Timegrapher No.1000 Multifunctional Watch Tester Watch Calibration Tool Watch Timing Machine for Watchmaker Mechanical Watches 100‑240V Item Type: Watch Timegrapher Material: ABS Color: White Measurement Range: Daily difference in speed for mechanical watches, amplitude, beat error, line display of watch timing. Frequency Count: Can automatically select the beat of common watches, or manually select the beat of less common watches. Daily Difference Measurement: Display numeric ±999 seconds/day, within the measurement range displayed as 1 second/day. Amplitude Measurement: Display numerically, with a rate of 1°, measurement range 100°—360° (lift angle will affect amplitude, range is 30°—70°. Under normal circumstances, the swing amplitude of the watch should not exceed 330°) Measurement Time for Average Values: 2s, 4s, 8s, 12s, 20s, 30s, 60s. Beat Error (Frequency Error) Measurement: Numeric unit is milliseconds; resolution is 0.1 milliseconds, measurement range is 0.0—9.9 seconds. Lift Angle: The measurement range for the lift angle is 30°—70°, and the factory setting is 52°. Measurement Positions: 1—6 positions. Operating Environment: 0℃ —50℃, Relative Humidity: 0—80% RH. How e: Product Instructions: After connecting the power supply and the sensor, the instrument enters the test mode; place the watch on the sensor, the watch's crown should be against the metal piece. The test position can be arbitrarily switched. After switching, your hand should leave the sensor and watch. If the green signal light is flashing, it has received the watch signal.
