Safety and Regulatory Information
AC Mains Power Line Fuse
For continued protection against fire, replace the line fuse only with fuses of the specified type and rating.
The instrument must be disconnected from AC mains power, and all measurement terminals must be dis-
connected before changing the fuse.
Current Measurement Protection Fuse
For continued protection against fire, replace current-protection fuses only with fuses of the specified type
and rating. The instrument must be disconnected from AC mains power, and all measurement terminals
must be disconnected before changing the fuse.
Front/Rear Switch
Do not change the position of the Front/Rear switch on the front panel while signals are present on either
the front or rear set of terminals. The switch is not intended as an active multiplexer. Switching while cur-
rent or high voltage is present may cause instrument damage and lead to the risk of electric shock.
Do Not Operate in an Explosive Atmosphere or wet environments
Do not operate the instrument around flammable gases or fumes, vapor, or wet environments. The instru-
ment enclosure complies with the IP 20 rating.
In Case of Damage
An instrument that appears damaged or defective should be made inoperative and secured against unin-
tended operation until qualified service personnel can repair it.
Self-Test
Before measuring any hazardous voltage or current, remove all test leads to the instrument, run the
TEST:ALL? query from the remote interface, and read the result to verify that the instrument is performing
properly.
The TEST:ALL? 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 [Shift] > [Utility] > Test/Admin > Self Test
> Full Test. If this self-test fails, make sure that the instrument is repaired and passes the complete self-
test before continuing.
Measuring AC Power Mains
The HI, LO, and current input terminals may be connected to AC mains power in IEC Category II installations
for line voltages up to 300 VAC. To avoid the danger of electric shock, do not connect the inputs to AC
mains power for line voltages above 300 VAC. See
IEC Measurement Category II
for further information.
Measuring Current with A Current Transformer
If a current transformer is used for measuring current, you must use a current transformer with internal sec-
ondary protection. Using a current transformer without protection may result in a hazardous voltage res-
ulting in a severe shock or death. In addition, this may cause damage to the instrument.
Crest Factor
Exceeding the crest factor limit may result in an inaccurate or lower reading display. Do not exceed the
crest factor limit to avoid instrument damage and risk of electric shock. The crest factor limit is listed in the
product data sheet at www.keysight.com/find/truevolt-doc.
Measurement Limits
To avoid instrument damage and the risk of electric shock, do not exceed any of the Measurement Limits
defined in the following section.
