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 mul-
timeter and all measured objects. Power the multimeter off.
Do not use aggressive detergents, benzine, alcohols or similar products for cleaning. These
may corrode the surface of the measuring device. In addition, the vapours emitted by these
