If the balance of 1% is used for weighing, this is normal. Moreover, I have bought gold ornaments before, and the service staff also told me that 0.0 1 is an allowable error. The error loss of 0.0 1 is around 3 yuan, and there is not much loss. But some gold processing shops will tell you that the error is 0. 1, so you should be on your guard at this time.
