Trouble Shooting; Battery Replacement - Amprobe VPC-30 Mode D'emploi

Trouble Shooting

If the tester fails to operate, check batteries, probes, etc., and replace as
necessary. Double check operating procedure as described in this user's manual
If the tester voltage-continuity input has subjected to high voltage transient
(mostly caused by lightning or switching surge to your system) by accident or
abnormal conditions of operation, the series fusible resistors will be blown
off (become high impedance) like fuses to protect the user and the tester.
Most measuring functions through this input will then be open circuit. The
series fusible resistors and the spark gaps should then be replaced by qualified
technician. Refer to the LIMITED WARRANTY section for obtaining warranty or
repairing service.

Battery replacement

The batteries should be checked before use. When the battery voltage is low,
the , +L, -L or K LED flashes under normal significant measurements. VPC-
31 also displays low battery icon N on the LCD under normal significant
measurements. Replace the batteries ASAP to maintain tester accuracy and
functionality. The tester uses two 1.5V batteries: Standard 1.5V AAA Size
(NEDA 24G or IEC R03) battery X 2; or 1.5V AAA Size (NEDA 24A or IEC LR03)
alkaline battery X 2.
