Install the Batteries
Install the Batteries
Your multimeter is powered by four 1.5 V AAA alkaline batter-
ies (included with the shipment).
1 Turn the multimeter OFF and remove the test
leads from the terminals.
2 Loosen the screw on the battery cover with a
suitable Phillips screwdriver.
3 Remove the battery cover and observe the
polarity markings.
4 Insert the batteries and replace the battery
cover and screw.
Turn On the Multimeter
To power ON your multimeter,
turn the rotary switch to any
other position.
Controlling the Multimeter Remotely
Your multimeter is capable of
To PC (host)
remote data logging.
To use this feature, you will
need a PC running a Windows
operating system, an IR-USB
cable (U1173A, purchased sepa-
rately), and the Agilent GUI Data
Logger Software.
The Agilent GUI Data Logger software is downloadable for free
from www.agilent.com/find/hhTechLib.

Non-contact voltage detector (Vsense)
WA RN ING
Voltage could still be present even if there is no alert
indication. Do not rely on the Vsense detector with
shielded wire. Never touch live voltage or conductor
without the necessary insulation protection.
The Vsense detector may be affected by differences in
socket design, insulation thickness, and insulation type.
