Safety Considerations
Read the information below before using this instrument.
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 for design, manufacture, and intended use of the instrument. Keysight
Technologies assumes no liability for the customer’s failure to comply with these
requirements.
WARNING BEFORE APPLYING POWER
Verify that all safety precautions are taken. Make all connections to the unit
before applying power.
WARNING 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 family connected to an
electrical ground (safety ground) at the protective (grounding) conductor.
Disconnection of the protective earth terminal will cause a potential shock
hazard that could result in personal injury.
WARNING 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.
WARNING 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.
Keysight DAQ970A/DAQ973A Service Guide 5
WARNING MODULE COVERS
Always reinstall module covers after terminal wiring and before inserting
into mainframe.
WARNING DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
WARNING 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.
WARNING DO NOT MEASURE MORE THAN THE RATED VOLTAGE
Maximum voltage as marked on each module is as below:
– DAQM900A: 120 Vrms
– DAQM901A, DAQM902A, DAQM903A, DAQM904A, DAQM908A: 300 Vrms
– DAQM905A, DAQM907A: 42 Vpk
– DAQM909A: +/-18Vpk (single ended) for both HI and LO pins.
WARNING DO NOT CONNECT ANY MODULE CHANNELS TO MAINS
Measurement category of the instrument is rated as CAT 'Others', terminals
should not be directly connected to the mains.
6 Keysight DAQ970A/DAQ973A Service Guide
WARNING 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.
WARNING 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.
WARNING IN CASE OF DAMAGE
Instruments that appear damaged or defective should be made inoperative
and secured against unintended operation until they can be repaired by
qualified service personnel.
CAUTION MEASUREMENT CONSIDERATIONS
This is a sensitive measurement apparatus by design and may have some
performance loss when exposed to ambient continuous electromagnetic
phenomenon. Consider using shielded or twisted cables, common mode
chokes, ferrite clamps, and damping resistors before the input to the
DAQ970A/DAQ973A.

CAUTION 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.
