Replacing the Battery or Fuse
If the symbol
is displayed, the batteries are exhausted and
must be replaced by three new 1.5 V batteries (size AAA).
If it is not possible to measure currents in the ranges up to
200 mA and to test batteries or transistors, check the internal
fuse (F200 mA/250 V) and replace it, if required.
● Prior to opening the meter, always remove the test prods from
the measuring points of the circuit to prevent an electric shock.
● Never operate the meter when it is open.
1) To replace the batteries or the fuse, unscrew the grey battery
compartment cover on the rear side: Unfold the tilt stand so
that the two recessed head screws of the cover are accessible. Remove the screws and the cover of the battery compartment.
