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 specied 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 denes 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 denes 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 specied 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.

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 species 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 conguration 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 eect 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 eect.)
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 conrmation; 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.

3 Power Switch
4 USB Ports
5 Ethernet Port
6 Logic Signal Connector
7 Analog Inputs
8 Grounding Terminal
The inputs are capable of measuring500 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
dierence 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.
