5-4 Calibrating Your Module
For example, based on the table below, command 4 0 0 asks for zeroing the
min and max coefficients of channel 0. All results are complete with this one
command.
Once the slave completes the calibration command, the module echoes back
the command and data in the MODULE response word, see the General
MODULE Response Word below. The controller is informed the calibration
sequence is complete.
