The structure, precision, stability, surface treatment, anti-corrosion, waterproof, explosion-proof, and the application in special industries have unique industry advantages, and has obtained a number of national patents. When the truck scale breaks down do you know how to repair it
1, small tonnage loading display is normal, close to 1/2 scale, weighing value display suddenly increased. This phenomenon is mostly caused by the gap between the longitudinal limit bolt and the roof is too small. When the load is increased, the longitudinal bolt supports the roof and produces directionfinding jacking force, resulting in a sudden increase in the display value.
2. Small tonnage loading is normal. When the load is increased, the display value decreases obviously. This phenomenon may be caused by the contact between the protective cover of the weighing sensor and the scale platform or improper adjustment of the load limiting device of the weighing sensor, so that the weight cannot be added to the weighing sensor completely.
3. There is a heavy object on the scale platform, but the display is still "zero". The possible reasons are as follows:
The function key of the weighing display controller is used incorrectly and is not in the state of weighing display. It may be that the total output line of the weighing cell is not in contact with the connector of the weighing display cell
4, scale shaking is not flexible, ballast is not consistent with the display. There are fillers in the gap between the scale body and the slope protection (or between the scale pit), so that the scale platform is connected with the ramp (or pit), affecting the weighing.
5. After loading, the display value is much lower than the load value. Generally, the excitation power of the weighing sensor fails.
6. After power on, the display flashes a fixed glyph and does not measure. Generally, the output signal of the weighing sensor is short connected with the shielding layer, so that the weighing display controller inputs a large signal and overload occurs. The multimeter can be used to measure the resistance value between the sensor and the shielding layer and the ground wire, so as to find out the short circuit and eliminate it.
7. The printer does not work and cannot work. Printer connector is not good.
