:System frequency 50Hz
:None Battery system voltage 150V ~ 260V
: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.
