3.1.8 Detect the power supply circuit on the same floor
When detecting the power supply circuit on the same floor, please take the following
steps:
1).Turn off the main switch in the distribution box of this floor;
2).Disconnect the neutral wire in the distribution box of this floor from the neutral
wires of other floors;
3).Connect the transmitter in a way shown in Fig.3-1-8.
For the sake of safety, please
cut off the power of the whole
building to make it uncharged.
1.The grounding end of the transmitter should be properly grounded, and should be
a certain distance away from the pipeline to be detected. If the distance is too
short, the signals and the circuit cannot be precisely located.
2.Adjust the transmitting power of the transmitter to adapt to different radiuses of
detection.
3.In the process of detecting and tracking the pipeline, the stronger the signals
displayed on the Nixie tube of the detector, the closer the pipeline detected by the
detector.
4.Select the manual mode on the receiver and select suitable receiving sensitivity to
precisely locate the pipeline.
3.2 Dual-pole Applications
3.2.1 Search for the fuses
In a building with multiple residences , use the L and N ports on the socket of any
residence to feed the signals from the transmitter (as shown in Fig.3-2-1), and adjust the
transmitting power of the transmitter to a suitable level.
Preconditions:
※
Turn off all the air switches in the distribution box;
※
Connect the transmitter according to Fig.3-2-1.
When connecting charged circuits
to the transmitter, please do abide
by the safety instructions.
1. The identification and positioning of fuses are greatly influenced by the wiring
situation in the distribution panel. In order to search for fuses as precisely as
possible, one should open or dismantle the cover of the distribution panel, and
search for the feeder of fuse.
2. ln the searching process, the fuse with the strongest and the most stable signals
is the target to be searched for. Due to the coupling of signals, the detector may
detect signals from other fuses, but the strengths of those signals are relatively
weak.
1. When detecting, it is better to put the probe of detector into the inlet of the fuse
box to achieve the best result of detection.
2. Adjust the transmitting power of the transmitter to adapt to different radiuses of
detection. Select the manual mode on the receiver and select suitable receiving
sensitivity to precisely locate the circuit.
