5. Approach to the supposed place of cable route, on which the signal from the generator was
transmitted. Locate the receiver axis in parallel to the communication axis.
The graphic of change of the signal level will be displayed on the screen in frequency 512 Hz,
on the 2D image of the route of the cable located near (if any) will be displayed under the voltage
50(60)Hz.
You should move the receiver as shown on the figure.
The place of crossing of cable corresponds to the setting of the pointer «50 Hz» onto the center of
the circle at maximum value of the indication on the «Graphic» of the active frequency signal.
communication axis «50 Hz»
is in the center
communication axis «512
