turn ground balance pots – how do they work?
There are two versions of multi-turn ground balance pots in Tesoro Metal Detectors: a 10 turn and a 3.5 turn. All current models use the 3.5 turn pot. When turning either one, it’s best to get a reference point to start. To do this, turn the 10 turn pot 11 times CCW, and the 3.5 pot turn 4 turns CCW. This will assure the pot is at the beginning of it’s working range. In both pots, you may not feel the end of the range because when it gets there, the pot will still turn freely. This is NORMAL and will in no way damage anything. If you have a good sense of touch, you will probably feel a slight drag when it gets to either end of it’s working range. Follow the procedures in your owners manual from then on. Other multi-turn pots may work differently, but the ones used on Tesoro Metal Detectors work as outlined above.
