Variable resistor movable piece can turn around. Use a flat screwdriver into the adjustment mouth is rotated, the movable contact piece on the resistive sheet can slide. Well, under normal circumstances, how do we correct it to adjust the adjustable resistance, as follows:
First, how to adjust the counterclockwise direction
Use a flat screwdriver into the adjustment port when rotating the driver clockwise or counterclockwise, the movable piece will make the appropriate rotation.
Second, how to adjust the clockwise direction
When the movable piece in a clockwise direction (the equivalent circuit of the movable piece moves down), the stator resistance increases between the 1 and the movable piece, the resistance is reduced between the movable plate and the fixed plate 2. When the movable piece is slid to the right end position (lowermost), the stator resistance value between the pin 2 and the movable piece is zero resistance between the movable piece 1 and fixed sheet maximum (equal to the nominal resistance).
When the movable piece counter clockwise (the equivalent of the movable piece moves up circuit), the stator 1 and the length of the resistor between the movable piece is reduced, the resistance is reduced, and between the stator and the movable piece 2 resistive length is increased, the resistance increases. When the moving plate is rotated to the scene left position (the top), the resistance stator l and movable piece pin between zero and 2 and the stator resistance value between the pins largest movable piece, this can equal variable resistor nominal resistance, which is equal to two fixed resistance between the sheets.
Typically, we use the movable piece must be directly connected to a lead sheet with an adjustable resistance and to be connected with the movable plate and the fixed plate 2, it can be used interchangeably between two stator pins. We believe that through the above, we have to adjust the adjustable resistance more detailed understanding.
