Operation

Cleaning

Use a damp cloth and mild household cleaning agent to clean the instrument
should it become soiled through daily use. Never use aggressive cleaning
agents or solvents to clean the instrument.

Changing the battery

Change the battery when the battery symbol is displayed. Remove the test
leads from the measuring instrument before changing the battery or fuse!
Remove the two screws on the rear of the instrument, open the battery com-
partment and remove the used batteries. Insert new battery (1 x 9 V Block
6F22). Replace battery compartment cover and screw tight.
Only use the specified batteries!
Do not dispose of batteries in normal household rubbish! Observe
statutory regulations pertaining to disposal!

Changing the fuse

When changing the fuse, remove the measurement leads from the device
and remove the screws on the rear of the device (two at the bottom, one at
the top). Carefully remove the rear of the housing and replace the fuse with
fuse of the same type (Fuse F 10 A / 1000 V). Replace screws and screw
tight.
The F200 mA fuse is self-resetting and therefore maintenance free.
Only use the specified fuse!
