The division value of the electronic balance is mainly: the calibrating value E and the actual dividing value D. E represents the precision of the balance, and D represents the readability of the balance.
The specific meaning of the two dividing values:
1.d is the minimum scale of the balance, called the dividing value, and can also be called the minimum reading precision. According to the standard, it is called the scale of the scale, which is represented by the symbol "d".
2.e is the scale dividing value of the balance of the balance, that is, the dividing value used for the timing. The grading value used in the verification is different from that of the balance of the actual scale of the balance D. It is not the same as the value of the D, but the value that needs to be changed according to the human regulation. E=5d can be specified, or e=10d or e=2d can be established, as long as it does not violate the provisions of the national metrological verification regulation.
The electronic scale D is the minimum accuracy of the electronic balance, and the calibration scale e is used to check the technical index when the electronic balance is calibrated. To be accurate, the best accuracy of the electronic balance is not only to look at the D value, but also to the E value. In particular, the Department of precision weighing, scientific experiment and the transfer of quantity value, such as the precision electronic balance, such as 0.01mg balance, is best to look at the calibrating scale e.
