The correct way to buy electronic scales
When purchasing the electronic scale, the maximum weighing quantity and the minimum weighing quantity and the area of ​​the object to be weighed should be determined first, and then the error value of the promised value. The verification scale value of the electronic scale should be less than the error value of the promised, so that accurate weighing results can be obtained. Some electronic scales cost a few hundred yuan, the scale value e = 10d, as very accurate, in fact, the error is very big, let alone the accuracy. For example: the maximum weighing 3000g minimum weighing 10g, the verification graduation value 0.5g, the apparent graduation value 0.1g, for example, the article said above shows 326.1g, 0.5g is the exact value, 0.1g is not accurate.
The electronic scale is attributed to the three-level scale, the division number is 2000-10000, and the maximum weighing quantity divided by the division number is the verification division value e. The verification division value is the tolerance value when the measurement detection part verifies whether the measurement function of the scale is qualified, and is divided into several test segments, and the tolerance value is also different. The apparent scale value of the electronic scale is the minimum apparent value d (subdivided value) of the scale, and the apparent scale value does not represent the metering accuracy.
When purchasing the electronic scale, pay attention to the minimum weighing. For example, the minimum weighing is 10g, which means that the item you are weighing is larger than it, and the indication value of the electronic scale is accurate.
