1、 The internal code of the weighbridge weighing instrument is unstable;
The unstable inner code may be caused by poor contact or even damage of capacitors C4 (CBB474) and N8 (4011) due to moisture or other reasons. At this time, repair welding or replacement can be attempted.
2、 The weighbridge weighing instrument does not return to zero after self inspection;
Sometimes, after zeroing, the visible graduation value automatically switches during weighing due to vibration, accompanied by partial zeroing during weighing, resulting in a large stabilizing error, and the zero position displays a negative number after the weight is put down.
3、 The weighbridge weighing instrument has no response after starting up,
Press and hold the "Zero" key to start the machine and reset the range. If it cannot be set normally, there is still no range after restarting. Basically, it can be determined that the memory chip N7 (24C04) is damaged. After replacing the element, the range is reset and recalibration is required.
So Jiangmen Electronic weighbridge manufacturer Lidong Weighing Instrument suggested that no matter what kind of aging of electronic weighbridge instrument is caused, it should be improved. Otherwise, it will be too late when the instrument of the electronic weighbridge has obviously aged. Therefore, when you use the electronic scale, you should pay more attention to maintenance, check the parts, and make the parts work normally, so that the aging phenomenon will not occur later.
