Measuring times periods: 2/4/6/8/12/20/30/60 secondsДisplay: color LCD graphic monitor, 480*272 pixels

Measuring possibilities: rate deviation, amplitude, beat error of mechanical watches and diagram recording of the beat noise. Power supply: single-phase AC 100VпЅћ240V в‘0% two-wire Six kinds of testing positions can be adjusted, and the simulation sound can be played in the speaker or mute. 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. The instrument will automatically calculate the rate deviation, amplitude, beat error, and display them by the data in real time select 'в™9.9s/d' at item rate range for result display, which can make the accuracy of rate deviation up to 0.1s/d.ДЇor the conventional beat, the instrument can automatically respond for the special beat, can manually select. The frequency diagram of the watch can be displayed on the LCD screen.ДЄccording to different watches, the instrument will automatically adjust the optimal signal level during the test. This No.1900 timegrapher is a precise mechanical watches test instrument, it is used for multi-testing by watch manufacturers and watch technician.
