How to carry out daily maintenance of electronic scales
1. Electronic scale when the need to recharge, pay attention to the external adaptation (step-down power) rated output voltage whether, with the "table" matching scale ¢6 the polarity of the plug is correct (voltage can be 10% of the positive and negative difference) also note at the beginning of the adapter is highly rated voltage 110 v and 220 v, don't make a mistake. (the no-load voltage of 9V shall be greater than 12V, and the rated power of the transformer shall be greater than 15W, and the quality of the silicon steel sheet shall be better. Otherwise, will cause the charge current.
