Power supply voltage: single-phase AC 100V—240V±10% two wires.Measurement direction: 1-6 directions.Use environment: 0℃ -50℃, relative humidity: 0-80%RHShell: light gray plastic shellSize: 173×9.5×11.5mmHandling of common faults8.1 The screen does not light up after plugging in the power supply, check whether the power indicator light is on8.2 After turning on the instrument, the beep of the instrument enters the test state. After the sensor is installed and the watch is placed, the instrument does not workCheck whether the watch will rotate (and the swing must be more than 100°), and whether the handle (faucet) of the watch touches the metal piece of the sensor.8.3 The signal light will be on, but the displayed lines are messy or there are many linesThe beat may be wrong, you can manually adjust the beat (frequency) to match the watch
Measuring range: the daily difference, swing amplitude, polarization, and line display of the mechanical watch.
Number of frequencies: The beats of common watches can be automatically selected, or the less common beats can be manually selected.
Daily difference measurement: digital display ±999 seconds/day, and 1 second/day within the measurement range.
Swing amplitude measurement: digital display, the division is 1°, the measurement range is 100°-360° (the rising angle value will affect the swing amplitude, the range is 30°-70°. Under normal circumstances, the swing amplitude of the watch should not exceed 330°)
Time to measure the average value: 2s, 4s, 8s, 10s, 20s, 30s, 60s.
