The structure, accuracy, stability, surface treatment, anti-corrosion, waterproof, explosion-proof, and application in special industries of Youbao Company's weighing products have unique industry advantages and have obtained multiple national patents., Do you know how to repair a truck scale when it malfunctions?

1. The small tonnage loading display is normal, but when it approaches half of the scale, the weight value suddenly increases. This phenomenon is mostly caused by the gap between the longitudinal limit bolt and the top plate being too small. When the load increases, the longitudinal bolt presses against the top plate, generating a directional force that causes the displayed value to suddenly increase.

2. Small tonnage loading is normal. After increasing the load, the displayed value significantly decreases. This phenomenon may be due to the contact between the protective cover of the weighing sensor and the weighing platform or improper adjustment of the load limiting device of the weighing sensor, which prevents the weight from being fully added to the weighing sensor.

3. There is a heavy object on the weighing platform, but the display is still "zero". The possible reason is:

The function keys of the weighing display controller are used incorrectly and are not in the weighing display state. It may be that the total output line of the weighing sensor is not in contact with the connector of the weighing display sensor

4. The scale platform is not flexible and the ballast does not match the display. There is filling material in the gap between the scale body and the slope (or between the scale pits), which connects the scale platform to the ramp (or pit body) and affects weighing.

5. The displayed value after loading is significantly lower than the load value. Usually, there is a malfunction in the excitation power supply of the weighing sensor.

6. After power on, the display flashes a fixed character shape and does not measure. Generally, the output signal of the weighing sensor is short circuited to the shielding layer, causing the weighing display controller to input a large signal and experience overload. A multimeter can be used to measure the resistance between the sensor and the shielding layer, as well as between the sensor and the ground wire, to identify and eliminate the short circuit.

7. The printer is not turning and cannot work. Caused by poor printer connectors.
