HG G-19370ZA

7.4.3 (3) Calibration Config

–

Poti1 / Poti2: Configuration of the gain for the induced voltages. 0 means minimum 
gain, 255 is maximum gain. Th einduced voltages depend on the current in the guide 
wire and the distance to the guide wire.

ATTENTION!

In order to avoid overmodulation the gain should not be too high! This means that the sum

 

of all simultaneously occurring sum and difference voltages has to be less than 3,3V.

–

Threshold: This value (in mV) regulates the sum voltage threshold. If the sum voltage 
exceeds this threshold the track detect signal is generated.
