The volume control of stereo audio amplifier can choose double coaxial potentiometer; The tone control of sound system can choose the direct slide potentiometer; The reference voltage of the power supply circuit should be adjusted by the trimmer potentiometer; The potentiometer used in communication equipment and computer can choose patch type multi-turn potentiometer or single-turn potentiometer.The detection of the nominal resistance value, measurement, the selection of multimeter resistance file appropriate range, the two pen respectively connected in the potentiometer two fixed pins between the weld, the first measurement of the total resistance value of the potentiometer is the same as the nominal resistance value. If the measured resistance value is infinite or larger than the nominal resistance value, it indicates that the potentiometer has been open circuit or variable value damage.
