Capacitor detection methods are divided into three main categories: variable capacitor detection, electrolytic capacitor detection, fixed capacitor detection.


Detection of variable capacitors


A .with the hand gently rotates the axis, should feel very smooth, should not feel sometimes lose when tight or even has the phenomenon of stagnation. The rotation shaft should not be loosened when the load axis is promoted, back, top, bottom, left, right and other directions.


B .use one hand to rotate the axis, the other hand to affect the outer edge of the film group, should not feel any loose phenomenon. Variable capacitors with poor contact between the shaft and the moving plate can no longer be used.
