No.1900 Timing Timegrapher Mechanical Watch Timing Tester (us Plug)

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: US-plugMeasuring 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/dResolution: 1.0s/d or 0.1s/dMeasuring ranges: 100~360Resolution: 1Measuring ranges: 0.0~9.9 msResolution: 0.1 millisecondsMeasuring ranges: 30~70Default value: 52Measure positions: 1-6 positionsLine length: 480 pointsMeasuring times periods: 2/4/6/8/12/20/30/60 secondsLanguage: Chinese, English, JapaneseItem size: 185 x 120 x 40mm / 7.3 x 4.7 x 1.6inPlug Type:US Plug,it applies to Canada, India,Mexico, Thailand, the United States, the Philippines,Taiwan and so on.Color: grey whiteMaterial: Metal+PlasticPackage Contents:1 x Timegrapher1 x Power CableOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
