The correctness of the electronic analytical balance is the correctness of the indication of the electronic balance. It indicates the ability of the balance to be close to the true value. From the perspective of error, the correctness of the balance is the degree of systematic error reflecting the indication of the balance. .

    The stability of an electronic analytical balance is the ability of an electronic analytical balance to automatically return to its original equilibrium position after it has been disturbed. For an electronic balance, the equilibrium position is always expressed by an analog indication or a numerical indication. Therefore, once an instantaneous disturbance is applied to the electronic balance, although the indication changes, when the interference is removed, The electronic balance can be restored to its original value, and we call the electronic balance stable. For an electronic balance, the stability of the balance is the primary criterion for the balance to be used. Electronic balances without balance stability cannot be used. Second, the sensitivity of the electronic balance:

    The sensitivity of an electronic analytical balance is the ability of an electronic analytical balance to perceive the amount of change in the mass of an object placed on a day balance disc. The sensitivity of an electronic balance can be expressed by angular sensitivity, or line sensitivity, or indexing sensitivity, or digital (indexing) sensitivity. For electronic balances, it is mainly expressed by indexing sensitivity, or digital sensitivity. The smaller the amount of quality change that the balance can detect, the more sensitive the balance is. It is obvious that for electronic balances, the sensitivity of the balance is still one of the important performances for judging the balance.

    The invariance of the flattened value of the electronic day analysis refers to the degree of agreement of the obtained measurement results by measuring the same object multiple times under the same conditions of the electronic balance. For electronic balances, there is still the invariance of the balance of the balance, such as the repeatability of the electronic balance, the control of reproducibility, the control of the zero balance of the electronic balance and the error of the zero return. When the electronic balance is unloaded or loaded, the electronic balance is regulated. Control of the indication drift of time.

    For a lever balance, the correctness of the balance is mainly reflected in the correctness of the balance arm ratio. However, whether it is a mechanical balance or an electronic balance, the correctness is also reflected in the correctness of the analog scale or digital scale of the balance, and the correctness of the indication due to the placement of the load on each point on the balance meter.
