Move slowly forwards, backwards and to the sides, but avoid turning the probe. The probe should
always point vertical to the ground.
DO NOT
pivot, swing or rotate it.
5.3.2 Performing a Ground Balance
You may perform a Ground Balance if:
•
you get any target indications right at the start even though you do not move the probe or
•
your signal becomes unstable while scanning.
Press
to perform a Ground Balance. Please note that the Magnetometer can also react on
metallic trash or contamination laying on the surface or near to the surface. Make sure the probe
is not above such an interference during ground balancing. Moreover, hold the probe vertically to
the ground and do not move it.
Once the detector has re-balanced, you can continue with your scan.
The Ground Balance can be performed as often as you like.
