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.
