Accuracy: 0.1% of measurement value +/- 0.03 s/24h (with annual calibration).
With GPS synchronisation (option): 0.1% of measurement value +/- 0.001 s/24h
Graphical display: Display range -1 s to +10 s, logarithmic scale.
Display of the instantaneous value independent of the measurement time
selected.
In the case of watches with inhibition compensation, simultaneous display of the
uncorrected quartz deviation.
Status displays: Countdown of the remaining measurement time.
Information No signal, Control, Run, Unstable, Out of range according to the
measurement status.
Pulse analysis (with analogue watches)
Result display: Pulse period of the stepping motor.
Inhibition period.
Pulse Width.
Drive Level
End Of Life (EOL) operating mode
Graphical display: Drive Level
Rate Measurement of Mechanical Watches (standard function)
Beat numbers: 18,000, 19,800, 21,600, 25,200, 28,800, 32,400 and 36,000.
Measurement time: 8 s.
Result display: Measurement range ±300 s/24h, resolution 0.1 s/24h.
Graphical display: Display range ±50 s/24h, logarithmic scale.
Module supply
Contact with the watch by means of movable probes or with measurement cables and probe tips.
Mirror for watching the hands during measurement.
Supply voltage: Adjustable, 0 - 3.5 V, resolution 0.05 V, accuracy ± 1% of measured value +/-
0.02 V.
Current limitation: 30 mA.
Current measurement
Instantaneous measurement of the IC current.
Integrating measurement of the total current during a measurement period.
Measurement time: Automatic determination based on a motor period, min. 2 s, max. 30 s.
Alternatively, manual entry according to the rate measurement.
Result display: Total current, IC current.
Measurement range 20 mA, resolution 1 nA.
Accuracy: +/- 2% of measurement value +/- 2 nA
Graphical display: Instantaneous current value during a measurement time of 2 s (independent of
the measurement time selected).
Display range 20 µA, logarithmic scale.
Fault displays: Acoustic signal and “out of measurement range” display when the current >20 mA.
