High-precision electronic balance calibration method

Abstract

The invention discloses a high-precision electronic balance calibration method. The method comprises the steps of cleaning an electronic balance, leveling the electronic balance, preheating the electronic balance, calibrating the electronic balance, verifying the electronic balance, and recalibrating the electronic balance. During calibration, a calibration key is pressed, so that a calibration mode is enabled; the weights of standard weight needing to be verified are sequentially input; after zero clearing is performed, the standard weights are sequentially taken; a glass door is closed for weighing; the electronic balance automatically records a numerical value after data is stable; the numerical value is calibrated to a set numerical value; the calibration key is pressed down after all weighing is completed, and at the moment, the electronic balance automatically marks the numerical value recorded each time in a vertical coordinate system; a curve is fitted, a new measurement curve is generated; and the position of a zero point is recorded, and calibration is completed.

Description

technical field [0001] The invention relates to the technical field of electronic balance calibration methods, in particular to a high-precision electronic balance calibration method. 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. Therefore, the present invention provides a high-precision electronic balance calibration method to solve the problems raised in the above-mentioned background technology. Contents of the invention [0003] The purpose of the present invention is to provide a high-precision electronic balance c...
