Performance characteristics:

1. Time measurement (6 channels): closing time; Opening time; Secondary opening time (reclosing operation) and closing bounce time; The advance input time (coordination time) and exit time (lag time, most switches do not have this parameter) of the fracture closing resistor; Three phase synchronization time of fracture surface; Single phase synchronization time of fracture surface; The coordination time between the auxiliary switch contact and the main fracture surface; Combination and division time (golden short time); Splitting and merging time (no flow time).

2. Displacement measurement (1 channel): capable of measuring the mechanical stroke characteristic curve; Travel itinerary, overtravel, and opening distance; Rebound stroke (vacuum circuit breaker); Overstroke itinerary.

3. Measuring current: closing and opening current.

4. Measurement auxiliary contacts: 1 normally open and 1 normally closed (passive contacts).

5. Speed measurement: speed, maximum speed.

6. Large capacity storage function: measurement data storage>900 times, switch model storage>200.

7. Built in 15A DC voltage power supply: adjustable from 36V to 265V, capable of conducting low voltage switch operation tests.

8. External triggering can be used for closing and opening measurement: External triggering signal: AC/DC 30V-300V.

9. Can input external DC voltage power supply for switching operation: DC 30V-300V.

10. Speed definition and the speed of any segment can be set.

11. It can display the opening and closing time, current, displacement waveform curve and measurement data of the fracture, and can read data at any point on the curve.

12. Automatically generated data and waveforms can be printed.

The maximum sampling time is 1.5 seconds.
