273		-Notes:
274		-Always use the sensor with the most trusted reading as the reference (do not modify its K-value).
275		-The default K-value 03E8 (1000) implies no scaling. Values below 03E8 reduce the output; values above increase it.
276		-CRC is auto-generated by the tool (no manual calculation needed).
