Replacement Of Fuses - Hameg HM6050-2 Handbuch

If there is any suggestion that safe operation is not possible, the
instrument must be disconnected and secured against unintentional
operation. This may occur:
• if the instrument has visible damage,
• if the instrument has loose parts,
• if the instrument does not function,
• after long storage under unfavorable circumstances (outdoors or in
moist environments),
• after excessive transportation stress (e.g. in poor packaging).

Replacement of fuses

The internal power supply unit of the HM6050-2 contains a fuse.
At delivery the HM6050-2 is set to 230V ±10% (50-60Hz). If the
instrument shall operate at a mains voltage of 115 V ±10%, the wire
bridges have to be changed by soldering.
Insert or replace fuses according to the selected AC voltage!

For fuse replacement the instrument has to be opened by unscrewing
the two cap nuts at the back panel. Then remove the two handle and the
handle covers itself. The cover now can be moved to the backside of the
instrument. The fuse is located at the rear side of the encapsulated
power transformer on the main PCB.
