1.It is suitable for SF6 switch, GIS combination electric appliance, vacuum switch and oil switch of all types of metal contacts produced at home and abroad.

2. Linear stroke sensor, rotary sensor, convenient and simple installation.

3. Large screen host, straight-through type, background light LCD, contrast electronic adjustment. All Chinese menu prompt operation, switch action once, display all data and waveform.

4. The host machine can store the test results of several groups of field division and closing, and the real-time clock in the machine is convenient to save the test date and time.

5.Built-in fast micro printer, print all data and waveform.

6.The instrument has a powerful data analysis function, and can effectively analyze the parameters of the breaker's mechanical characteristics.

1. Time: the inherent parting and closing time of 12 ordinary metal fractures. The same period.

2. Reclosing: closing - parting, dividing - parting, dividing - closing - parting for each fracture: one minute, one minute, two minutes, golden short time, no current time value.

3. Bounce: closing bounce time, bounce times, bounce process and bounce waveform of each fracture;The splice rebound amplitude of each fracture.

4. Speed: just part, just combine speed, maximum speed, time-stroke characteristic curve

5. Current: dividing, closing coil dividing, closing current value, current waveform.

6. Operation voltage: DC30 ~ 250V / 20A digital adjustable circuit breaker operation power is provided in the machine to automatically complete the low-voltage operation test of the circuit breaker and measure the operation voltage value of the circuit breaker
