Electronic scale repeatability does not meet the requirements of metrological verification procedures

The repeatability of the electronic weighbridge does not meet the requirements, and the repeatability is excessive. The so-called repeatability refers to the consistency of the results obtained under the same conditions for consecutive measurements of the same measurement. The same conditions referred to herein refer to The same measurement conditions, that is, the same measurement procedure, the same observer, using the same measurement standard and the same location under the same conditions, repeating the measurement in a short time, the repeatability is not good for each load of the same load, and the conditions are met. Under the same measurement conditions, the magnitude of the reaction exceeds the allowable error of the metrological verification. The reason for this situation is multi-faceted, and the elimination method is basically the same as the common troubleshooting method of the aforementioned indication error.

5. The large screen of the electronic platform scale is abnormal.

When the electronic platform scales the large screen to display normal operation, the indication value information should be consistent with the meter display. Usually, there are two situations in which the large screen is faulty:

1.

A bunch of red bars appear on the big screen, and the display value is not displayed properly. The reason is that the line is faulty, that is, the connection line between the meter and the big screen is broken; the second is the connection error, usually the connection is not connected, the virtual connection Or loose; third, the large screen interface is damaged, then the large screen interface needs to be replaced; the fourth is that the interface between the instrument and the large screen is damaged. In this case, the instrument needs to be replaced or the instrument interface is repaired.

2.

There is no display on the big screen. In this case, the power supply is not connected. Second, the power fuse of the large screen is damaged or broken down. This requires replacing the fuse of the large screen. Third, the large-screen circuit board is damaged, and it is necessary to replace the new large screen or repair the circuit board.

These are just a few common faults in electronic platform scales. There are many kinds of faults in electronic platform scales. It is recommended that you use the electronic platform scales properly for proper use and maintenance, so as to reduce the failure of the electronic platform scale.
