11. Cleaning and maintenance

a) 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.

b) 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 meas-
ured 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.
