People with the electromagnetic force balance is called an object called gravitational balance electronic balance. It is characterized by accurate and reliable weighing, fast and clear display, automatic detection system , simple automatic calibration device and overload protection.
The electronic analytical balance is first installed, moved, and the temperature of the laboratory changes significantly. Calibration is required to ensure that the electronic balance is adapted to the local gravitational acceleration and environment. The standard weight is used to calibrate the electronic balance. Many customers will ask about the difference between an electronic balance inner school and an external school. The following is a brief introduction.
The electronic balance of the internal model refers to the calibration of the weight inside the electronic balance. The electronic balance with the built-in weight lifting device is driven by the motor. The calibration process can be completed by pressing the calibration button during calibration.
The electronic balance of the external school model refers to the calibration process by manually pressing the calibration button and then placing the standard weight on the electronic balance pan. The weights are saved in a separate weight box.
The accuracy of the electronic balance has nothing to do with the internal school and the external school. It mainly depends on the grade of the weight and the quality of the electronic balance sensor. Generally, the outer weight and the built-in weight level of the new factory balance are the same, so there is no difference. However, with the passage of time, the loss of the outer weight is generally larger than the built-in weight: it will be affected by dust, acid and alkali corrosion, etc. A finger print will have a weight of tens of micrograms, and if it is improperly stored, it will be lost. The situation exists. Therefore, if the annual measurement test is unqualified, the weight needs to be replaced.
The balance of the built-in weight generally does not appear in the above situation, and the deviation can be corrected by modifying the calibration program parameters of the balance. Although the inner school balance is about 20% more expensive than the external school, it is easy to use, so it has obvious advantages in use. .
