Description: Model: M-1000 Easy to use for mechanical watch collection. This watch tester automatically calculates rate, amplitude, and beat error using readings from the microphone stand. LCD screen displayed.According to different watches, the instrument will automatically adjust optimal signal level during testing. - The LCD screen shows the readings in real time with 2 dotted lines moving across the screen to provide a visual representation of the tic tock from your watch 6 kinds of testing position can be adjusted. Amplitude level is between 275 and 315; Rate Deviation Range: 999 s/d with precision 1 s/d' The sampling period can selected by 2 , 4 , 6 , 8 , 10, 20, 30 , 60 seconds, and the average of corresponding period will be regard as the precise value of the watch. Specification: Frequency: Can be selected automatically or manually, beat frequency: 18000, 19800, 21600, 25200, 28800, 36000 Daily difference measurement: display plus or minus 999 seconds/day, and display 1 second/day within the measurement range Swing measurement: the score is 1, the range is 100 degrees to 360 degrees. Measuring average time: 2, 4, 6, 8, 10, 20, 30, 60 seconds Polarization measurement: unit millisecond, resolution 0.1 millisecond, measurement range 0.0~9.9 seconds Lift angle: range from 30 degrees to 70 degrees Voltage: AC 100V-240V Material: Plastic Size: Approx. 18x9x9cm Package Includes: 1 Set Timegrapher Note: Color might be slightly different due to the color calibration of each individual monitor.
