1
Press the Power button to turn it
on.
2
Press the 3P/2P button to display
(3-pole method).
Earth potential appears on the display.
3
Press the MEASURE button.
Automatically executes the earth potential
check→auxiliary earth resistance
check→earth resistance measurement in
sequence.
The measurements will be completed in
approx. 6 s, and then the measured value
appears and lights up.
4
Check the measured value.
The displayed parameter can be changed after measurement.
Press the Fn button to switch parameters.
When NOISE appears
If the earth potential is high (25 V rms or 35.4 V peak or higher),
and the earth potential peak value appears on the display.
When is on, or when (live wire warning LED) is blinking,
it is not possible to measure earth resistance.
Since leak current is flowing into the earthing electrode, first
disconnect any electric equipment connected to the earthing electrode
and then press the
MEASURE
button again.
• The instrument automatically detects AC/DC ( / ) of the earth
potential.
If AC/DC needs to be switched, it can be switched by pressing the
Fn
button
while the current earth potential has been displayed.
