WeiShi No.1900 Timegrapher Watch Tester for Repairers Frequency Diagram Rate Deviation Amplitude Be-at Error Measurement

Features 1 The frequency diagram of the watch can be displayed on the LCD screen 2 According to different watches the instrument will automatically adjust the optimal signal level during the test 3 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 4 For the conventional be at the instrument can automatically respond for the special be at can manually select 5 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 6 Six kinds of testing positions can be adjusted and the simulation sound can be played in the speaker or mute Specifications No 1900 Plug EU plug US plug optional Main material ABSColor grey blackMeasuring 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 dAmplitude measurement Measuring ranges 100° 360°Resolution 1°Measuring of the be at error Measuring ranges 0 0 9 9 msResolution 0 1 millisecondsLift angle Measuring ranges 30° 70°Default value 52°Measure positions 1 6 positionsLine length 480 pointsMeasuring times period
