Move the receiver or a non-contact probe connected to the receiver along the safety devices. The
location of detected circuit will be indicated on the receiver.
3.4.7 Clamp mode - CL
Clamp mode "CL" is used for introducing signal into circuit, where it is impossible to disconnect
the line.
Fig. 13 Diagram of the clamp mode.
Transmission clamps are used in closed circuits, which may carry AC up to 15A.
Remember that the current value in the tested system of 50/60Hz must not cause the saturation
of clamps (in such case characteristic buzz is heard in the clamps).
If possible, fix the clamps on a multi-core cable, not on the individual cores (conductors).
3.4.8 Mode for detecting 50Hz/60Hz electric field - NEON
Using only the receiver you may use non-contact "Neon" mode to locate wires under voltage with
a frequency of 50Hz/60Hz. Remember that the electric field is deformed by various conductors e.g.
reinforcement bars, steel or copper pipes etc. If a conductor with 230V AC of 50Hz runs near a con-
ductive tube, a voltage with frequency of 50Hz may be induced in the pipe causing false results.
Fig. 14 Diagram of detecting 50Hz/60Hz electric field.
