Maintenance

 

WARNING: 

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

before removing the battery/fuse cover. 

 

WARNING:

 To avoid electric shock, do not operate your meter until the battery/fuse 

cover is 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. 

2. 

Use and store the meter in mild ambient conditions. Temperature extremes can 
shorten the life of the electronic parts and distort or melt plastic parts. 

3. 

Handle the meter gently. 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 Replacement 

WARNING

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

correct polarity. 

5. 

Replace the battery door and secure with the screw. 

 

Fuse Replacement 

WARNING

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

voltage before removing battery/fuse cover.

fast blow). 

8. 

Replace the fuse door and secure with the screw.
