5.3 Voltage measurement
WARNING

Electric shock hazard. The ends of measuring
probes, due to their length, may not reach the live
parts inside some network connections of low-
voltage electrical equipment, because the contacts
are arranged inside the sockets. In such a case, the
read-out will be 0 V with the simultaneous presence
of voltage in the socket.

Before acknowledging the absence of voltage in the
socket make sure that the ends of the of the probe
touch the metal contacts inside the socket.
CAUTION!
Do not measure the voltage when an electric motor lo-
cated within the circuit is being switched on or off. Re-
sulting voltage spikes may damage the meter.
To perform AC voltage measurement:

set the rotary switch at V Hz or mV ,

press MODE button to display the following symbol:

, if an alternating voltage is to be measured,

, if a constant voltage is to be measured,

connect black test lead to COM terminal, and red test lead to
V
Ω
Hz%CAPTemp terminal,

contact the tips of test probes to the points of measurement,

read the measurement result on the display.
