(Tests, continued)
RM – Reverse Mains Test
This test will break both the Live/L1 and Neutral/L2 power lines to the DUT. It will
then reverse the normal connection, so that what was Live/L1 is now Neutral/L2,
and what was Neutral/L2 is now Live/L1. To choose Reverse Mains measurements
when the selection is available, press the
rev. pol
button. The display will reflect
the change in measurement type.
⇒
Warning!
When testing units that have a large inductive load (motor),
always turn OFF the DUT
BEFORE
reversing Mains.
Mains Voltage Test – “V”
This test measures the mains voltage, in volts,
between Live and Neutral. Press the
V
button below
the
line voltage
label, and the result will be
displayed.
Protective Earth Test – “
m
Ω
”
This test measures the resistance, in milliohms,
between the enclosure of the DUT and Earth contact
on the front outlet. To execute the test and display
the results, connect the test lead to the enclosure of the DUT, and then press the
m
Ω
button below the
gnd wire res
label.
Earth Leakage Current Test – “
µ
A” – ON, RM
This test measures the current, in microamps,
passing through the Earth lead. To execute the test
and display the results, press the
earth
button below
the
leakage current
label.
⇒
Warning!
When testing units that have a large inductive load (motor),
always turn OFF the DUT
BEFORE
reversing Mains.
Enclosure Leakage Current Test – “
µ
A” – OE,
ON, RM, OERM, ONRM
This test measures the leakage current, in
microamps, between the enclosure of the DUT and
Earth contact on the front outlet. To execute the test and display the results, connect
the test lead to the enclosure of the DUT, and then press the
enclosure
button
below the
leakage current
label.

Warning!
When testing units that have a large inductive load (motor),
always turn OFF the DUT
BEFORE
reversing Mains.
