Safety Summary

The following safety precautions apply to both operating and maintenance personnel and must be followed during all
phases of operation, service, and repair of this instrument.

Before applying power to this instrument:

 Read and understand the safety and operational information in this manual.
 Apply all the listed safety precautions.
 Verify that the voltage selector at the line power cord input is set to the correct line voltage. Operating the instrument

at an incorrect line voltage will void the warranty.

 Make all connections to the instrument before applying power.
 Do not operate the instrument in ways not specied by this manual or by B&K Precision.

Failure to comply with these precautions or with warnings elsewhere in this manual violates the safety standards of design,
manufacture, and intended use of the instrument. B&K Precision assumes no liability for a customer’s failure to comply
with these requirements.

Category rating

The IEC 61010 standard denes safety category ratings that specify the amount of electrical energy available and the
voltage impulses that may occur on electrical conductors associated with these category ratings. The category rating is
a Roman numeral of I, II, III, or IV. This rating is also accompanied by a maximum voltage of the circuit to be tested,
which denes the voltage impulses expected and required insulation clearances. These categories are:

Category I (CAT I): Measurement instruments whose measurement inputs are not intended to be connected to the

mains supply. The voltages in the environment are typically derived from a limited-energy trans­former or a battery.

Category II (CAT II): Measurement instruments whose measurement inputs are meant to be connected to the mains

supply at a standard wall outlet or similar sources. Example measurement environments are portable
tools and household appliances.

Category III (CAT III): Measurement instruments whose measurement inputs are meant to be connected to the mains

installation of a building. Examples are measurements inside a building’s circuit breaker panel
or the wiring of permanently-installed motors.

Category IV (CAT IV): Measurement instruments whose measurement inputs are meant to be connected to the primary

power entering a building or other outdoor wiring.

Do not use this instrument in an electrical environment with a higher category rating than what is specied in this manual
for this instrument.

You must ensure that each accessory you use with this instrument has a category rating equal to or higher than the
instrument’s category rating to maintain the instrument’s category rating. Failure to do so will lower the category rating
of the measuring system.

Electrical Power

This instrument is intended to be powered from a CATEGORY II mains power environment. The mains power should be
115 V RMS or 230 V RMS. Use only the power cord supplied with the instrument and ensure it is appropriate for your
country of use.

Ground the Instrument

To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical safety ground. This
instrument is grounded through the ground conductor of the supplied, three-conductor AC line power cable. The power
cable must be plugged into an approved three-conductor electrical outlet. The power jack and mating plug of the power
cable meet IEC safety standards.

Do not alter or defeat the ground connection. Without the safety ground connection, all accessible conductive parts
(including control knobs) may provide an electric shock. Failure to use a properly-grounded approved outlet and the
recommended three-conductor AC line power cable may result in injury or death.

Unless otherwise stated, a ground connection on the instrument’s front or rear panel is for a reference of potential only
and is not to be used as a safety ground. Do not operate in an explosive or ammable atmosphere.

Do not operate the instrument in the presence of ammable gases or vapors, fumes, or nely-divided particulates.

The instrument is designed to be used in oce-type indoor environments. Do not operate the instrument

 In the presence of noxious, corrosive, or ammable fumes, gases, vapors, chemicals, or nely-divided particulates.
 In relative humidity conditions outside the instrument’s specications.
 In environments where there is a danger of any liquid being spilled on the instrument or where any liquid can condense

on the instrument.

 In air temperatures exceeding the specied operating temperatures.
 In atmospheric pressures outside the specied altitude limits or where the surrounding gas is not air.

Getting Started

You turn on the recorder by pressing the button at the top of the device.
When the device is on, the ON/OFF button is lit blue.
After launching the software, the recorder displays a homepage that species the hardware version, then switches auto­matically to the « Direct display » mode (oscilloscope).

You can display this homepage any time in the main menu by pressing
To turn o the device, you only have to press the ON/OFF button twice.
If the device does not stop correctly, you must press the power button for 5 seconds and the recorder will shut o; in this
case, the instrument conguration will not be saved.

2.1 Measurement Types

Voltage The voltage is measured between the red and black terminals of the inputs with wires and male

security pin plugs (according to CEI 1010).

Thermocouple Temp The voltage resulting from thermocouple eect must be measured between the red and black ter-

minals of the relevant input. To provide right measure values, connect the two ends of the ther­mocouple cord directly onto the quick fastening socket. Plug the two pin plugs onto the selected
input with respect of the polarity. (Do not use welding male pin plugs: the welding would alter
the thermocouple eect.)

Platinum RTD The Pt100 probe must be connected on the « I+ » and « I- » terminals.

The voltage from the Pt100 must be measured between the « + » and « -» terminals with one
of the two following mountings: 2, 3 or 4 wires. The 3 or 4-wire mountings make the measure­ment independent from the resistance of the line.

.

Current You can make current measurements by shunt between the red and black terminals of the rel-

evant input.
In this case, select the "current" type among the parameters of the relevant channel. Connect
the measurement wires to the terminals of the shunt.
The results are directly displayed in Amperes or milliamperes according to the caliber of the se­lected channel.

Logic Using the Logic input (25 pin connector) digital signals can included in the recording or used as

triggers. The logic connector also includes pins that can be used as output signals (alarms) for
other equipment. Up to 16 signals are available for recording and triggering and 4 signals for alarm
outputs.

2.2 Powering the Recorder

Each recorder includes an internal rechargeable Lithium-Ion battery. The recorder is powered and charged by a 15 V 4
A charger. The charger included with the recorder is powered by 100-240 VAC at 50-60 Hz. The recorder runs with or
without the power supply connected and provides up to 8 hours of power when running on battery. When the power
supply is connected a green LED lights beside the 25-pin logic input connector.
To turn on the recorder, press the button labeled “ON/OFF” located on the top surface of the recorder. When on, the
ring around the button lights up blue. Battery charge state is shown on the front screen.
To turn o the recorder press the power button. A window will appear on-screen prompting for conrmation; press the
green “Check Mark” to shut down the recorder. If the red “X” is pressed or if the green “check mark” is not pressed
within 10 seconds, the recorder will not turn o.

8 Grounding Terminal

The inputs are capable of measuring500 VDC or 440 VAC.

For best results and to eliminate noise, twisting or shielding the leads is recommended. If the source of the signal you
have to record has low internal impedance, use twisted wires. For high impedance signal sources, using shielded wires
is recommended.

When gathering grounds from the various items on the measurement line, it is good to check that there is no voltage
dierence between them, in order to prevent any shortcut. If any doubt, make a measurement with a voltmeter on a

low resistance (i.e. 1k) between the terminals.

2.4 Ground the Recorder

For safety, the unit should be connected to Earth ground. The recorder includes a terminal for this purpose located on
the top surface of the DAS60 and on the right-hand side of the DAS30 and DAS50.

« Impossible » shows up when there is not enough place for saving data: you should reduce the sampling rate

or the number of channels

See chapter File mode to know the restrictions of the recording on le.

7.2 Sampling period

When the frequency of the input signals is too high to record them in Direct mode, you must record the measurement
signals into memory at high sampling rate: it is the Memory mode.
Sampling consists in recording the instant value of a signal at regular intervals and storing each of these values into a
memory.
To get adequate acquisition of a periodic signal, you need to choose a sampling period compatible with the frequency of
the signals present at the input terminals of the recorder.

A 10-dot per signal period denition is minimal for a satisfactory plot.

7.3 Internal memory, blocks

The available memory in the recorder can be shared into blocks that will be lled one after the other at each data
acquisition.
The acquisition depth is worth N / (B * V)
N= total memory amount
B = number of blocks
V = number of channels to scan
Example: memory 32 Mwords, 16 blocks and 3 channels ’ON’, we shall have: N = 32 554 432 / (16 * 3)= 699 050
words/channel.
Any new data acquisition goes automatically into the rst free block (in increasing order).

37

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

When all blocks are full, any new data acquisition will shift the previous blocks from the N position into the N-1 position;
the 1stblock will be lost.
The new data acquisition will take the place of the last block.

7.4 Trigger position

The data acquisition into a memory block relies on the concept of « circular buer »:

 the buer is lled from the starting condition on
 the buer is lled as long as the stop condition is not valid; when the buer is full, it lls from the initial position of

the buer zone (block)

Thus, the memory block always contains the last N samples.
The operator can select when the samples in buer will be frozen; to do so, you will select a delay between the trigger
start and the beginning of the eective buering.
This delay may be positive or negative: thus, buered samples may be before, after or on both sides of the start moment.
You can also not inhibit the trigger: you will be able to test the trigger during the pre-trigger phase, in case the trigger
should happen before the end of this phase. In case of repetitive signals, the trigger should be inhibited.
Delay to memory input: -50% Delay to memory input: +50% from the 1stposition of buer from the 1stposition of
buer

7.5 Double Trigger mode

In this mode, you will use a start trigger and a stop trigger.
Measurements between these two triggers shall be registered.
Data acquisition will stop automatically: - when the stop condition is valid, or - when the memory block is full.

8.1 Restrictions

Real time data acquisitions to a le are limited by the transfer rate between the inputs and the saving means of the
internal memory or USB sticks.
It is advisable no to create too big les, because reading them may be very long. It takes ca. 3 minutes to read a 200MB
le.
The minimum transfer rate to the ash disk is 100 Kwords/s (10µs)
To know the number of channels you can record at a given acquisition period, calculate:
number of channels = 100 000 x acquisition period example: at 20µs, the number of channels is max. 2.

Go/No Go Mode

This chapter describes the “Go/No Go” designed to record in real time the measurement data made on the channels into
the internal memory.
You can start the data acquisition under various conditions It stops when the measurement values go out of a range
dened by a previous data acquisition called Template.
A simultaneous save of the measurements onto a le can be activated.

9.1 Setup and launching of the data acquisition

The comparison to the template is only possible when the channels are validated for data acquisition. An error

message shows up if you have selected « Template Channels » that have note been validated.

The data acquisition is made as above (see chapter Memory Mode).
When the memory block is full, the device checks that all measured points on the template channels are between the 2
min. and max. reference curves constituting the template.
If all points are between the curves, the data acquisition restarts (in the same block). If not, the data acquisition stops.

You can also check if the wiring is right by displaying the Fresnel diagram. The length of the arrows is not proportional
to the ecient value of the currents: the user will have to check that what he sees is coherent.
The position of the voltage arrows is calculated with reference to the voltage V1.
Attention: the angles are those of the voltages/currents representative either of the shape factor or of the fundamental
values.
You can check whether the connection is direct or reverse. Intensity vectors are calculated in reference to the corresponding
voltages.

Attention: even if nothing abnormal appears, there may be mistakes. In any case, the wirings must be made

with caution by a qualied personal.

10.5 Warning messages

Messages may appear in red any time at the top of the screen:

 Impossible to synchronize the signal: the frequency is wrong, the signal is too weak or too noisy
 Caliber exceeded: The voltage or the current are too high for the theoretical nominal value: you must change this

value or use another probe.

10.6 Recording additional channels

You can record additional channels by checking channels to record in the setup of your network analysis. The number of
channels will change as a function of the network (single phase: more additional channels, three phases: less additional
channels):

 the « triggers » menu, with the start and stop parameters of the recording.
 Edge/Level trigger

 Edge trigger: you need a change of status o Example: Channel A1, rising edge, threshold = 0V: triggers only if

the signal status changes from negative to positive

 Level trigger: no need to pass the threshold o Example: Channel A1, high level, threshold = 0V: triggers only if

the signal is positive

 Alarms only have level triggers.

 Analog / Logic channels: trigger only from analogic or logic channels
 Single / Multiple threshold:

 triggering from only one threshold, or
 complex triggering from several channels and several thresholds; see description below.

Such complex triggering is only possible with analogic channels.
You can setup these triggers thanks to the « trigger » menu in the homepage.

Figure 14.2 Logic Input

Non-connected inputs are 0V potential (level 0).
Number of logic channels: from 1 to 16.
TTL level: 3.3V (protected up to 24V)
To create a rising edge, you only have to place a connection between the power input and output of the connector.
Similarly, to create a falling edge, you only have to remove this connection. You can also use an output signal TTL 3.3V.

14.2.1 Use

Plotting and display:

These channels are plotted on the right or left side of the paper according to the selected format.
They are displayed at the top or the bottom of the screen according to the selected position.
They are numbered from the right to the left.
Each channel is plotted between two dotted lines that show their limits. The height of reticules is min. 2mm for the plot.

External clock:

You can use the logic channel 16 (see gure "connector") as a data acquisition clock for the sampling in memory or le
mode. The data acquisition can then be made up to 500kHz.

Triggers:

You can use the logic channels to trigger the plotting and the data acquisitions (start and stop).

Programming

16.1 Message Format

Note: In all the following examples, the space character is pictured as a blank space.

Exchanges from a controller to the recorder are made as messages made of a chain of ASCII characters (and possibly of
binary bytes) with a message termination at the end.

16.2 Response Format

Messages are terminated by a termination character. Messages may include multiple commands. If the message includes
several message units, they are separated with a semicolon ";" and possibly preceded and/or followed by one or several
"lling" characters in ASCII code (0 to 32, in decimal format except 10 and 13).

Termination Character LF

The message termination may be preceded with one or several "lling" characters under ASCII code (0 to 32, in decimal
format except 10 and 13).
Example of messages made with 3 message units:

MESSAGE 1; MESSAGE 2 ; MESSAGE 3 { TERM}

CHANNEL 1; TYPE:VOLTAGE DC;:CALDEC ? { TERM}

16.3 Message Syntax

A message (ex. :REAR:SETUP 1) is made of several elds:

16.3.1 Header

For the command messages (ex. :REAR:SETUP 1) or query messages (ex. :REAR ?), it is made of a chain of characters
(simple header) or several chains separated by ":" (compound header). A chain includes from 1 to 12 alphanumeric
characters or "_" (code ASCII 95 in decimal format). The recommended chain length is 4 characters.
A header chain always starts with an alphabetic character. It may be preceded by a colon ":" (compound header) or end
by a question mark "?" (query message).

Note: Query messages must be followed by the termination.

16.3.2 Header separator

One or several ASCII characters (0 to 32, decimal except 10 and 13).

16.3.3 One or several pieces of data

(ex. :SPEED 1,MM_S), alphanumeric, digital or compound of various characters or binary bytes.

16.3.4 Data separator

A comma "," possibly followed and/or preceded by one or several "lling" characters in ASCII code (0 to 32, decimal
except 10 and 13).

16.3.5 Data

There are several types of data:

16.3.5.1 Alphanumeric data

1 to 12-character words that can be alphabetic (upper case or lower case), digital or "_" (95d) coded under ASCII.
Words always start with an alphabetic character.
For example, for a non-digital parameter: S1M.

16.3.5.2 Decimal digital data

Made of a mantissa and possibly of an exponent, and shown as a chain of ASCII characters starting with a cipher or a
sign (+ or -). They are of NR1 (integer), NR2 (decimal) or NR3 type (with exponent) or of a combination of these three
types.

16.3.5.3 Text

Any chain of ASCII 7-bit characters between brackets (") or apostrophes (’). Example: "Channel 1"

16.4 Message Response Format

Exchanges from a recorder to a controller to the recorder are made as messages made of a chain of ASCII characters
(and possibly of binary bytes) with a message termination at the end.
The format of emission messages is identical to the reception messages, although with a more rigid structure.
The syntax of a response message is: Message unit + message termination.

Message unit If the message includes several message units, they shall be separated by a semicolon ";".

Message termination LF: Line Feed (10 in decimal format)

16.4.1 Syntax

A message unit (ex. TYP:THE J,COMP) is made of several elds:

16.4.1.1 Single Header

(ex.TYP:THE) made of only one (simple header) or several (compounds header) chains of 1 to 12 alphanumeric
characters (upper scale only or digital or "_" (code ASCII 95 in decimal format).
A header chain always starts with an alphabetic character.
In a compound header, chains of characters are separated by ":" (ex. TYP:THE).

Header separator "space" (32d) only.

One or several pieces of data (ex. J,COMP) alphanumeric, digital or compounds of any characters or binary bytes.

79
