Default Unit Description
255 12 2h After valid QMax update, each passed time period of
Time Cycle Equivalent will increment of MaxError() by
Cycle Delta. Time Cycle Equivalent increments Max
Error by 0.05% for every Time Cycle Equivalent time
period following the last QMax update.
255 5 0.01% Each increment of CycleCount() after valid QMax
update will increment of MaxError() by Cycle Delta.
Setting this parameter to 0 disables the MaxError
increment by time or cycle increment.

Description
Averaged cell resistance at Reference Grid point.
Automatically updated when Update Status is set
to 0x6 by the gauge. To automatically update
again, set Update Status to 0x4 or manually set
when Update Status is set to 0x6.
