GROUND BALANCE PROCEDURE - Nexus Standard MP V3 .
1. Turn the detector on from the Volume control.
2. Set the audio to a level comfortable for you.
3. Set the threshold to a barely audible level.
4. Set the discrimination level to 0 if a low frequency coil is fitted. For high frequency coils the discrimination level will be different. Read the User Manual on how to set the discrimination level.
5. Mineral Control and VCO Off.
6. Find ground free from metal.
7. Turn the Coarse ground balance knob to 10 (fully clockwise).
8. Begin moving the search coil up and down between 8 cm and 25 cm above ground.
9. If the detector beeps while the search coil is going up - turn the Fine GB knob slightly to the right.
10. If the detector beeps while the search coil is going down - turn the Fine GB knob slightly to the left.
11. Keep repeating step 8. & 9. until there are no beeping sounds when the search coil moves up and down. If the Fine ground balance is out of range (the detector beeps only when the coil goes down) then turn the Coarse GB to 9.5-9 to set a different GB range.
