Minimum voltage
This will determine the minimum voltage that can be applied to the
regulation valve. If too low, the valve won’t fine tune the dose rate. If
too high, the valve could have some unstable regulation.

Deadband
This will determine the regulation dead band. This setting will avoid
continuous regulation when the dose rate is very close to the target
doise rate. If too low, the valve could have some unstable regulation.
If too high, the real dose rate could be far away from the target.
