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 replacing the battery/fuse).
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.

c) Opening the battery/fuse compartment

The fuse/battery can only be replaced when all of the test leads are disconnected. The
battery/fuse compartment (P) cannot be opened when the leads are connected to the
terminals.
All terminals are automatically locked when the battery/fuse compartment is opened to
prevent leads from being inserted. The terminals are unlocked when the battery/fuse
compartment is closed.
The multimeter casing is designed so that you can only access the battery/fuse compart-
ment. The casing does not need to be opened and disassembled.
This makes the multimeter safer and easier to use.
Follow the steps below to open the battery/fuse compartment:
- Disconnect all test leads from the multimeter and switch the multimeter off.
- Loosen and remove the battery compartment screw (M) on the back of the multimeter.
- Collapse the fold-out stand and slide the battery/fuse compartment (P) off the bottom
of the multimeter.
- You should now be able to access the fuses and the battery.
- Repeat the above steps in the reverse order to replace the battery/fuse compartment,
and then screw it in place.
- The multimeter is now ready to use.
