Max Error Time Cycle
Equivalent
U1 1 255 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.

Gauging
Max Error Cycle Delta U1 0 255 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.
