5 Measurements
The content of this chapter should be thoroughly read and un-
derstood since it describes methods of measurements and basic
principles of interpreting measurement results.
5.1
Measurement of alternating voltage
(AC)
WARNING:
Electric shock hazard. The ends of measuring probes, due to
their length, may not reach the live parts inside some net-
work connections of low-voltage electrical equipment, be-
cause the contacts are arranged inside the sockets. In such
a case, the read-out will be 0 V with the simultaneous pres-
ence 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.
NOTE
Do not measure the voltage when an electric motor located
within the circuit is being switched on or off. Resulting volt-
age spikes may damage the meter.
To perform AC voltage measurement:
set the rotary switch at
,
shortly press
MODE
button, until symbol
AC
is shown on the dis-
play,
connect black test lead to
COM
terminal, and red test lead to
V
ΩHz%
mACAP
terminal,
contact the tips of test probes to the points of measurement,
read the measurement result on the display.
