Rate deviation, amplitude and beat error of mechanical watches
and diagram recording of the beat noises.
Measuring
possibilities
Automatic determination of all common beat numbers. Manual
selection for less common beat numbers. Manual selection for
any beat number in the range between 3'600/hour to 36'000
b/h. Automatic determination of an unknown beat number.
Beat number
Automatic gain control. Manual control possibility for watches
with side noises or unusual beat noises.
Gain control
