Claim 3:
4. The weighing method of claim 3, wherein the step of electronically commanding the self-calibration weighing module to load the material tank with the predetermined calibration weight and displaying the loaded weight data comprises the substeps of:
using the automatic loading device to perform a loading action after receiving the electronic command;
after loading, using the meter or the PLC control system for displaying the loaded weight data; and
comparing the loaded weight data with a known mass of loaded weights added by the loading action for the self-calibration weighing module to obtain a weight deviation value, wherein the predetermined requirement comprises an acceptable deviation value range or threshold, and wherein the mass of loaded weights is the predetermined calibration weight.
