Weishi No 1000 Timegrapher for measuring the rate, amplitude and beat error of a mechanical watch.
Weishi No 1000 Timegrapher for measuring the rate, amplitude and beat error of a mechanical watch.
Frequency can be detected automatically or entered manually.
Rate deviation measurement is ± 999 sec/day, with a precision of 1.0 sec/day.
Amplitude measurement is a numerical display in degrees, resolution is 1°, measuring range: 100°to 360° (the lift angle can affect the amplitude, range: 30°to 70°. Under normal circumstances, the amplitude value should not exceed 360°.)
Measuring period times for the averaged numerical results: 2s, 4s, 8s, 10s, 20s, 30s, 30s, 60s.
Measuring of the Beat error (Frequency error) is a numerical display in milliseconds. Resolution is 0.1 milliseconds; the measuring range is 0-9.9 ms.
Lift angle range is 30° to 70°, the factory default setting is 52°. The default setting is sufficient when the lift angle is unknown.
