426 426  
427 427  1. Zero calibration. Don't put anything on load cell and run **AT+WEIGRE** to calibrate to Zero gram.
428 428  1. Adjust calibration factor (default value 400): Put a known weight thing on load cell and run **AT+WEIGAP** to adjust the Calibration Factor.
429 429  1. (((
430 -Weight has 4 bytes, the unit is g.
410 +Remove the limit of plus or minus 5Kg in mode 5, and expand from 2 bytes to 4 bytes, the unit is g.(Since v1.8.0)
