Usually, the terminal pins of a 3266 potentiometer consist of three pin contacts, one movable pin and two fixed pins.
However, during installation and wiring, the two fixed pins can be interchanged, while the middle fixed pin cannot be interchanged with the movable pin,
otherwise it will cause incompatibility between the wires and may directly damage the potentiometer.
The adjustment method of 3266 potentiometer can be achieved by inserting a flat screwdriver into the screw adjustment port,
and then turning the screwdriver can change the orientation of the chip, thereby controlling the adjustment of resistance value

Application of WEET trimming potentiometers
Potentiometers are widely used and can be applied in many products. In power supply products such as switching power supplies, UPS power supplies, high-frequency switching power supplies, reverse frequency power supplies, chargers, frequency converters, etc., blue and white fine adjustable potentiometers and precision potentiometers are used; In household appliances, such as induction cookers, humidifiers, air conditioners, range hoods, lighting fixtures, electric fans, and other small home appliance control boards; In communication products such as walkie talkies, cable TV equipment, mixing stations, window intercoms, etc., SMT adjustable potentiometers, iron case potentiometers, etc. are used
Audio devices: Adjustable potentiometers can be used to adjust parameters such as volume and tone in audio devices.
Lighting equipment: Adjustable potentiometers can also be used to control the brightness of lighting equipment.
Power circuit: Adjustable potentiometers can also be used to control the output voltage of power circuits

Function of potentiometer
There are many types of potentiometers, and the functions of different potentiometers may vary. However, most potentiometers have three basic functions
1. First function: current control
Some precision potentiometers are capable of current control, only in this way can the current value be accurately obtained. When the selected current output end is the sliding contact lead out end,
the potentiometer can be used to control the current size;
2. Second function: distributing voltage
By utilizing the nearly linear relationship between resistance and voltage, adjusting the resistance value can adjust the voltage distribution relationship and achieve stepless output voltage regulation,
such as in humidifiers and other areas;
3. The third function is to change the resistance
When the input parameter of the circuit is the resistance value, a potentiometer can be used. When the trimmer potentiometer is connected to two end devices,
it can obtain a smooth and continuous change in resistance value within the travel range. At this time, the potentiometer plays a role in changing the resistance.
For example, in humidity control, different humidity levels are displayed by controlling the resistance value.
