a) General information
Regularly check the device and test leads for signs of damage.
• The multimeter should be calibrated once a year to ensure that it remains accurate.
• The multimeter is maintenance-free (apart from occasional cleaning and replacing the batteries).
b) Cleaning
Always observe the following safety instructions before cleaning the device:
Opening any covers on the product or removing parts – unless this is possible by hand – may
expose voltage-carrying components.
Before cleaning or repairing the device, disconnect all cables from the multimeter and the measured
object, 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 device/display and the test leads. Allow the product to
dry completely before using it again.
