4.3 CC Offset Routine

The parameter CC offset cannot be written to. This parameter can only be changed by the gauge using the CC offset routine cmd. (CC_OFFSET 0x000A, CC_OFFSET_SAVE 0x000B) In BQstudio, it can temporarily appear that this parameter has successfully been written to. However, after a read all is performed, see the value return to the previous value.
