5.6.3 Perform Measurement
1
Hold the probe vertically.
Move the detector back and forth ...
... but keep the orientation of the probe
parallel to your starting orientation.
2
Move the detector to the sides ...
... but do not pivot, swing or rotate the probe.
3
4
If the signal becomes unstable, point
the probe to a neutral (non-ferrous and
non-magnetic) surface ...
... and press the trigger or tap on
to
perform a Ground Balance. The bar graph is
immediately reset to the zero line.
In Ferro Pointer View, tap on
or press
the trigger to reset the indicator.
5.6.4 Interpret Measurement
Magnetometer provides
•
acoustic feedback (if Sound is enabled),
•
vibration feedback (if Vibration is enabled) and
•
a basic visual representation.
As soon as you get a clear signal, the device has detected a potential metal target in front of
(horizontal measurement) or below (vertical measurement) the probe respectively.
As soon as the probe is very close to the detected object, the values reach its peak and indicate
a hit with vibration.
The bar graph shows BLUE
peaks if the probe is pointing
at the negative magnetic
pole of a ferrous object.
The bar graph is in the
GREEN range (close to zero
line) if there is no ferrous or
magnetic target object.
The bar graph shows
RED
peaks if the probe is pointing
at the positive magnetic pole
of a ferrous object.
The indicator is in the BLUE
zone if the probe is pointing
at the negative magnetic
pole of a ferrous object.
The indicator is in the GREEN
zone if there is no ferrous or
magnetic target object.
The indicator is in the
RED
zone if the probe is pointing
at the positive magnetic pole
of a ferrous object.
5.6 MAGNETOMETER
Use the operating mode Magnetometer to detect small metal objects like nails, screws and
wires made of ferromagnetic materials such as iron, nickel and cobalt close to the surface. Re-
move these items from the scan field before performing further scans!
The fewer small metal items in the soil, the deeper you can detect targets with 3D Ground Scan.
Moreover, use Magnetometer to pinpoint objects during excavation.
Make sure you have plugged in the Ground Scan Probe (G).
This operating mode allows vertical and horizontal (short-range)
probe orientation.
