INSTRUCTIONS
1. Display
2. "TEST" button
This button can be used to Start or stop grounding resistance fest alter you switch the fester an and
set the FuncbonlRange to a resistance Tange. After you press this button, hie grounding resistance fest
begins. Ahout 30 seconds later, the test automatically stups. If you want to stop the fest ahead of time, just
press this button again.
3. "LOCK" key (for continuous grounding resistance test)
After you press this key when the grounding resistance fast is on, "LOCK" appears on the display,
and the grounding resistance test will last until you press TEST buttan again.
4. "HOLD" key
To hold the present reading, just press this key and " appears as an indication. To exit Data Hold
mode, press this key again.
5. "*"key
Press this key to enable the backlight function. About 15 seconds later, the backlight will go off
automatically
6. Function / Range switch
This switch can be used to tum onloff the tester as well as to select desired Tange or function.
7. LED
After you press the "TEST" Button with the function/range switch in a resistance range, the LED lights
to indicate that the grounding resistance test circuit is working. If the LED gives green light, it means that the
tester is working normally. If the LED gives red light, it means the resistance between "C" terminal and "E"
terminal is out of the permitted range.
8. "C" terminal
lt is a current terminal for grounding resistance test. lt is to be connected to the auxiliary earth bar
which is farther away from the earth electrode to be tested in normal grounding resistance fest (refer to Figure
2 ).
9. "P" terminal
lt is a voltage terminal for grounding resistance fest, lt is to be connected to the auxiliary earth bar
which is nearer to the earth electrode to be tested in normal grounding resistance fest. (refer to Figure 2 )
10. "E" terminal
In grounding voltage test, it is a common terminal.
In grounding resistance fest, it is to be connected ta the earth electrode to be tested,
11. 'V" terminal lt is a input terminal for grounding voltage fest.
