1. Power Socket: AC 220V power supply for the instrument;
2. Fuse Holder: Fuse holder for the AC 220V power supply system;
3. Ammeter: Output current indicator (mA);
4. Voltmeter: High-voltage output voltage indicator (kV);
5. High-Voltage Indicator Light: This light illuminates when there is high-voltage output; pressing this button turns it off when there is no high-voltage output;
6. Power Switch: "Position 1" turns on the AC 220V power supply; "Position 0" turns off the system power;
7. Voltage Adjustment: After starting the equipment, first turn this knob counterclockwise to the end until the high-voltage indicator light illuminates. Then, adjust clockwise to increase the output high voltage, and counterclockwise to decrease it;
8. Zero Adjustment: Rotate the zero adjustment knob until the galvanometer reads zero;
9. Balance Adjustment: Adjust the balance knob until the galvanometer shows a noticeable deflection and reads zero. (If the pointer deflects to the left, rotate clockwise; if it deflects to the right, rotate counterclockwise). Observe and record the reading P1;
10. Adjust the amplification factor: Rotating counterclockwise decreases the amplification factor, rotating clockwise increases the amplification factor;
11. Galvanometer: The electrical balance zero point is adjustable;
