Cable locator
exists) of the power supply may find the emitter current circuit, causing the
current switch to trip. E.g. FI / RCD trips
Recommendations
1.
When using the emitter as a voltage tester to check the mains voltage, a
small spark will be produced when the probe touches the mains voltage,
this is normal.
2.
If any of the on / off, code, and level keys are active, the other two are
disabled.
3.
If the receiver is in automatic mode, it can switch to manual mode or
mains voltage identification mode at any time; If the receiver is in manual
mode, both the UAC key and the Manual key will be enabled when
exiting manual mode.
2.2 Principle of operation
The cable locator includes an emitter, a receiver and accessories. The
emitter sends to the target cable (or metallic pipes) an AC voltage modulated
by digital signals, which generates an alternating electric field (see Fig. 2-1);
place the tip of the receiver close to this field, and the sensor will generate
induced voltage. This instrument can amplify this weak signal hundreds of
times and display it on the LCD screen after digital processing, in this way the
position of buried cables or pipes, as well as their faults, can be detected
based on the change of the signal.
Caution!
1.
For any application, the emitter connections must ensure a closed circuit.
2.
This cable locator can only detect or locate correctly connected lines
according to the described physical principle.
