Do not block the primary disconnect
The primary disconnect device is the appliance connector/power cord when a
chassis used by itself, but when installed into a rack or system the disconnect
may be impaired and must be considered part of the installation.
Do not modify the instrument
Do not install substitute parts or perform any unauthorized modification to the
product. Return the product to an Keysight Sales and Service Office to ensure that
safety features are maintained.
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.
WARNING
– IEC Measurement Category II. The HI and LO input terminals may be
connected to mains 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 mains for line voltages above 300 VAC. The M9181A DMM is limited to
240 VAC. See
IEC Measurement Category II overvoltage protection
for further information.
– The DMM comes installed with four shields (bottom, top and two edge
strips). These shields must be in place for performance and safety
reasons. Removal or improper assembly of these shields can result in
lethal voltages occurring within your PC. Be sure to check your
installation before closing the cover on your chassis.
