II Performance 2.1 Time
The machine can measure the natural parting and closing time of 12 metal fractures, the same period time, the same period time, the same period time, the gold short time, the no flow time, the closing spring time of the process of closing - parting, dividing - parting and dividing - dividing; Some models can measure the pre-casting time of closing resistance.
2.2 Speed and stroke
This tester can record and measure the closing bounce time, the number of bounces, the bounce process, and the bounce waveform of each fracture.
2.3 Speed and stroke
This tester can record and calculate the rigid points, rigidity, maximum speed, average speed, total travel, opening distance, over travel, rebound amplitude, time-travel characteristic curve.
2.4 Current and voltage
This tester can record the opening / closing current value and current waveform of the opening / closing coil, and provides DC5 ~ 270V / 10A (20A) digital adjustable circuit breaker operation power supply, automatically completes the low voltage operation test of the circuit breaker, and measures the open circuit. The operating voltage of the device.
2.5 Closing resistance
Some models of this machine can measure 6-way closing resistance value and its pre-throw time at the same time.
