9.2 Replacing the mains fuse
If the display remains dark after you switch on the instrument, this
generally means that the instrument's fuse is faulty and has to be
changed.
DANGER
Unplug the instrument from the mains before replacing the fuses.
• Screw open the fuse holder on
the back of the instrument
using a screwdriver, screwing
anticlockwise.
• Replace the faulty fuse:
– 230 volt variant:
T 3.15 A, 230 V, 5x20 mm
– 115 volt variant:
T 6.3 A, 115 V, 5x20 mm
• If the instrument still does not
work after replacing the fuse,
contact the Precisa Service
Center.
DANGER
Under no circumstances should you use other fuses or attempt to
bridge the fuse.
