The housing design only allows access to the battery and fuses when the com-
partment is open. The housing no longer needs to be fully opened and taken
apart.

This increases user safety and the user-friendliness of the device.

Proceed as follows to open the compartment:
- Disconnect all measuring lines from the meter and switch it off.
- Unscrew and remove the battery compartment screw on the back of the

device (14).

- With the attachment clip folded away, pull the battery and fuse compartment

cover (17) downwards and off the meter.

- The fuses and the battery compartment are now accessible.
- Proceed in the reverse order to close the housing and screw the battery and

fuse compartment securely into place. 

- The meter is ready for use once again.

The current measuring ranges are secured with high performance fuses. If measuring in this range is
no longer possible, you have to change the fuse.
Proceed as follows for replacement:

- Separate the connected measuring leads from the measuring circuit and the measuring device.

Switch the DMM off.

- Open the housing as described in the chapter “Opening the Measuring Instrument”.

- Replace the defective fuse with a new fuse of the same type and nominal voltage. The fuses have

the following values: 

F1

F2

F10A 600V (6.35 x 31.8 mm)

FF 200 mA 600V (32 x 6 mm)

F10A 600V (6.35 x 31.8 mm)

3 x F 160 mA/600 V self-resetting, 
PTC (32 x 6.2 mm)

F10A 600V (6.35 x 31.8 mm)

FF 400 mA 600V (6.35 x 31.8 mm)
