mA Range
If the FF1A/380V AC fuse link for the active mA current measuring range is
tripped, FUSE appears at the digital display and an acoustic signal is generated
simultaneously.
Replacing Fuses for mA Ranges
➭
Open the instrument as described for battery replacement.
➭
Remove the blown fuse, which is situated under the batteries, e.g. with the
help of a test probe or a similar object, and replace it with a new fuse.
Attention!
!
Only fuses with the specified characteristics may be used (see chapter
14, “Characteristic Values”)! The use of fuses with other tripping char-
acteristics, current ratings or breaking capacities represents a hazard
for damping diodes, resistors and other device components. The use
of repaired fuses and short-circuiting of the fuse holder are prohibited.
15 A Range
A humming sound originating from the 15 A circuit breaker is normal when
measuring high value alternating current.
If the miniature 15 A circuit breaker for the active current measuring range is
tripped, FUSE appears at the digital display and an acoustic signal is generated
simultaneously. Make sure that the red pin is popped out in the tripped condition,
i.e. that no adhesion or fusion has taken place. Short circuit the
Ω
and 15 A jacks
with the selector switch set to the continuity test position, and “
0L
” must appear
at the display.
Attention!
!
Inspect the measuring circuit and eliminate the cause of overload
before activating the reset button at the miniature circuit breaker.
15.3 Housing
No special maintenance is required for the housing. Keep outside surfaces clean.
Use a slightly dampened cloth for cleaning. Avoid the use of cleansers, abrasives
or solvents.
