14 Cleaning and maintenance

14.1 General information

The multimeter should be calibrated once a year to ensure that measurements
remain accurate.
The multimeter does not need to be serviced (apart from occasional cleaning
and battery/fuse replacements).
Refer to the following sections for instructions on how to change the fuse and
battery.
Regularly check the device and test leads for signs of damage.

14.2 Cleaning

Always observe the following safety instructions before cleaning the device:
Opening covers on the product or removing parts that cannot be removed
by hand may expose voltage-carrying components.
Before cleaning or servicing the multimeter, disconnect all cables from
the multimeter and measured objects, and then switch the multimeter off.
Do not use abrasive detergents, petrol, alcohol or other similar chemicals to
clean the device. These may corrode the surface of the multimeter. In addition,
the vapours emitted by these substances are explosive and harmful to your
health. Do not use sharp-edged tools, screwdrivers or metal brushes to clean
the device.
Use a clean, damp, lint-free and antistatic cloth to clean the multimeter, display
and test leads. Allow the multimeter to dry out completely before using it again.
