3. DETAILS OF APPLICATION
3.1 In open circuit
※
※
Finding and tracing lines, sockets, junction boxes, switches, etc. for house
installations;
※
Finding bottlenecks, kinking and buckling and obstructions in installation pipes by
means of a metal wire.
Detecting line interruptions in wall or floor;
When using this application, please ensure the good functioning of the protective
ground wire.
1. Application in open circuit is suitable for finding sockets and switches in dead
equipment
2. The tracing depth is depending on the medium and application. A typical tracing
depth is 0 ~1m.
3. The protective terminal of an electrical outlet can be used as the grounding
connection of the transmitter.

3.1.1 Locating of line interruptions
Preconditions:
※
The circuit must be dead.
※
All lines which are not required must be connected to the auxiliary ground in
accordance with Fig. 3-1-1.
※
Connect the transmitter to one lead and to an auxiliary ground according to Fig.3-1-1.
Fig 3-1-1
1.Full grounding should be ensured.
2.The transition resistance of a line interruption must be higher than 100k Ohm.
3.When tracing line interruptions in multi-core cables, note that all remaining
leads in the shielded cable or conductor must be grounded in accordance with
the regulations. This is required to avoid cross-coupling of the fed signals ( by a
capacitive effect to the source terminals). The tracing depth for shielded cables
and conductors are different, as the individual leads in the shielded cables are
twisted around themselves.
1. The ground connected to the transmitter can be an auxiliary ground, earth from
an earthed socket or a water pipe which is properly earthed.
2. During tracing along the line, the position at which the signal received by the
receiver has an abrupt decline is the position of the interruption.
3. Adjust the transmitting power level of the transmitter to adapt it to different
detection radiuses.
4. The target position can be precisely located by your setting of the manual mode
of the receiver and selecting of the proper sensitivity.
