NC-3 type withstand voltage tester calibration device

The new "Verification Regulations for Pressure Testing Machines" promulgated by the state are many different from the regulations implemented in the past. In order to facilitate the measurement department to implement the new regulations. We developed the C-type withstand voltage machine calibrator, which combines the voltage, operating current and withstand voltage time of the calibration test into one standard. During calibration, the high-voltage line of the tested withstand voltage testing machine is connected to the voltage measurement terminal of the C-type calibrator. or current measurement terminal, and then select the test item and range to perform calibration. There is no need to add other instruments and wiring. It is very convenient and simple to use. Time measurement: As long as the withstand voltage testing machine is started, the C-type calibrator can automatically start time measurement. Short time settings such as seconds can be accurately measured. Compared with similar machines at home and abroad, the biggest advantage of type C machine is that it has its own load and is designed with two levels of resistance and resistance. It is also equipped with a fine-tuning resistor to adjust the operating current finer and more accurately.
