4. Once the ground balance is done, the ground balance value will appear on the LCD panel
as well as the numeric display on the handle. If you continue to press and hold the ground
balance button, the device will keep on ground balancing and beeping. To make sure that
the ground balance adjustment is correct, please repeat the process 2 or 3 times and each
time check the value on the display. The difference between the values should not be
greater than 1 or 2 numbers.
5. If you cannot ground balance, meaning you don't hear the beep, either the ground is very
conductive or not mineralized or there must be a buried metal object underneath the coil.
In such a case, move to another location and re-ground balance. If you still cannot succeed,
try manual ground balancing.
After the ground balance button is released, the device will work in the General Search
mode and the ground balance value will remain on screen for a while. (If you do not want to
wait for this period, you can go to the main screen by pressing and releasing the pinpoint
button once). This gives you the opportunity of fine tuning the automatic ground balance
value. Please refer to the following MANUAL GROUND BALANCE section for more details.
MANUAL GROUND BALANCE:
It is the process where you set the ground balance value manually. Because it is more time
consuming, it is not preferred by most users. However, it becomes useful when ground
balance cannot be achieved by other methods or when you need to fine tune the automatic
ground balance value.
FORS Relic
is designed in a way that you can easily auto ground balance it on all types of
ground. Therefore, we recommend that you use automatic ground balance at start up.
However, some soils are not suitable for automatic ground balancing (except for the COG
mode). For example; wet beach sand, soils containing alkali or salty water, trashy areas,
plowed lands, highly mineralized ground or ground with very low mineralization are not
suitable for automatic ground balancing. We recommend you to manually ground balance
in such areas for your convenience. Manual ground balance requires experience acquired
with some practice.
To ground balance manually:
1. Find a spot on the ground where there is no metal and switch the device to the GEN mode.
2. You need to listen the sounds coming from the ground in order to perform manual
ground balance. Pump the search coil up and down from about 15-20 cm (~6''- 8'') above the
ground down to 3 cm (~1'') off the ground.
If the sound gets louder as you lift the search coil off the ground, it means that the ground
balance value is too low. In other words, the ground is negative and you need to increase the
ground balance setting with the up button.
