Generally, the electronic weighbridge will not have any fault under normal use. But if people don't follow Jiangmen Electronic weighbridge manufacturer The weighing instrument of the electronic weighbridge will naturally age after a long time of normal use.
The aging performance of weighing instrument of electronic scale can be divided into three categories. The first is the aging of the whole machine at normal temperature, the second is the aging of the whole machine at high temperature, and the second is the aging of the whole machine at high temperature with simulated load. Power on aging of the whole machine at normal temperature is a complete conversion, which is not easy to be damaged. The aging phenomenon will naturally occur after the machine has been used for a long time. However, the high temperature whole machine is powered on and the high temperature whole machine is powered on and aged with a simulated load. Both of these situations are caused by the poor carrying environment after the current passes through, which leads to the aging of the instrument. What should we do when the electronic weighbridge weighing instrument is aged? The following is the solution provided by Lidong Weighing Instrument, a Jiangmen electronic weighbridge manufacturer
1、 Internal code of 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. This test can be repaired or replaced.
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.
No matter what kind of condition causes the aging of electronic weighbridge instrument, it needs to be improved and prevented in advance. Otherwise, it must be too late when the electronic weighbridge instrument has obvious aging phenomenon. Therefore, the solution is to pay more attention to maintenance when using the electronic scale, check the parts and ensure the normal use of the parts and ensure that the aging phenomenon will not occur in the later period.
