Electronic Balance

Four performance indexes of electronic balance: Aura life everyone in the use of electronic balance, the first consideration is the stability of the balance, the balance ofagility, balance is correct and balance shows the value of invariance. The so-calledstability refers to the stability and accuracy of balance; sensitivity refers to the speed of response to balance reading, in this regard electronic balance is mechanical balancehas higher sensitivity; validity refers to the accuracy of the reading; and invariancerefers to stable balance of reading, namely the balance reading floating range, the smaller the floating range to illustrate the invariance of the better.

Invariance, showing the value of an electronic balance:

Electronic balance shows the value of invariance, refers to the balance in the same condition, the determination of the same object several times, the degree of consistencydetermination results. For the electronic balance, still have invariance balance shown value, such as the repetition of electronic balance, the reproducibility of the control,control of the electronic balance to zero and zero error of electronic balance, electronic balance load or load time, showing the value of drift control in electronic balance set time.

Two the correctness, electronic balance:

The correctness of electronic balance, is the right balance indication, it said the balanceshown value capacity close to the true value; the errors from the point of view, the validity of scale, is to reflect the balance shown value error degree of the system.

The sensitivity of electronic balance is the balance, can detect on the day the ability to change the amount of balance disk of the object mass. The sensitivity of electronic balance, can through the angular sensitivity, or line sensitivity, or indexing the sensitivity, or digital (indexing) sensitivity to represent. For the electronic balance,mainly through the index sensitivity, or digital sensitivity to represent. Mass balance canperceive the change quantity is small, then the balance more sensitive, visible forelectronic balance, the balance is still one of the most important performance criterionof sensitivity of balance quality.

Four, the stability of electronic balance:

Stability of electronic balance, is refers to in the balance is disturbed, the ability to automatically return to the initial position of the balance of their. For the electronic balance, the balance position is always passed so indicating analogue or digitalindication value to performance, once the interference of electronic balance, apply some transient, although showing the value of change, but the disturbance was eliminated, balance and can revert to the original indication, we call the electronic balance is stable the. An electronic balance, the balance is the primary determinant of stability conditions of balance can be used, do not have the balance stability ofelectronic balance cannot use.
