Testing of ground plots
In order to avoid damage, the ground plots shall be tested to locate and trace the current-
conducting utilities before excavating.
4.7.1
Passive locating without Transmitter
The territory may be located in response to re-radiated power, telephone, broadcasting signals or
signals of electrochemical protection. Make tracing on the frequencies:
50 Hz,
100 Hz,
Eter (SB),
Radio.
Set the Receiver gain so that
a half of the “peak” bar graph is illuminated. Move in zigzags, by al-
ternating your direction in perpendicular every 1 to 5 m (
). The signal strength will peak where
the utility is. Survey as explained in Section 4.6.2.1 to confirm that you have pinpointed the utility. Find
the direction of the located utility rotating the Receiver on vertical axis. The
peak signal
is generated
when the Receiver plane is
perpendicular
to the utility line, the
minimum
one
– when it is
parallel
.
Fig. 31 Testing of ground plots without the LKN Transmitter
If you are locating a single utility line in the area and with a strong signal, it is recommended to enable
Compass line
to facilitate tracking (Section 4.6.2.4).
