- Close the casing again carefully.
Using mended fuses or bridging the fuse holder is not permitted for safety reasons. It may cause
fires or arc explosions. Never operate the meter when it is open.
e) Inserting and changing the battery
Operation of the meter requires a 9 V block battery (e.g. 1604A). You need to insert a new, charged battery before
initial operation or when the battery change symbol appears on the display.
The battery status is displayed via a dynamic icon. It changes appearance depending on battery status. When the
empty symbol flashes, a new battery must be inserted to avoid measuring errors.
The following symbols can be displayed:
Battery full
Battery nearly empty Battery empty
Battery empty, meter switches off
Proceed as follows to insert or change the batteries:
- Disconnect the meter and the connected measuring lines from all measuring circuits. Remove all measuring lines
from your meter. Switch off the DMM.
- Open the casing as described in chapter “Opening Meter”.
- Replace the flat battery with a new one of the same type. Place a new battery in the battery compartment, observing
the correct polarity.
- Close the casing again carefully.
