| 1. |
The pointer does not deflect.
(=Unable to measure.) |
|
Check the continuity of test leads.
If there is a break, replace the faulty test lead.
How to check: Set to the resistance range and short the test leads. |
|
|
| 2. |
When selecting Earth Voltage
range, the LED lights up although the test leads is not connected.
|
|
This is normal condition.
The LED is designed to light up at the Earth Voltage range in
order to avoid omitting to turn the switch to the OFF position.
|
|
|
| 3. |
At the earth resistance
ranges. Even though the prove is not connected, when the test
button is pressed the LED lights up and the pointer deflects to
the end. |
|
| This is not a fault. This operation is due to the
inner short-circuit. |
|
|
| 4. |
When measuring the earth
resistance, the OK lamp does not light up. |
|
Check if the test leads are firmly connected with
the unit.
If no, connect the test leads firmly to the tester.
Check if the test leads are firmly connected to
the earth spikes.
If no, connect the test leads firmly to the earth spikes.
Check if the part where the earth spikes are stuck
is enough moist.
If no, give enough water where the earth spikes are stuck.
Check the continuity of test leads.
If there is a break, replace the faulty test lead.
How to check: Set to the resistance range and short the test leads. |

| 5. |
The pointer moves abnormally. |
| |
 |
|
| The cover over the pointer may be electrized. Wipe
the cover with the cloth or apply the antistatic additives or
