Special parameters

All parameters described in this chapter affect the behavior of the IQ

FLOW®. Please be aware that wrong settings can

disorder the output. To avoid unintentional changes, some parameters are locked (shown by the



symbol). To unlock

parameters set parameter 'Init Reset' to 'Unlocked'.
