1. Connection
The specific wiring of the verification device of the circuit breaker tester: the red terminal of the calibration device is connected to the closing + of the internal DC output power of the high voltage switch tester, the black terminal is connected to the negative of the internal DC output power of the high voltage switch tester, and the green is connected to the high voltage switch for testing. The internal DC output power supply of the instrument is open +.
2. Calibration
There are two miniature plastic circuit breakers on the side of the verification device of the circuit breaker tester. One is used to calibrate the switch time bounce parameter, and the other is used to calibrate the stroke speed. After the time bounce switch is turned on, the time bounce and other parameters of the high voltage switch tester can be verified. After the switch of the stroke speed platform is turned on, it is necessary to wait for the built-in computer driver to fully start before it can be operated. The whole process is about 30 seconds.
3. Set parameters
①Calibrate the specific setting and operation of the time parameters of the high-voltage switch tester:
Calibration device setting: trigger mode: external trigger
Trigger type: active trigger
Pulse output: node output
②Settings of the calibrated high-voltage switch tester: trigger mode: internal trigger
Output voltage: can be adjusted between DC110-DC220V
