1, at this time, we should first determine the 110V/220V of the electronic hook scale, whether the voltage switching switch is transferred to the same voltage as the use of the power supply, and check whether the charging line is firmly inserted on the charging seat on the scale, and keep in mind that a socket can not be used together with other electrical machinery;

2, if the above steps are all belonged to. Normal, we need to check whether the product's charging line is broken because of external factors that cause the product to appear when it is charged.

3, check the electronic hook scale check fuse is normal, prevent the voltage instability, cause the fuse to be burned;

 4, check the electronic hook scale battery is normal, or because The quality of the electronic hook scale has no response to charging.
