Function

1. Control box Panel

    

   1、Ground terminal: When testing, the grounding terminal of control box and      high-voltage cylinder should be connected together, and then connected with the earth.

   2、Output port  is used for  the connection  of the control box and high-voltage cylinder . We only rotate the cable pressing plug clockwise in place when connecting, only rotate the cable plug anti-clockwise when broking.

   3、Voltage setting  switch: Used for setting the over-voltage protection value. The display unit of dial switch is kV, set values is 1.1 times of the test voltage.

   4、Power input socket: A random configuration of power line and the power input socket. (AC voltage 220V±10％, socket with fuse.)

   5、Digital voltage meter: Digital display high voltage DC output voltage.

   6、Digital current meter: Digital display high voltage DC output current.

   7、Power switch: Forward press, the power is on, the red lights, conversely to shutdown.

   8、Yellow light button: This function is designed for zinc oxide arrester for measurement of 0.75UDc1mA. It’s effective when the green lights. After pressing the button, output voltage reduce to the original 0.75%, and keeps this state. Press the red button, red light and green light all out, high pressure cuts off and exits 0.75 times state.

   9、The green button: High-voltage output button, high voltage indicator lamps. In red light state, press the green button, the green light and red light out, this means high voltage circuit is switched on, then we can raise voltage. It’s Effective that this button must be on voltage regulating potentiometer zero state. If press the green button, the green light is bright red, at the same time the red light is brighter, but release the green button, green light out and red light, it means Internal protection circuit has been working.

   10、Red button: the red light  shows that the power is switched on and the high voltage is cut off .In the green state ,press the red button, red light is bright, high voltage is cut off.

   11、Voltage adjusting potentiometer: The potentiometer is a multi-turn potentiometer. Rotate clockwise to boost, and conversely to Step-down. The potentiometer has the function of controlling electronic zero protection, so must firstly return to zero before boosting.
