For sale Witschi Chronoscope S1 watch timing machine and ac adaptorTECHNICAL DATA  (description from user manual - supplied in digital version that can be printed out if necessary) Measuring possibilities: rate deviation, beat error and amplitude of mechanical watches. Diagram of the beat noises.   Beat number: automatic selection of all common beat numbers. Manual selection of any beat number in the range between 3’600 to 43'200 b/h.  Determination of an unknown beat number.  Gain control: automatic. Manually adjustable (4 levels) for watches with stray or unusual beat noises.  Diagram: presentation on a LCD graphic display. Resolution: 240 x 128 pixels. Time scale: selectable from 1 mm/ms to 10 mm/ms. Recording speed: depends on the beat number, 0.5 mm per watch beat.  Visible diagram length: 120 mm    Measuring time for numerical results: automatic or selectable from 2 s to 240 s, which corresponds to the time of 4 intervals, i.e.  28'800 = 0.5 s, 36'600 = 0.4 s. Continuous renewal of the average values every 2 s.  Display on the screen of the evaluated part of the measurement diagram.  Rate measurement: numerical display in s/d. Selectable resolution: in 1 s/d or 0.1 s/d.  Measuring range: +/- 999 s/d, respective +/- 99.9 s/d.  Amplitude: numerical display in degrees.  Resolution 1°, measuring range 80° to 360°.  Lift angle: adjustable from 10° to 90°. The lift angle can be switched off for rate measurement only. Measuring mode for watches with coaxial escapement. It ensures an accurate measurement of the amplitude.  Beat error: numerical display in milliseconds.     Resolution: 0.1 ms, measuring range +/- 9.9 ms.  Oscillogram: visualization of the beat noise allows analysis of the escapement. Nonlinear signal amplification for better visualization of low signal amplitudes. Automatic gain control for ideal resolution. 3 different time deviations: 20 ms, 200 ms and 400 ms for full screen length.  Acoustic check: loudspeaker to hear the beat noises.  Start/stop  function: enables the current screen display to be stored as long as required at any time.  RS232 port for the connection of the printer (see accessories)  -  Printout of the numerical results or a graphic printout of the displayed diagram.  -  Printout of the result table after a programmed measuring cycle by means with Micromat S   (also possible with old Micromat P or Micromat Tourbillon via Interface S1 ). - For the numerical results and the graphic files transmission the printer port of the equipment   can be connected to a PC. For it the software AutoPrint (available as accessory) is needed.  Second RS232 port for the connection of a PC or the Witschi GPS receiver.  Time base: high frequency quartz time base, OCXO. Stability: +/- 0.01 s/d between 10° and 40° C.  Display: LCD graphic display, 240 x 128 pixels, illuminated.  Casing:  Aluminium front plate, natural anodised.  Rear cover and stand: plastic, colour anthracite. Dimensions: 225 x 200 x 87 mm. Mains connection: mains adapter: 9V~, 1.2 A.  Available for 230 V~ (210 - 240 V~).
