Common problems in the use of electronic loadometer

Common problems in the use of electronic loadometer
1) the value is out of tolerance
Indicates that the indication error of electronic loadometer is greater than the maximum allowable error of national verification regulations. The simple error of indication is not a fault. Because any kind of measuring instrument after working for a period of time, certain performance have a certain amount of change. Electronic loadometer after installation and debugging, the various performance measurement are within the scope of permissible error, the error will change after using for a long time, there may be error is greater than the value for use in the margin of error, namely "error", it is difficult to find, for the operator only calibration measurement department personnel verification can be found in the standard weight.
2) faults caused by environmental problems
One of the main reasons is the use of electronic loadometer site environmental hygiene is poor, such as long-term weighing bulk, debris, dust into the scale under the square or crawler into the internal meter, when the damp weather, debris and dust due to moisture absorption and conductivity, causing components or circuit fault, sometimes may burn components. This type of failure is usually abnormal display.
3) sensor failure
The electronic loadometer is generally used in parallel with 4~10 sensors, and its error is generally less than 0.02%FS. The damage of the sensor is mostly caused by weighing overload, improper use or internal quality (patch, insulation, etc.) of the sensor. Therefore, the protection of sensors should be strengthened.
