The main functions and features:

1, Accurately measure to all kinds of circuit breaker the various types of mechanical characteristic parameters

2, Simple operation, convenient connection wire, full Chinese interface, strong anti-interference ability, measurement process is fully automated and comes with DC operating power supply and software based on WINDOWS platform support, build a circuit breaker mechanical characteristics testing data for the user database.

3, Using high-performance digital signal processor (DSP) and programmable logic devices (CPLD), extensive use of surface encapsulation of components, so as to further improve the reliability of the instrument and anti-interference ability, fracture can resist the site induction tens of thousands of volts of high voltage.

4, Automatic waveform zoom function, according to the length of the trip, divide-shut brake time size, automatically set the appropriate X, Y coordinates calibration.
