Cleaning
Periodically clean your meter’s case using a damp cloth. DO NOT use
abrasive, flammable liquids, cleaning solvents, or strong detergents as
they may damage the finish, impair safety, or affect the reliability of the
structural components.
Battery Replacement
Always use a fresh replacement battery of the specified size and type.
Immediately remove the old or weak battery from the meter and
dispose of it in accordance with your local disposal regulations. Batteries
can leak chemicals that corrode electronic circuits. If your meter is not
going to be used for a month or more, remove and store the battery in
a place that will not allow leakage to damage other materials.
To install a new battery, follow these procedures:
1. When the left corner of LCD display indicates “LO BAT”, it is time
to change the battery.
2. Remove battery cover and remove battery.
3. Replace with 9 V battery and reinstall battery cover.
WARNING!
Under no circumstances should you expose batteries to extreme heat or
fire as they may expose and cause injury.
