What is the reason why the electronic scale cannot be charged?

Below, Shanghai Shirun will analyze the reasons for this:

1Firstly, determine the lifespan of the battery to see if it has aged and is no longer usable.

2Check if the AC power supply has voltage, if there are any issues with the power socket, or if the power cord is damaged.

3If the transformer is damaged, replace it and test again. If the transformer fuse is normal, test the AC output of the transformer,9VNormal, the rectification and voltage stabilization circuit on the circuit has malfunctioned. In the case of not using the electronic scale for a long time, it is necessary to use it every3Charge the protective battery once a month.

4When the electronic scale is out of power, there will be a low voltage alarm light. If there are multiple alarms, it is likely that it is damaged due to severe power shortage. We need to replace the battery.

5The fuse is burnt out. First, check it with a digital multimeter2KThe two pins of the power cord for gear testing are displayed on the multimeter500Left or right or1.100Left and right indicate that the transformer is normal. If there is no resistance, it is possible that the fuse has blown.
