Fuse
Testing the Fuse
The fuse is tested automatically:
•
When the instrument is switched on with the rotary switch in
the A position
•
When the instrument is already on and the rotary switch is turned to
the A position
•
In the active current measuring range when voltage is applied
If the fuse is blown or if no fuse has been
inserted the “
FUSE
” symbol appears at the dis-
play. The fuse interrupts the current measuring
ranges. All other measuring ranges remain
functional.
Replacing the Fuse
If a fuse should blow, eliminate the cause of overload before plac-
ing the instrument back into service!
Attention!
!
Disconnect the instrument from the measuring circuit be-
fore opening the fuse cover in order to replace the fuse!
➭
Set the instrument face
down onto the working
surface.
➭
Turn the slotted screw
on the cover with the
fuse symbol counter-
clockwise.
➭
Lift off the cover and
pry the fuse out using
the flat side of the fuse
cover.
➭
Insert a new fuse. Make
sure that the fuse is
centered, i.e. between
the tabs at the sides.
➭
When replacing the fuse cover, insert the side with the guide
hooks first.
Tighten the screw by turning it clockwise.
➭
Dispose of the blown fuse with the trash.
Attention!
!
Use specified fuses only!
If fuses with other blowing characteristics, other current
ratings or other breaking capacities are used, the opera-
tor is placed in danger, and protective diodes, resistors
and other components may be damaged.
The use of repaired fuses or short-circuiting the fuse
holder is prohibited.
Note
Testing the Fuse with the Instrument Switched On
After inserting the fuse with the instrument switched on,
the instrument must be switched off briefly and then
switched back on again, or briefly switched to a non-cur-
rent measuring range and then back to the A measuring
range.
If contact is poor or the fuse is blown, the “
FUSE
” symbol
appears at the display.
9.4
Housing Maintenance
No special maintenance is required for the housing. Keep outside
surfaces clean. Use a slightly dampened cloth for cleaning. In par-
ticular for the protective rubber surfaces, we recommend a moist,
lint-free microfiber cloth. Avoid the use of cleansers, abrasives or
solvents.
9.5
Measurement Cables
Inspect the measurement cables for mechanical damage at regu-
lar intervals.
Attention!
!
Even in the case of minimal damage to the test leads, we
recommend sending them to GMC-I Service GmbH
without delay.
