Quantitative packaging scales are frequently used in daily life. How should they be adjusted when they are overloaded?
Place 10kg weights respectively at the two supporting points of the weighing hopper. When the weighing display shows "positive difference", the sensor output should be adjusted in the lowering direction; when the weighing display shows "negative difference", the sensor output should be adjusted in the raising direction. For example: When the output of the L/C-1 sensor decreases, rotate the set of fine-tuning resistors (with an original value of 10 ohms) to the left by the same amount. Rotating to the right (clockwise direction) reduces the resistance value and increases the display value (denoted as "increase").
