Press the calibration key gently. When CAL- appears on the display, let go, and CAL- 100 will appear on the display, where "100" is a flashing code, indicating that the calibration weight needs standard weight 100g. At this time, put the prepared "100g" calibration weight on the weighing plate, and the display screen will appear "-"waiting state. After a long time, the display will appear 100g. Take the calibration weight, and the display should show 0 grams. If it is not zero, reset it again and repeat the above calibration operation twice.

Electronic balance is a kind of balance that uses electromagnetic force to balance the gravity of a weighed object. Adopt electromagnetic balance sensor, accurate and reliable weighing, fast and clear display, automatic detection system, automatic calibration and overload protection. Electronic balance can be divided into six categories according to accuracy: ultramicro electronic balance, microbalance, semi-microbalance, constant electronic balance, analytical balance and precision electronic balance.
