Description
Technical field
The invention belongs to instrument calibration technical field, more particularly, to a kind of electronic scale calibration method.
Background technology
Electronic scale is a kind of intelligent measured body weight instrument, has the advantages of measurement accuracy is high, reading facilitates, but
When long-time is not used, there can be certain error during electronic scale, must be to electron when this allows for reusing
Weight scale is calibrated, but current calibration method is more complicated.
The content of the invention
The present invention is for overcome the deficiencies in the prior art, there is provided a kind of electronic scale calibration method simple to operate.
To achieve these goals, the present invention uses following technical scheme：A kind of electronic scale calibration method, including with
Lower step:
(1) electronic scale is placed on a levelling bench, platform surface and electronics is cleaned with cotton when putting
The bottom surface of scale；
(2) surface of electronic scale is cleaned with cotton, then opens the switch of electronic scale；
(3) graduated cylinder is taken, and the distilled water of certain volume is measured with graduated cylinder；
(4) graduated cylinder equipped with distilled water is lain in a horizontal plane in into electronic scale surface；
(5) numerical value shown on electronic scale is read；
(6) volume of distilled water in graduated cylinder is read, and calculates the quality of distilled water；
(7) the quality summation of distilled water and graduated cylinder is calculated, and is contrasted with the display numerical value on electronic scale；
(8) error of indication is obtained.
The surface of electronic scale is first cleaned with cotton, avoids and has influence on measured value because remained on surface has debris
The accuracy of accuracy, further lifting test, electronic scale is placed on levelling bench, and clean platform with cotton
Surface and the bottom surface of electronic scale so that electronic scale is put more horizontal, the measured value further lifted it is accurate
Degree, measures the distilled water of certain volume with graduated cylinder, and graduated cylinder quality is, it is known that because the density for cooking water is standard value, therefore can root
The quality of distilled water is directly calculated according to the volumetric quantities read in graduated cylinder, then by the gross mass and electronics of graduated cylinder and distilled water
The numerical value shown on scale is contrasted, so that it may is obtained the error of indication of electronic scale, and then is calibrated electronic boby weight
The purpose of scale, calibration method of the invention is simple to operate, easily implements.
Further, when reading distilled water volume in graduated cylinder in the step (6), keep sight and liquid level least significant end neat
It is flat；Realization flushes with liquid level least significant end so that the volumetric quantities of reading are more accurate, further reduce measurement error.
In summary, the graduated cylinder quality of distilled water equipped with certain volume of the invention of being weighed by using electronic scale, and
The actual mass for showing numerical value and graduated cylinder is contrasted, the error of indication is obtained and then calibrates the effect of electronic scale,
The calibration method of the present invention is simple, easily implements.
