11. Cleaning and maintenance

a) General
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).
Refer to the following sections for instructions on how to change the battery.
Regularly check the device and test leads for signs of damage.
b) Cleaning
Always observe the following safety information 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 all
measured objects. Switch off the multimeter.
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
