A22I US Plug No1900 Timegrapher Watch Testing Tool Watch Tester for Repairers Hobbyists Watch Test Repairing Tool Timing Test The frequency diagram of the watch can be displayed on the LCD screen._x000D_ According to different watches, the instrument automatically adjust the optimal signal level during the test._x000D_ The instrument 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._x000D_ For the conventional be-at, the instrument can automatically respond; for the special be-at, can manually select._x000D_ The sampling period can be by 2 seconds, 4 seconds, 6 seconds, 8 seconds, 12 seconds, 20 seconds, , 60 seconds, and the average value of corresponding period 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._x000D_ Measuring possibilities: rate deviation, amplitude, be-at error of mechanical watches and diagram recording of the be-at noise._x000D_ Please note: the physical slightly color difference or difference, does not affect the use, please do not mind, thank you!_x000D_ Rate deviation measurement:_x000D_ Measuring ranges: 999s/d or 99.9s/d_x000D_ Resolution: 1.0s/d or 0.1s/d_x000D_ Amplitude measurement:_x000D_ Measuring ranges: 100~360_x000D_ Resolution: 1_x000D_ Measuring of the be-at error:_x000D_ Measuring ranges: 0.0~9.9 ms_x000D_ Resolution: 0.1 milliseconds_x000D_ Lift angle:_x000D_ Measuring ranges: 30~70_x000D_ Default value: 52_x000D_ Measure positions: 1-6 positions_x000D_ Line length: 480 points_x000D_ Measuring times periods: 2/4/6/8/12/20/30/60 seconds_x000D_ Display: color LCD graphic monitor, 480*272 pixels_x000D_ Working environment: 10~40_x000D_ Relative humidity: 0~80% RH_x000D_ Plug Type: US Plug, it applies to Canada, India, Mexico, Thailand, Taiwan, the , the Philippines and so on._x000D_ Voltage: AC100-240V_x000D_ Colour:Black_x000D_ Material:plastic+metal Package Contents:_x000D_ 1 x Timing Timegrapher Only the above package content, other products are not included._x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
