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. 

BATTERY INSTALLATION 

WARNING

: To avoid electric shock, disconnect the test leads from any source of voltage 

before removing the battery cover. 

1. Turn power off and disconnect the test leads from the meter. 
2. Open the rear battery cover by removing two screws (B) using a Phillips head 

screwdriver. 

3. Insert the battery into battery holder, observing the correct polarity. 
4. Put the battery cover back in place. Secure with the screws. 

WARNING: 

To avoid electric shock, do not operate the meter until the battery cover is in 

place and fastened securely. 

NOTE:

 If your meter does not work properly, check the fuses and batteries to make sure that 

they are still good and that they are properly inserted.
