Potentiometer, a variable resistor. Generally consists of a resistor body and a rotating or sliding system, that is, a moving contact moves on the resistor body to obtain part of the voltage output. According to the introduction of the electronic components recycling company, potentiometer detection usually has the following two methods: For potentiometers with switches, in addition to the nominal resistance and contact conditions of potentiometers, the switch should be tested for normal operation. Rotate the potentiometer shaft handle first to check whether the switch is flexible and whether it has a crisp “click†when it is turned on or off. Use a multimeter R&TImes; 1Ω file, two pens on the two external pads of the potentiometer switch, respectively, turn the potentiometer shaft handle, make the switch connected, the resistance value indicated on the multimeter should be changed from infinity to 0Ω. Turn off the switch again, and the pointer of the multimeter should return to “∞†from 0Ω. During measurement, the potentiometer switch should be turned on and off repeatedly to observe the reaction of each action of the switch. Electronic component recycling company stated that if the resistance of the switch in the “on†position is not 0Ω and the resistance in the “off†position is not infinite, the switch of the potentiometer is damaged. With the appropriate range of the multimeter's resistance file, measure the resistance values ​​of the two potentiometers on the double potentiometer and whether they are the same as the nominal resistance. Then, short-circuit the potentiometers A, C'''' and the potentiometers A'''', C respectively with a wire, and then use a multimeter to measure the resistance values ​​between the center heads B, B'''', in an ideal situation. Next, regardless of where the potentiometer's shaft turns, the resistance between the two points B and B'''' should be equal to the resistance between A, C or A'''', C''''. value. Electronic component recycling company said that if the indicator of the multimeter is deflected, it indicates that the potentiometer has poor synchronization performance.
