A. Debugging method for multi turn precision adjustable potentiometer
1. Correct connection of input signal source
First, connect the signal wire of the input signal source to the middle pin of the potentiometer, and then connect the output end to the load.
2. Resistance adjustment of potentiometer
When debugging a circuit, the resistance of the potentiometer should be adjusted to a smaller value first. Once the resistance value is determined, it can be gradually increased.
3. Offset calibration of potentiometers
When using a potentiometer, there may be unstable situations where the potentiometer drops or rises, and offset calibration is required.
B. Precautions for multi turn precision adjustable potentiometers
1. Multi turn precision adjustable potentiometers should avoid exceeding the rated voltage and current.
When debugging the circuit, attention should be paid to the polarity and wiring of the power supply to avoid short circuits and power damage.
During the debugging process, the sliding trajectory of the potentiometer may cause wear and tear, and attention should be paid to protection.

Detailed explanation of the three pin connection method for multi turn precision adjustable potentiometers
1、 Introduction to Multiturn Precision Adjustable Potentiometers
Multi turn precision adjustable potentiometer is a commonly used electronic component used to adjust linear voltage and current in circuits. It has high accuracy, reliability, and is suitable for various circuits, and is widely used in the electronics industry.
2、 The connection method of the three legs of a multiturn precision adjustable potentiometer
The three legs of a multi turn precision adjustable potentiometer are the middle leg, sliding leg, and fixed leg. According to different needs, the middle foot and sliding foot can be connected to the circuit separately, and the fixed foot is usually used for power or ground.
A. Single circle connection method
The single loop connection method is to connect the sliding foot and the middle foot together, and fix the foot to ground or power. This connection method is suitable for single voltage circuits, such as audio amplifiers, power amplifiers, etc.
B. Double circle connection method
The double loop connection method is to divide an adjustable potentiometer into two parts, connect the two fixed pins together, and at the same time connect the middle pin and the two sliding pins to two separate circuits. This connection method is suitable for circuits that require two different voltages or currents, such as power amplifier front-end circuits.
C. Three circle connection method
The three circle connection method is to divide an adjustable potentiometer into three parts, connect two sliding pins and one fixed pin into one circuit, and at the same time connect the middle pin and the other fixed pin to another circuit. This connection method is suitable for situations that require two different voltages or currents, such as audio frequency EQ circuits.

Precautions for using WEET potentiometers:
(1) In order to prevent the pin contacts and conductive layer of the WEET potentiometer from deteriorating or burning out, the working current of the potentiometer should not exceed the rated current.
To avoid potential damage to the potentiometer.
(2) If the WEET potentiometer is used for a long time, there may be some loud noise or inflexible shaft adjustment.
In this case, there may be a lack of specialized lubricating oil inside the potentiometer.
By adding appropriate lubricating oil, the two types of faults can be solved.
(3) Do not tap or shake the WEET potentiometer during installation. Because the interior of the potentiometer is composed of various components,
it is possible that these components may fall off due to violent shaking or vibration. So, more precautions are needed for this.

Suggestion for storing WEET potentiometers:
(1) Avoid storing WEET potentiometers and items with chemical components to prevent them from corroding the internal components of the potentiometer.
So it should be isolated and stored from items containing these chemical components.
(2) WEET potentiometers should be stored in high temperature environments, as storing them in high temperature areas may cause accidents such as spontaneous combustion of internal components.
So it should be stored and not placed in a high temperature place.
(3) WEET potentiometers should not be stored in damp places, as storing them in damp places can easily cause the internal components of the potentiometer to become damp and fail.
So the WEET potentiometer should be stored in a ventilated place.
