WeiShi No.1900 Multifunctional Professional Timegrapher Precise Mechanical Watch Test Repairing

This No.1900 timegrapher is a precise mechanical watches test instrument, it is used for multi-testing by watch manufacturers and watch technician.

Features: The frequency diagram of the watch can be displayed on the LCD screen. According to different watches, the instrument will automatically adjust the optimal signal level during the test. The instrument will automatically calculate the rate deviation, amplitude, be-at error, and display them by the data in real time; select "+/-99.9s/d" at item rate ranges for result display, which can make the accuracy of rate deviation up to 0.1s/d. For the conventional be-at, the instrument can automatically respond; for the special be-at, can manually select. The sampling period can be selected by 2 seconds, 4 seconds, 6 seconds, 8 seconds, 12 seconds, 20 seconds, 30 seconds, 60 seconds, and the average value of corresponding period will be regarded as the precise value of the watch. Six kinds of testing positions can be adjusted, and the simulation sound can be played in the speaker or mute.

Specifications: Plug: EU-plug, US-plug, AU-plug (optional) Main material: ABS Color: grey+black Measuring possibilities: rate deviation, amplitude, be-at error of mechanical watches and diagram recording of the be-at noise. Rate deviation measurement: Measuring ranges: +/-999s/d or +/-99.9s/d Resolution: 1.0s/d or 0.1s/d Amplitude measurement: Measuring ranges: 100 degrees ~360 degrees Resolution: 1 degrees Measuring of the be-at error: Measuring ranges: 0.0~9.9 ms Resolution: 0.1 milliseconds Lift angle: Measuring ranges: 30 degrees ~70 degrees Default value: 52 degrees Measure positions: 1-6 positions Line length: 480 points Measuring times periods: 2/4/6/8/12/20/30/60 seconds Language: Chinese, English, Japanese Display: color LCD graphic monitor, 480*272 pixels Working environment: 10 celsius ~40 celsius Relative humidity: 0~80% RH Item size: 185 * 120 * 40mm / 7.3 * 4.7 * 1.6in Item weight: 337g / 11.9ounce Package size: 230 * 210 * 195mm / 9.1 * 8.3 * 1.6in Package weight: 1379g / 3.0lb Packing List: 1 * Timegrapher 1 * Timegrapher Sensor 1 * Power Cable 1 * User Manual
