| 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. |
Unable to measure the current. |
|
|
Check the fuse for a break. If yes, change it to a new rated fuse as specified.
|
|
|
| 3. |
Unable to measure the resistance. |
|
Check the battery voltage.
If the voltage is low, change it to a new battery.
|
|
|
| 4. |
The pointer moves abnormally. |
| |
 |
|
The cover over the pointer may be electrized. Wipe the cover with the cloth or apply
the antistatic additives or the detergent diluted with water.
|
|
|
| 5. |
The pointer does not move to zero even by the zero ohm adjustment knob. |
| |
|
|
Check the battery voltage.
If the voltage is low, change it to a new battery.
The cover over the pointer may be electrized. Wipe the cover with the cloth or apply the antistatic additives or the detergent diluted with water.

 |
|
Check if the batteries are set appropriately.
Set the batteries propoerly.
Check if the battery is exhausted.
If yes, replace with new batteries.
|
|
|
| 7. |
The readings vary at the DC voltage range when the test is off. |
| |
|
|
This is normal condition.
DC value varies by the influence of noise.
|
|
|
| 8. |
The readings do not vary when the test is on. |
| |
|
|
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 circuit the test lead.
