Why is there no display for weighing after zeroing

Below we will discuss the issue of why weighing is not displayed after zero setting.

1. The main board of the weighing scale is aging.

2. The scale does not have a self checking zero response after startup. In this case, we can reset it again. The steps during this process are to press and hold the zero button to turn on the power, and then set the range again. However

If the setting cannot be made, there will be no range after restarting, and it can be concluded that the storage chip will be damaged. Our solution to this situation is to install a new chip for calibration.

3. The software of the weighing scale is not updated in a timely manner, so remote control reception of old weighing scales can cause interference with the settings of the single chip. After self checking, it does not reset to zero, but occasionally after resetting, it may appear

The change in division value caused by vibration can result in a large error. After removing the weighed item, negative numbers will appear.

4. The instability of the internal code of the weighing scale and the display of AD on the hold key during startup. If it cannot jump to the internal code value, the internal code will not be stable. This is because the weighing scale has been in a damp environment for a long time

In case of damage caused by poor contact or environmental conditions, the internal code of the weighing scale can be replaced.
