Sorting or determination of conductors already installed

(double-pole application)

Requirements:

• Any exisiting circuits within the cable must be voltage-

free.

• The lead terminals must be twisted and electrically con-

nected between each other

• You need several transmitters, with different transmitter

signals (A to F or 0 to 9).

• Connect the transmitter according to figure 19.

• Carry out this example as described in the application

example.

For this application example, please pay attention that the stripped lead terminals are twisted with

each orther.The electrical connection between the stripped lead terminals must be good.

In case only one transmitter is available, the sorting of the sheathed cables can be carried out by

sequentially reconnection the transmitter.

The switching with button 4 from »LEVEL I« to »LEVEL III« the sensitvity of Distance is increa-

sed up to a factor of 5.

Mains Voltage Detection Locating Line Interruptions

The test is performed in compliance with Figure 20.

No transmitter is required for this application.

• Set the receiver to the "Mains voltage detection" mode.

The bargraph display indicating the signal intensity (9e)

and the signal sound frequency depends on the level of

the voltage to be tested and the distance to the live con-

ductor. The higher the frequency, the higher the voltage,

or the lower the distance to the conductor.

Different signal intensities do not allow any assumptions regarding type and intensity of the vol-

tage present. A definite statement regarding the voltage present may only be made when using

a measurement instrument equipped with a display.

When testing mains connection cables for interruptions, make sure that both conductors are con-

nected once to the phase (turn mains plug by 180°).
