6. There are massive metal objects near the receiver antenna.
7. There is a source of electromagnetic interference (for instance, the vehicle with running
motor) near the measurement point.
8. The signal incoming to the receiver sensors is too strong and thereby distorted.
Some of such situations are recognized by the receiver. For example, figure 2.13: when there is a
minimum signal instead of switching to the mode of minimum the error message «Err 4» appears
on the screen. Here “4” is an error code.
Code Meaning
Err 1 Signal is too weak
Err 2 Signal is too high
Err 3 Field is heavily distorted
Err 4 Not on the route axis
Unfortunately, the receiver cannot always detect the distorting factors. If there are doubts
regarding the correctness of depth defining, the following techniques can be used to detect some
of the distorting factors:
- Conduct 5-10 measurements of depth in a row without moving the receiver. The readings must
not differ at more than 20%.
- The position of route axis obtained by the method of minimum and the method of maximum
must not differ at more than 20 cm.
- Lift the receiver at 20 cm above the ground and repeat the measurement
– the reading must
have a 20 cm increase as well.
The depth can be also defined by one of the indirect techniques (the receiver shall be in the mode
of maximum, «SuperMax» shall be off).
If the conditions allow depth measurement but do not allow defining the current, the latter is
not output.
2.10 Work procedure for passive route detection
This mode of search is intended to locate and trace the
underground engineering buried utilities and does not require
use of the generator. The modes “50/60 Hz”, “100/120 Hz” a re
to be used.
Turn on the receiver by depressing the receiver power button
pos.5. figure 2.14. The receiver conducts the short test of the
indicator and displays the current supply voltage in volts and
current operation frequency in kHz (F=8.92).
