Step: Units
Note
Local units set immediately by wizard
All local units are set immediately in wizard when "Units" step completed.
•
Units are an exception to the general rule for all other wizard settings: Settings for quick
commissioning wizard are inter-related and changes apply only after "Apply?" is set to
"Yes" in final step.
•
Units for local operation are applied even if wizard is cancelled in final step. Therefore, re-
run the wizard if a change must be made to units setting.
