check for damage to the housing or squashing etc.

Cleaning

Always observe the following safety instructions before cleaning the device:



Live components may be exposed if covers are opened or parts are removed (unless

this can be done without tools).

The connected lines must be disconnected from the measuring device and all mea-

suring objects prior to cleaning or repairing the device. Switch the DMM off.

Do not use any carbon-containing cleaning agents or petrol, alcohol or the like to clean the product. These

could corrode the surface of the meter. Furthermore, the fumes are hazardous to your health and explosive.

Moreover, you should not use sharp-edged tools, screwdrivers or metal brushes or similar for cleaning.

When cleaning the device or the display and the measuring lines, use a clean, lint-free, antistatic, slight-

ly damp cloth. Allow the product to dry completely before you use it again to conduct measurements.
