Finding Cable Knots in Installation Tubes
Switch off the fuse and power down the electrical
circuit.
Power down any other cables in the tube and
connect them to the earth potential
Insert a cable probe (copper wire) or a draw wire up
to the bottleneck of the installation tube.
Connect the cable probe with a transmitter socket.
Connect the second measuring socket to the earth
potential.
Determine the error site my moving the receiver in
slow circles. Sensitivity can be adapted accordingly.
Finding Fuses and Electrical Circuits
Measuring under grid voltage! Observe safety provisions.
Connect the transmitter to a live grid outlet at the
phase (L1) and neutral (N) conductors.
Trace the search signal in the sub-distributor. Where
required, reduce sensitivity to find the right fuse.
Turn the receiver by 90° longitudinally to reliably
detect the different circuit breakers (solenoid coil
direction).
To achieve a better result, you should measure right
at the connections.
!Attention! The cover must only be removed by
electricians.
