AC voltage measurement refers to general commercial AC
voltage measurement
.
By determining
the difference between earthing
voltage, the meter can be used for testing below 600V AC line voltage.
As shown below: First
,
connect test wires
P
(S)
with
ES
interface
.
S
econd
,
connect test wires with tested line, then rotate
FUNCTION
rotar
y switch to “
EARTH VOLTAGE
” and start testing, LCD will display
the test results.

Earth Voltage Measurement
Earth voltage measurement
uses only 2 probes
(ES + P).
The meter connect
s
with the earth
by using only
testing wires and
2 probes
.
Other testing wires of meter’s
interface
cannot be used to
connect with commercial
power line L, N,
as breakers may be tripped and serious
damage to tester will result
.
Earth voltage measurement can
no
t exceed 600 V.
As shown below:
once
meter,
probes and
testing wires are all
connected, rotate
FUNCTION
rotary switch to “
EARTH
VOLTAGE
”
and start testing, LCD will display test results.
