Hoefer UV20 - Manual (Page 15)

Replacing fuses
Fuses protect equipment by disconnecting loads
too large for the instrument’s circuit design. For
continued protection, only replace fuses with the
specified voltage and current ratings.
Each of two round modules on the left side of
the control panel (above the mains power cord
receptacle) holds one T 1A/250V 5 × 20 mm
(Slow blo) fuse.
1
Caution! Set the power switch to OFF and detach the
power cord before replacing fuses.
2
Insert a small flat-blade screwdriver into the slot on
the fuse module and turn it ¼ turn counterclockwise.
The spring-loaded module cap will loosen. Pull the
cap/fuse holder out.
3
Pull the fuse out of its holder and inspect. If the fuse
element is burned or broken, replace the fuse with an
identical type. If the fuse appears to be intact, check
it with an ohmmeter.
4
Insert a good fuse into the holder and then insert
this assembly back into the unit. Seat the module by
inserting the screwdriver into the slot, pressing gently,
and turning the cap ¼ turn clockwise.
