China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

High pressure sodium ballasts and metal halide ballasts need match with high voltage capacitors .Inside the power in the first capacitor is discharged (that is, the capacitor poles shorted), and then dial pointer multimeter resistance profile to 1K file with the two respectively connected to the two poles of the capacitor, see  first go to the table to the right and then slowly go to the left side of the table has been shifted to infinity, and do not turn back, then discharge the high voltage capacitors  and the positive and negative swap it over and then repeat the above process, if the same thing is good, if the pointer is not left to return to the table infinity Description leakage.
