Hipot Tester Calibration Steps

1. Tester output voltage:

 
                                            Figure 5  Output voltage calibration wiring diagram 
        Put the withstand voltage tester in the "reset" state, turn the "voltage adjustment" knob counterclockwise to the bottom, and connect the wires according to Figure 5. Press the "start" button and adjust the "voltage adjustment" button to make the reading of the high-voltage meter the value of the detection point shown in Table 3, and calculate whether the error between the indicated value and the reading of the high-voltage meter meets the technical indicators. If not, adjust the corresponding potentiometer value. 
                                                                      Table  3

Note: Different output voltages should be selected with appropriate high-voltage meter measurement range. The error of the high-voltage meter should be within ±1.5%. If it is a pointer-type high-voltage meter, its measurement range should be above 1/3 of the scale.

      Set the withstand voltage tester to the "reset" state, turn the "voltage adjustment" knob counterclockwise to the bottom, connect according to Figure 6, and set the "leakage current range"  switch to 2mA. Select the corresponding load resistance according to Table 4.
