14.4 Changing the fuse
The two current measuring inputs are equipped with high-performance ceramic fus-
es. If you cannot take measurements in this range, you will need to replace the fuse.
Proceed as follows to replace the fuse:
Disconnect the test leads from the measurement circuit and the multimeter.
Power the multimeter off.
Remove the battery and fuse compartment cover (see “Opening the battery and
fuse compartment” for details).
Replace the defective fuse with a new one of the same type and nominal volt-
age. The fuses have the following specifications:
Ceramic Superflink 10 A/1000 V, 10 kA disconnecting capacity
Dimensions: 37 mm x 10 mm
Ceramic Superflink 600 mA/1000 V, 6FA
Dimensions: 32 mm x 6.4 mm
Carefully replace the battery and fuse compartment cover.
Using patched fuses or bridging the fuse holder is not permitted for
safety reasons. This may cause a fire or explosion. Never use the
multimeter when the battery and fuse compartment is open.
14.5 Inserting/changing the battery
The multimeter is powered by three micro batteries (AAA). Insert three new, fully-
charged batteries before using the multimeter for the first time or when the low
battery symbol
appears on the display.
Proceed as follows to insert or change the battery:
Disconnect all circuits from the multimeter and test leads. Disconnect all test
leads from the multimeter. Power the multimeter off.Remove the battery and
fuse compartment cover (see “Opening the battery and fuse compartment”).
Replace the used batteries with new ones of the same type. Insert the new bat-
teries into the battery compartment with the correct polarity. Pay attention to the
polarity markings in the battery compartment.
