Safety and Regulatory Information
Safety Considerations
The following general safety precautions must be observed during all phases of operation, service, and
repair of this instrument. Failure to comply with these precautions or with specific warnings elsewhere in
this manual violates safety standards of design, manufacture, intended use of the instrument, and could res-
ult in electrical shock or injury. Keysight Technologies assumes no liability for the customer's failure to com-
ply with these requirements.
Keysight DAQ970A User's Guide 9
Safety and Regulatory Information

BEFORE APPLYING POWER
Verify that all safety precautions are taken. Make all connections to the unit before applying power.
GROUNDTHEINSTRUMENT
This product is provided with protective earth terminals. To minimize shock hazard, the instrument
must be connected to the ac power mains through a grounded power cable, with the ground wire fam-
ily connected to an electrical ground (safety ground) at the protective (grounding) conductor. Dis-
connection of the protective earth terminal will cause a potential shock hazard that could result in
personal injury.
BEFORE POWER ON AND OFF
Before powering on the instrument, make sure all signal sources connected to modules are turned
off. Turn on signal sources after the instrument is powered on. Turn off signal sources before the
instrument is powered off.
DONOTREMOVETHEINSTRUMENTCOVER
Only qualified, service-trained personnel who are aware of the hazards involved should remove the
instrument covers. Always disconnect the power cable and any external circuits before removing the
instrument cover.
MODULE COVERS
Always replace module covers after terminal wiring and before inserting into mainframe.
DONOTOPERATEINAN EXPLOSIVEATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
DONOTMODIFYTHEINSTRUMENT
Do not install substitute parts or perform any unauthorized modification to the product. Return the
product to a Keysight Sales and Service Office for service and repair to ensure that safety features are
maintained.
DONOT MEASUREMORE THAN THE RATED VOLTAGE
Maximum voltage as marked on each module is as below:
a) DAQM900A: 120 Vrms
b) DAQM901A, DAQM902A, DAQM903A, DAQM904A, DAQM908A: 300 Vrms
c) DAQM905A, DAQM907A: 42 Vpk
DO NOT CONNECT ANY MODULE CHANNELS TO MAINS
Measurement category of the instrument is rated as CAT 'Others', terminals should not be directly con-
nected to the mains.
ACPOWERCORD
Removal of the AC power cord is the disconnect method to remove power from the instrument. Be
sure to allow for adequate access to the power cord to permit disconnection from ACpower. Use only
the Keysight specified power cord for the country of use or one with equivalent ratings.
Safety and Regulatory Information
10 Keysight DAQ970A User's Guide

SELF-TEST
Before measuring any hazardous voltage or current, run the *TST? query from the remote interface,
and read the result to verify that the instrument is performing properly. The *TST? query is a self-test
that returns +0 if the instrument passes and +1 if the instrument fails. You can also perform this
query from the front panel by pressing [Utility] >Self Test >Quick Test. If this self-test fails, make
sure that the instrument is repaired and passes the self-test before continuing.
INCASEOFDAMAGE
Instruments that appear damaged or defective should be made inoperative and secured against unin-
tended operation until they can be repaired by qualified service personnel.
This is a sensitive measurement apparatus by design and may have some performance loss when
exposed to ambient continuous electromagnetic phenomenon. Measurement Considerations – use
shielded or twisted cable, use common mode choke, ferrite clamp and damping resistor before the
input to DAQ970A.
CLEANING
To prevent electrical shock, disconnect the instrument from AC mains power before cleaning. Clean
the outside of the instrument using a soft, lint-free, cloth slightly dampened with water. Do not use
detergent or solvents. Do not attempt to clean internally. If needed, contact a Keysight Technologies
Sales and Service Office to arrange for proper cleaning to ensure that safety features and performance
are maintained.
Connect USB cable with ferrite core to the rear panel USB port of the instrument.
