7.2.2 Replacing the fuses
Fuse values are shown on the metal caps of the
replacement fuses - the fuse imprint looking
more or less as shown on the left (may vary
slightly depending on fuse type).
Amperage (A) is the parameter that is important
for allocating fuses correctly to the correspond-
ing fuse holders (shown in the example on the
left: line fuse 2xT10A ).
Two fuse holders are located on the rear panel of
the instrument - see Fig. 76
on the left. The top
imprint ‘line fuse’ refers to the line fuses (2xT10A)
in the voltage selector (Fig. 77).
Check the instrument malfunction table (chap. 6.2
‘Instrument / accessories not working’) to find out
which fuse needs to be replaced.
Example:
Instrument not working --> possibly the line fus-
es 2xT10A (Fig. 77) need to be exchanged; i.e.
select the correct replacement fuses (10A) as per
the instructions on this page.
Replacing the fuses: --> proceed to next page.
Prior to exchanging any fuse, always switch the instrument off and unplug the mains plug.
Defective fuses may be replaced only with the replacement fuses supplied together with the
instrument or with other replacement fuses of exactly the same type / specification!
Important!
Follow the instructions below to make sure you select the correct replacement fuse for each
fuse holder.
Selecting the correct replacement fuse
The amp value (here 10A) printed on the fuse and the
amp value next to the fuse holder on the rear panel of
the instrument MUST be identical!
