Cleaning and Maintenance

General Information

To ensure the accuracy of the meter over an extended period of time, it should be calibrated once a year.
Apart from occasional cleaning and fuse replacements, the meter requires no servicing.
Information on changing the battery and fuse is provided below.
Regularly check the technical safety of the instrument and measuring leads, e.g.
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 leads 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 cleaning agents which contain carbon, petrol, alcohol or similar substances for cleaning pur-
poses. These could corrode the surface of the measuring instrument. The vapours are also detrimental
to health and are explosive. Sharp-edged tools such as screwdrivers or metal brushes should not be
used for cleaning purposes.
When cleaning the device or the display and the measuring leads, use a clean, lint-free, antistatic, slight-
ly damp cloth. Allow the product to dry completely before you use it again to conduct measurements.

Inserting and Changing the Batteries

Operation of the meter requires six mignon batteries (AA). You need to insert new, charged batteries pri-
or to initial operation or when the battery change symbol
38
appears on the display.
