Specifications 1,a precise mechanical watches test instrument 2,frequency diagram of the watch can be displayed in the LCD screen 3,quality The multifunction Timegrapher No.1900 is a precise mechanical watches test instrument, it is used for multi-testing by watch manufacturers and watch technician. The frequency diagram of the watch can be displayed in the LCD screen. According to different watches,the instrument will automatically adjust optimal signal level during testing. The instrument will automatically calculate therate,amplitude,beat error,and display them by data in real time. For the conventional beat,the instrument can automatically responds;for the special beat,can manually select. The sampling period can selected by 2 seconds, 4 seconds, 6 seconds, 8 seconds, 12 seconds, 20 seconds, 30 seconds, 60 seconds, and the average of corresponding period will be regard as the precise value of the watch. Six kinds of testing position can be adjusted,and the simulation sound can be play in the speaker or mute. This timing machine will automatically calculate in real time for the following: -beat rate -Amplitude -beat error -beat number Measuring possinilitied: Rate deviation, amplitde, beat error Rate deviation measurement: the range of deviation is ± 999 sec /day, precision 1.0 sec/day. Amplitude measuremet" Numerical display in degrees, resolution is 1°, measuring range: 100° to 360° Measuring for the beat error (frequency error): Numerical display in milliseconds. Resolution is 0.1 milliseconds; the measuring range is 0-9.9ms. Measuring position:1 to 6 positions Line Length:196 points Language: Chinese, English, Japanese Supply voltage: single-phase AC 100V~240V ±10% two-line Display dimensions:95*54mm Dimensions:185*130*95mm Weight: 3.5kg
