5.2.2.3 Classify or define the laid current circuit
Preparation:
-
The circuit must be unloaded.
-
The ends of the core wires must be twisted with each other and conduct all together.
-
Connect the transmitter as in the following figure.
- If there is current in the cable, first turn off the power to make the cable unpowered.
- The ends of the non-shielded core wires must conduct together and need to be twisted with each other.
- If only one transmitter is used, carry out multiple measurements while changing the connection between
the transmitter and the core wire of the cable.
- When changing the connection between the transmitter and the core wire of the cable various current
circuits can be distinguished when the coding of the transmitter is changed in the process of transmission.
- Set the power of the transmitter in order to adjust it to different search radii.
- Buy a transmitter with different transmission signals, if necessary.
