| 12. |
Unable to measure the resistance. |
|
Check the battery voltage. If the voltage is low,
replace the batteries.
Change it to a new battery. |

| 18. |
When the range is set to
DC voltage, the readings vary although measuring nothing. |
| |
|
|
This is normal condition.
DC value varies by the influence of noise. |
