3.4 Replacing the Fuse
The instrument is protected by a fuse. You can find it on the rear panel between
the main power switch and AC power supply.
Type of fuse: Size 5x20 mm, 250V~, T2.5H (slow-blow), IEC60127-2/5
Risk of electric shock
The fuse is part of the main power supply. Therefore, handling the fuse
while power is on can lead to electric shock. Before opening the fuse
holder, make sure that the instrument is switched off and disconnected from
all power supplies.
Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of
the same type and rating.
1. Pull the fuse holder out of its slot on the rear panel.
2. Exchange the fuse.
3. Insert the fuse holder carefully back in its slot until it latches.
