Feature: 1.The Timegrapher is a precise mechanical watches test instrument,it is used for multi-testing by watch manufacturers and watch technician. 2.The frequency diagram of the watch can be displayed in the LCD screen. 3.According to different watches, the instrument will automatically adjust optimal signal level during testing. 4.The instrument will automatically calculate the rate, amplitude, beat error, and display them by data in real time. 5.For the conventional beat, the instrument can automatically response; for the special beat, can manually select. 6.Six kinds of testing position can be adjusted, and the simulation sound can be play in the speaker or mute. Parameter: Beat Numbers (Frequency Numbers) 1.Automatic The following beat numbers are selected by automatic selection mode: 12000,14400,18000,19800,21600,25200,28800,36000,43200 (If the tested beat is not in automatically selection, the instrument will display the closest beat number, but the test result is not correct. At this time, use the manual mode to select the relative beat.) 2.Manual selection It can selected out the beat number that Automatic select can not identify and rare beat number. Lift Angle The lift angle is 52° for many common movements, therefore the lift angle value of instrument for factory is set to 52°. This value is required to calculate the amplitude and must be selected according to the watch movement. The lift angle can be set to between 30°and 70° Parameters: Daily rate : -999 s/d ~ +999 s/d, allowable tolerance: ±1 s/d Amplitude : 100o ~ 360o, allowable tolerance : ±1o Beat error : 0 ~ 9.9 ms, allowable tolerance : 0.1 ms Power supply : single - phase AC 110 ~ 240V ±10%, power consumption : about 10 W Package Include: 1 set of timegrapher（watch is not included）
