3.3.2 Manual Fine Adaptation to Mineralized Soil
In case of difficult ground conditions the detector can be adapted manually to
the mineralized soil.
The achieved data will be stored deliberately until a new fine adaptation is
started (also if the detector is switched OFF, if batteries are missing, if keeping
on stock, a.s.o.).
Procedure:
1. Set the mode selector to position „mineral”.
2. Put the search head on the ground (please choose an area absolutely free
of metal)
3. Press button „C“ in the hand grip and keep it pressed.
4. Press button”+” in the hand grip and keep it pressed.
5. After 3 seconds while keeping button „C“ and button “+” pressed a short
tone (beep) becomes audible.
6. While hearing the short tone (beep) stop pressing button “+” but continue
to keep button „C“ pressed.
The metal concentration of the previous soil is now indicated by one of the
14 diodes of the LED display.
Lift up the search head and move it back to the ground. While keeping
button “C” pressed you can adjust the setting for the mineral concentration
by pressing the buttons “+” respectively “-“ until it corresponds to the soil
conditions and no more audio signal is produced during these up-and-
down-movements.
