Maintenance                                                                                           

WARNING

:  To avoid electric shock, disconnect the test leads from 

any source of voltage before removing the back cover or the battery 
or fuse covers. 

 

WARNING: 

To avoid electric shock, do not operate your meter until 

the battery and fuse covers are in place and fastened securely. 

This MultiMeter is designed to provide years of dependable service, if 
the following care instructions are performed: 

1. 

KEEP THE METER DRY

. If it gets wet, wipe it off. 

2. 

USE AND STORE THE METER IN NORMAL TEMPERATURES.

 

Temperature extremes can shorten the life of the electronic parts 
and distort or melt plastic parts. 

3. 

HANDLE THE METER GENTLY AND CAREFULLY.

 Dropping it 

can damage the electronic parts or the case. 

4. 

KEEP THE METER CLEAN.

 Wipe the case occasionally with a 

damp cloth. DO NOT use chemicals, cleaning solvents, or 
detergents. 

5. 

USE ONLY FRESH BATTERIES OF THE RECOMMENDED 
SIZE AND TYPE. 

Remove old or weak batteries so they do not 

leak and damage the unit. 

6. 

IF THE METER IS TO BE STORED FOR A LONG PERIOD OF 
TIME

, the batteries should be removed to prevent damage to the 

unit.
