Safety Summary
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 may impair the protections provided
by the instrument. In addition, it violates safety standards of design, manufacture, and
intended use of the instrument. Keysight Technologies, Inc. assumes no liability for
customer’s failure to comply with these requirements.
Product manuals may be provided on CD-ROM or in printed form. Printed manuals are
an option for many products. Manuals may also be available on the Web.
NOTE Do not use this instrument in any manner not specified by the manufacturer. The
protective features of this instrument may be impaired if it is used in a manner not
specified in the operation instructions.
This instrument is an INDOOR USE product.
This instrument complies with INSTALLATION CATEGORY II for mains input and
INSTALLATION CATEGORY I for measurement input terminals, and POLLUTION DEGREE 2
defined in IEC 61010-1.
If an instrument is marked CAT I (IEC Measurement Category I), or it is not marked with a
measurement category, its measurement terminals must not be connected to
line-voltage mains.
Safety of any system incorporating the equipment is the responsibility of the assembler of
the system.
WARNING Hazardous voltage, instrument maximum output voltage may appear at the measurement
terminals (High, Force, Guard, and Sense) if Interlock terminal is closed. Open the
Interlock terminal when the measurement terminals are accessible. Voltage applied to
the terminals will be limited up to ±42 V.
Do not work the interlock function intentionally in order to bring the output voltage to the
safe level. While the high voltage indicator is lit, the dangerous voltage by the output
voltage or the residual charge appears on the measurement terminal.
