Weighing display is an instrument that displays the mass and weighing status of the weighed object in electronic instrument. Weighing display is originally analog indicator type, which consists of error amplifier, reversible motor, Balance Bridge, excitation power supply, Dial, Pointer and other parts, and works according to the principle of automatic balance electronic potentiometer. It has slow weighing speed, single function and low accuracy, and has been basically eliminated now. The current weighing display is digital display.
