This No.1000 timegrapher is a precise mechanical watch test instrument that is easy to use and more professional. It is a watch tool that can be used for both repairers and hobbyists. 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. 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 exact value of the watch. Six kinds of testing positions can be adjusted, and ana-log sound can be played in the speaker or mute. Specifications: Plug: EU-plug, US-plug, AU-plug (optional) Main material: metal Color: grey+black Measuring possibilities: rate deviation, amplitude, be-at error Rate deviation measurement: the ranges of deviation is ±999 sec/day, accuracy is 1.0 sec/day Amplitude measurement: numerical display in degrees, resolution is 1°, measuring ranges is 100° to 360° Measuring for the be-at error (frequency error): numerical display in milliseconds. Resolution is 0.1 milliseconds; the measuring ranges is 0-9.9 ms Measuring position: 1 to 6 positions Sampling periods: 2/4/6/8/12/20/30/60 seconds Lift angle: 30° to 70°, default is 52° Line length: 196 points Language: Chinese, English, Japanese Display dimensions: 98 * 34mm / 3.9 * 1.3in Item size: 172 * 114 * 40mm / 6.8 * 4.5 * 1.6in Item weight: 1400g / 3.1lb Package size: 200 * 150 * 80mm / 7.9 * 5.9 * 3.1in Package weight: 1483g / 3.3lb Packing List: 1 * Timegrapher 1 * Microphone 1 * Power Cable 1 * User Manual
