(3) what power source frequency changes to output voltage to manostat is video
The syntonic frequency of manostat of saturation of our country magnetism is power source frequency, namely 50HZ, change of permission power source frequency must not exceed ± 0.5HZ, when change of power source frequency achieves ± 1HZ, tube current wants metabolic ± 20% the left and right sides, this should cause enough attention. Accordingly, discover when machine of use X ray tube current often has flabby appearance, whether is Lv of take an examination flabby place causes power source frequency.
