d) Setting the Signal Code
The default setting for the signal code is 1. If you want to use several transmitters in one cable test, the transmitter
code can be changed to a value between 1 and 7.
• To set the signal code, proceed as follows:
Switch off the transmitter.
Hold down the "LEVEL" (15) button and turn on the transmitter. Then release the power button (16).
The pre-determined signal code will appear on the display. Now release the "LEVEL" button.
Press the "LEVEL" button again to switch to the next code.
When you have set the desired code, briefly press the power button (16). The transmitter will return to the normal
operating mode. The selected code is now active and will appear on the display.
e) Performing Test Measurements
Before using the cable detector for the first time, familiarise yourself with its function. This works best with
a simulated error source.
Take a piece of 3-pole installation cable (approx. 5 meters) and attach it temporarily to a wall that is accessible
from the front and back. Remove the jacket isolation approx. 1.5 m away from the cable end. Cut one of the cable's
conductors. Connect the transmitter to the test cable as indicated. Connect the interrupted conductor to the red
measuring socket, and then connect the other conductors to the black socket. Also connect the black socket to
the earth potential.
Switch on the transmitter and receiver.
Move the receiver along the cable until the interruption is detected. Repeat this on both sides of the wall.
For optimal test results, vary the signal strength at the transmitter or the sensitivity at the receiver (manual mode).
