First adjust the DC-AC converter so that the secondary voltage of B1 is above 200V, and should not be lower than 160V when connected to a 39k load. After the whole machine is connected, the ZD flashes, and the high-voltage pulse transformer makes a "pop, pop" sound. Connect the voltmeter between the anode and cathode of the thyristor, and the maximum swing of the meter should be close to 150V. The oscillation period of the multivibrator should be synchronized with the C2 charging period, that is, the pulse of the multivibrator should trigger the thyristor when the C2 is fully charged. This can be achieved by repeatedly adjusting the values of R2, C2, and C3 so as to synchronize as much as possible to obtain the best output. After adjustment, the high-voltage pulse frequency is between 60-110 times per minute.
Using a high-voltage generator and a rechargeable battery to produce a strong electric shock of more than 40,000 volts, the offender will have a strong feeling of electric shock, the whole body will be numb, the body will be weak, and the ability to do evil instantly will be lost. The working principle of this high-voltage and low-current is Will not cause any harm. Use it close to the human body or aim at the other side.
