Abstract

The weighing calibration goes with the acquisition of input signal In and corresponding inner code RCn, RCm+n of the Im+n, index number A, baseline parameter Is and experience coefficient beta , determining the instrument rectification coefficient alpha , output Wi corresponding to the instrument input signal, PC connected to the data cable, weight and any instrument respectively stored with empty Wio and calibrated Wit and serial number s, capacity C, index number R or G of each weight to establish the weight parameter data base, with the PC inquiring of the corresponding data based on the serial number of each weight, downloading the parameter to any instrument and decide its calibrated measuring range Fs to finish the calibration process.

Description

technical field [0001] The invention relates to a calibration method of a weighing device. Background technique [0002] Every weighing device needs to be calibrated, and the calibration process of the weighing device is the process in which the display output value of the instrument and the corresponding weight value correspond to the scale body. The calibration method of the traditional weighing device is to connect an instrument to a scale body via a data cable on the client side, and then carry out the calibration according to the internal code of the empty weighing pan and full weighing, as well as the capacity and division number / division value of the scale body. calibration. However, with the continuous increase of product models and types, setting calibration for different types of weighing means to carry out factory calibration and user calibration for a corresponding number of instruments and a corresponding number of different scales. Not only is installation and...
