• The return value is unsigned 1-byte wide, the unit is 1, the resolution is 0.005, and the practical range is from 0.000 to 1.000. Value 0xEE (i.e. 1.190) specifies a sensor error. Other values are undefined.
• FRC 1-byte: FRC return value is the return value (with 0.005 resolution) +4 (i.e. 4 is 0.000, 204 is 1.000).
