set depends on how you plan to access the device. If you have a local connection, the IP
address needs to match the setting on your computer. The address will be in the form 192.168.0.210. Check your
computer’s IP Address then set the recorder address so that the first three sets of numbers match that of your
computer. The last digit should be different and should be unique – check with your IT department if you are
unsure.

Select SUBNET MASK and set it to 255.255.255.0, which is typical, or to whatever your system requires and then
press the MENU key. Use the ◄ key to exit the menu.

Connect the Ethernet cable to the recorder. There are two LEDs on the connector – one indicates connection, the
other indicates activity. Note that you cannot connect the recorder directly to your computer - you need to have a
hub or switch.

The connection can be tested by using the DOS Command Box and pinging the units. At the DOS prompt type:
Ping 192.168.0.210 (use the IP address you set).

CF 151 26 AJW 10306 REV 1.0 05/07

If the connection is good you will see a series of replies from the recorder. If you cannot connect, try pinging the
address with the recorder disconnected from the Ethernet. If you get a reply there is another device with that IP
address. Change the IP address on the recorder.

There are two methods of connecting to the recorder over the Ethernet – Browser connection and Navigator
Software.

Browser connection

Launch your browser (Internet Explorer preferred – V6 or later).
You need to ENABLE ACTIVE X and JAVASCRIPT. (From the browser toolbar, select TOOLS then INTERNET
OPTIONS then SECURITY. Select CUSTOM LEVEL and choose MEDIUM LOW or adjust the settings manually).

Enter the Recorder IP address into your browser and click GO. You should see a picture of the Recorder and the
data should update at a 3 to 5 second update rate depending on Ethernet traffic and recorder chart speed (slower
chart speeds will result in faster updates over the Ethernet.) Note that the browser shows the recorder status in real
time.

Navigator Software

The Navigator software enables the user to fully interact with the recorder over the Ethernet. You can alter settings,
stop and start recording, download data in real time for plotting or archiving on the PC, and you can download
historic data files.

Refer to the Navigator Software manual for additional information.

5.3 Calibration

Before leaving the factory, the recorder is calibrated using NIST traceable sources. The calibration values are
stored in non-volatile memory. The unit is calibrated to meet specification but the user may wish to re-calibrate the
unit, or calibrate specific input ranges for increased accuracy.

Calibration is the process of “fine tuning” each input for various differences that may arise due to manufacturing
processes, gain errors, temperature offsets and other physical parameters. Real analog to digital (A/D) converter
values are corrected by first adding an offset correction value, nominally zero, to the reading to correct for offsets
from zero, and then multiplying it by a span correction value that's nominally 1 to correct for gain errors.

Calibration setup can be found in the Channel x Setup Menu (x = A or B) under the ADVANCED SETUP menu
options. Each channel needs to be calibrated independently.

There are four options on the calibration menu:

CAL ZERO

adjusts the offset correction above or below actual 0 (zero), in steps equal to the resolution of
the A/D converter itself.

SPAN
NOMINAL

adjust a span correction value above or below actual 1, also in small amounts.
depending on the input range selected, either resets the correction values to 0 and 1, or copies
those values from the range it's a derived from. This usually affects only the input type category
selected for the current channel.

NOMINAL ALL

will reset all correction values for all input types on both channels when selected from any input
type and channel, a sort of master reset. This is the default in the event that calibration data is
found to be corrupted in the non-volatile memory.

5.3.1 Basic Calibration

All calibration values are derived from a couple of key calibration points. Thereafter, any fine-tuning done to a
specific input on a channel is saved for that channel and input range only. The key calibration constants are for:

CF 151 27 AJW 10306 REV 1.0 05/07

Lo Volts covering the 250mV, 1.25V, 2.50V ranges and should be done on the 250mV range – each

channel

Hi Volts covering the 5.00V, 12.5V, 25.0V ranges and should be done on the 5.00V range – each

channel

THERMOCOUPLES which are derived from the Lo Volts calibration value require an additional offset to

compensate for the ambient temperature sensor – each channel

RTDs which are derived from Lo Volts calibration value require an additional span calibration to

correct for the internal current source – each channel

CURRENTS which are derived from the Hi Volts calibration value require an additional span calibration to

correct for the external resistor (Customer supplied) – each channel

FREQ and SPEED requires only a time base calibration shared for both channels

In general, to calibrate an analog input, first set the specific channel to an input type in the ADVANCED SETUP
MENU - CHANNEL SETUP - INPUT TYPE (see Section 4.1). Once an input type has been chosen, select
CALIBRATION (see Section 4.1). Do not change the units from the default values set when that range is selected
(i.e. leave volts as volts and current as current).

Apply a "zero" value to the input and using the up (▲) and down (▼) arrow buttons adjust the OFFSET until the
onscreen indications shows zero.

Apply a "high" value to the same input and using the up (▲) and down (▼) arrow buttons adjust the SPAN until the
onscreen indication agrees with the input (Note – use an input value slightly less than the full scale value to prevent
an overrange indication).

Repeat for all input types and channels to be used, if not all of them.

5.3.2 Examples

Volts: Should be done for the Lo Volts - 250mV, 1.25V, 2.50V ranges, and Hi Volts - 5.00V, 12.5V, 25.0V ranges
using the 250mV and 5.00 volt ranges respectively. For each channel individually, set the input for 250mV and go
to Calibration. Short the input and adjust the OFFSET until 0 is indicated. Then apply a near full scale input (so as
to not over range the input, say 240 mV on the 250 mV range) and adjust the SPAN.

Thermocouples: (preferred method) First calibrate lo VOLTS range (250mV) for the same channel as described
above. Then switch to Thermocouple range. Select NOMINAL to copy the volts calibration to thermocouple range.
The recorder is now calibrated for ideal sensors. Refine the calibration by either shorting the input (you need to
know the ambient temperature) or attaching a thermocouple sensor or calibrator of the correct type for the selected
range, and then if necessary, adjust the OFFSET until the correct temperature is displayed – this corrects the
ambient temperature sensor. If there's a known "high" temperature source handy use that to fine-tune the SPAN
value.

Currents: (preferred method) First calibrate Hi VOLTS range (5.00V) for the same channel as described above.
Then switch to any CURRENT range. Select NOMINAL to copy the volts calibration to the current range. The
recorder is now calibrated for ideal resistor (250 ohm). Refine calibration for resistor and sensor current tolerances
by attaching a 250 ohm +0.1% resistor and input sensor matching the selected range. Apply low value inputs to
adjust the OFFSET value, and high value inputs to adjust the SPAN value.

RTDs: (preferred method) First calibrate lo VOLTS range (250mV) for the same channel as described above. Then
switch to RTD range. Select NOMINAL to copy the volts calibration to RTD range. The recorder is now calibrated
for ideal sensors and internal current source. Refine the calibration by applying an accurately known resistance for
a given temperature (you may need resistance to RTD tables). Adjust the SPAN until the correct temperature is
displayed – this corrects for the internal current source.

Frequency (RPM or Hz): Apply a calibrated frequency input near the high end of the selected input range of either
channel. Adjust SPAN until the indicated value is correct. There is no applicable OFFSET adjustment to be made.

Recommended procedure for full initial calibration, in this order:

- Calibrate 250 mV range, both channels using a calibrated source.

CF 151 28 AJW 10306 REV 1.0 05/07

- Calibrate 5.00 V range, both channels using a calibrated source

- Calibrate any T/C range, both channels using the NOMINAL method.

- Calibrate any RTD range, both channels using NOMINAL method

- Calibrate any current range, both channels using NOMINAL method

- Calibrate any Tach range, either channel using a calibrated signal source.

NOTES:

As with other numeric editing, the rate that a calibration value is adjusted accelerates with the length of time the
button is pressed.

Calibrating either channel for tachometry calibrates both channels and does not have to be repeated for each
channel as they use the same base counter. Additionally there's no OFFSET adjustment for these inputs.

Thermocouple and RTD linearization tables are very accurate; usually calibrating the 250mV range for the same
channel and then copying the calibration values using NOMINAL should be enough. Remaining sources of error
are the ambient sensor (probably small) for the thermocouple and the current source (small) for the RTD, and the
actual sensors themselves. The ambient sensor can be calibrated by adjusting the OFFSET with the thermocouple
at some known temperature (such as ice water) or a known room temperature with a wire short on the input. The
input sensor span adjustment would need a high temperature point to calibrate.

There can be interaction between the OFFSET and SPAN with the thermocouple input since it can't be easily
determined when exactly 0 volts is applied in combination from the ambient and input sensors. This can happen
with other input types where the input used for the OFFSET adjustment does not present 0 volts to the input.

Calibration values are copied to an EEPROM (non volatile) device when performing the calibration operations.
These values are copied from the EEPROM upon every power up of the recorder and tested for corruption. If the
values are found in error then nominal values are inserted in all categories.
