Assigning Fuses

When connecting in live circuits, the safety prescriptions must absolutely be
respected.
The detection or assignment of the fuse strongly depends on the wiring rea-
lised within the distribution. To obtain a result as precise as possible, the
cover should be removed and the supply line to the fuse should be traced.
Safety cut-outs of different manufacturers have different installation positi-
ons for magnetic coils. If no evident signal can be found by the receiver in
the position shown below it is advised to modify the position by 90° towards
the left or the right.
• Switch on the instrument via the on/off switch/ensitivity potentiometer (5).
• Set selection switch between Fuse and Cable to "Fuse" (4).
• Plug the transmitter into a current circuit socket to which the fuse is to be
assigned.
• Set sensitivity level to maximum sensitivity via the potentiometer (5).
• Now approach the fuses with transmitter sensor (1) and try to receive a si-
gnal. A signal received is indicated by the symbol "H" on the display as well
as the blinking of the LED (2). At the same time an acoustic signal is audible
depending on the intensity of the signal.
• If a reception signal is received at several fuses, reduce the sensitivity level
via the potentiometer (5) until the minimum reception of the signal is achie-
ved. Repeat this procedure until only one fuse indicates a reception signal.
This fuse protects the socket to which the transmitter has been connected.
Please make sure that in rare cases a fuse assignment may be considerably
impeded due to the internal wiring of the current distributors (see drawing
below).
The tracing depth amounts to approx. 0...10 cm.
