MAINTENANCE
This section provides basic information about how to care for the digital multimeter and replace the
battery and fuses.
WARNING!
Do not attempt to repair or service the digital multimeter unless you are qualified to do so and
have the relevant equipment for testing and calibration and other service information. To protect against
electric shock, never allow water to enter the casing.
General care
Wipe the outside of the instrument regularly with a soft cloth and mild detergent. Do not use
solvents or abrasive products for cleaning.
Clean the terminals with a cotton swab slightly dampened with a mild detergent as dirt and
moisture can produce inaccurate readings.
Turn off the multimeter after use and remove the battery if you are not going to use the instrument
for a longer period of time.
Do not store the instrument at high temperatures, high air humidity or around strong magnetic
fields.

replace the battery as soon as
