6) MEASURING METHODS
1) Battery Voltage Check
a. Before testing, press the "ON/OFF" button, when the
"Battery : Low" appears or the display, replace with new
batteries.
b. Prior to measuring, If "Battery : Low" appears on the display,
replace with new batteries
2) Earth Voltage Check
a. Test leads connection.
b. Press the "ON/OFF" button, "ACV" button and
"TEST/STOP" button, earth voltage will be displayed
on the LCM. When the earth voltage is more than 10V
It may result in errors in earth resistance measurement.
Make sure that the indicated value is less than 10V
3) Earth resistance measurement
The measured results may be influenced by induction
if measurement are made with the test leads twisted
or connected each other. When connecting the Probes,
they should be separated.

c. Press "TEST/STOP" button to test and take a reading
=When you make the "4P measurement", LCD Shows
"Vp Error", Short Circuit C1 (Black) and P1 (green).
=Stick the three Auxiliary Earth spikes into the ground
deeply. The distance must be 5 ~ 10m between the
Auxiliary Earth Spikes.

=Cleaning And Storage :
8) MAINTENANCE
WARNING
Do not mix new and old batteries together.
=Battery Replacement :- When the Battery "Low" appears on
the display, replace the batteries as follows :
1) Disconnect the test leads from the instrument and remove the
battery cover and the batteries.
2) The tester's battery is situated under the tester.
3) Replace with eight 1.5V AA light batteries, taking care to
observe correct polarity.
4) Reinstall battery holder and the battery cover.
WARNING
To avoid electrical shock or damage to the
meter, do not get water inside the case..
Periodically wipe the case with a damp cloth and detergent :
do not use abrasives or solvents.
09
Notes :
Check the following prior to proceeding with measurement:
1) Checking if Auxiliary Earth Spikes connect correctly when
the "RC" LED lit.
2) Indication for "Rc" & Rp"
Rc : When the "Rc" LED lit, this means there is no test current
output.
Rp : When the "Rp" LED is lit, the "R" value on the LCD
will displayed "> 2kW", this means testing Earth resistance
value is over 2kW.
7) FUSE REPLACEMENT
WARNING
Only replace with the same fuse specification
1) Disconnect the test leads from the instrument.
2) The fuse is located under the battery holder.
3) Open the battery cover. then remove and replace the fuse
with the new one.
4) Fix the cover after replacing a fuse and screw up the
cover. Fuse Spec. 0.1A / 250V, 5 x 20mm
Fuse (0.1A / 250V)
