If the transmitters are connected in accordance with the figure 13, the receiver

indicates "C" at the left side of the line interruption. If you continue further than the interruption, to-

wards the right, the receiver displays "F". If you are directly above the interruption, no line code is

displayed, due to the overlapping of both transmitter signals.The line interruption is located exactly

in the middle between the displayed line codes "C" and "F

Conditions:

• The current circuit must not be live.

• All lines not being used must be connected to the auxiliary ground as shown in the figure.

• Connect both transmitters as shown in the figure..

• Proceed as described in the application example.

The ground connected to the transmitter and to

the wires not being used can be as follows is: an

auxiliary ground, an orderly connected ground

contact of a home office socket, or an orderly a

grounded water pipe.

Please make sure during line interruption loca-

ting in multi-wire shielded conductors and ca-

bles, that all remaining wires are orderly groun-

ded. This is required to avoid inductive

disturbance (by capacity coupling).

The locating depth for shielded conductors and cables varies, as the individual wires within the

shield are twisted.

The transition resistance of a line interruption must be higher than 100 kOHM.The verification of re-

sistance can be carried out by any multimeter.

• Systematically circle the interruption by changing the sensitivity.

The switching with button 4 from »LEVEL I« to »LEVEL III« the sensitvity of Distance is increa-

sed up to factor 5.

Setup: manual mode, minimal sensitivity.Tracing depth max. 2 meters.
