6.2.3 Replacing the fuses
The fuse is located on the rear of the instrument, directly underneath the
on/off switch.
Required accessories ￭ Spare fuse, type: 250 V, 5 A, slow-acting fuse, 20 mm
1 Switching off the instrument
￭ Turn the on/off switch (2-1) to the position O.
NOTE
We recommend pulling out the power supply cable in addition.
The instrument can thus not be accidentally switched on while you
insert the fuse.
2 Removing the old fuse
￭ Unscrew the fuse holder by hand (if necessary, unscrew it using a
size 5 flat-head screwdriver).
￭ Pull the old fuse out of the holder.
