Data can be logged over extended periods

Features include:

• Paper tape watch timing machine emulation with numeric and disk type readout.

• Average rate calculation using least-squares fit for improved consistency, especially with clocks

• Any beat rate from 1 tick per 30s (Atmos) to 400 cycles per second (tuning fork).

• Amplitude measurement of lever and co-axial escapement; lift angle 20° to 120°.

• High resolution beat error measurement.

• Clear and detailed waveform display for fault diagnosis.

• Trace magnification 1, 2, 5, 10, 15, 20, 30, 50.

• 'Paper' feed rate x 10, 5, 2, 1, 1/2, 1/5, 1/10, 1/15, 1/20, 1/30, 1/50, or 1/100.

• 'Tape' length of several metres can be 'pulled back' to examine earlier results.

• Positional results annotated onto tape, analysed and recorded to QC file.

• Long term graphical output with vernier readout and selective zoom.

• Graphs of rate, amplitude, deviation and beat error with variable smoothing.

• Fourier analysis of cyclical variations

• Allen deviation for assessment of stability

• Escape wheel eccentricity histogram
