9.2.3 Ground Balance
A correct soil reconcilation (Ground Balance) is absolutely necessary that the adjusted discrimination
can work properly. If the soil reconciliation is not done correctly the operation of the device and the
integrated discriminator cannot work properly.
In the following section you can find a list of all necessary working procedures to do a correct soil
reconciliation:
1. Power on the eXp 4000 and connect the DDV system.
2. Adjust the discriminator on the material you like, see previous section.
3. Put the device with coil approx. 10 cm above the ground.
4. Select the operating mode "Metal Detector" and confirm it.
If you hear an acoustic signal from the DDV system after these indications, then the ground balance is
not finished correctly. Repeat these steps until there is no acoustic signal from the metal detector.
The following causes can prevent a correct soil reconciliation:
•
You are staying above a metalic object.
•
You confirm the operating mode "Metal Detector" without holding the coil directly above the
ground.
•
During the confirmation of the operating mode "Metal Detector" you are holding the coil to high
and then minimize the distance to the ground.
•
You are turning the discriminator during ground balance.
Only if you are doing a correct soil reconciliation the functionality of discrimination can be
guaranteed!
