Electronic balance calibration method of easy operation

Abstract

The invention discloses an electronic balance calibration method of easy operation. The electronic balance calibration method comprises the following steps that 1) an electronic balance is arranged on a horizontal desktop; and then the four supporting legs of the electronic balance are adjusted so that the level bubble on the electronic balance is enabled to be positioned in the middle exactly. The electronic balance is wiped so that the medicine bottle residues adhered on the balance can be erased and the influence of the tablet residues on the accuracy of the electronic balance can be avoided; corrosion of the medicine residues to the electronic balance can also be avoided; meanwhile, comparison with the value of the electronic balance is performed through deionized water so that the error of the electronic balance can be accurately judged; the electronic balance can be greatly calibrated; and the weight of the deionized water is repeatedly weighed in the calibration process so that the weighing value of the electronic balance can be more accurately obtained, deviation of the reading value of the electronic balance caused by misoperation in the operation process can be avoided and further accurate calibration can be performed.

Description

technical field [0001] The invention belongs to the technical field of precision electronic instruments, and in particular relates to an electronic balance calibration method with simple operation. Background technique [0002] Electronic balance is a commonly used experimental instrument in chemical laboratories. Because of its high accuracy, it can measure the quality of medicines to an accuracy of one ten-thousandth; therefore, it can effectively improve the success of the experiment during the experiment. rate; when calibrating the electronic balance, just use the electronic balance to measure once, it is easy to have a large deviation in the measured value, resulting in calibration failure. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides an electronic balance calibration method with no deviation in reading and simple operation. [0004] In order to achieve the above object, the present invention adopts...
