Safety and Regulatory Information
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.
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.
USE THE DEVICE AS SPECIFIED
If the device is used in a manner not specified by manufacturer, the device protection may be impaired.
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/DAQ973A.
CLEANING
To prevent electrical shock, disconnect the instrument from AC mains power before cleaning. Clean the out-
side of the instrument with a soft, lint-free, slightly dampened cloth. Do not use detergent, volatile liquids, or
chemical 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.
