Usage Notes

1. When installing the potentiometer, ensure that the axis remains in a straight line to prevent bending or deformation.
2. Protect the potentiometer from water droplets, steam, solvents, and corrosive gases.
3. External wiring should be soldered at the waist groove of the lead-out terminal. Use an electric soldering iron no larger than 45W, and the soldering time should be less than 5 seconds.
4. When applying external voltage to the potentiometer, ensure it remains within the rated power consumption range to avoid overload.
