Over Temperature
Protection
When overheating,the ” ” symbol
will show on the LCD, and the 8025LP
stop measuring.
Wiring check
P-E LEDs illuminate when the
wiring polarity of circuit under
P-N test is correct
N-E
LED is light when P and N are
reversed or the Earth is not
connected.
15mA Loop
measurement
Loop impedance 2000Ω range
measurement is carried out with low
test current (15mA).
The current will not cause tripping
out for ELCBs.
