Electrical Connection of Mass Flow Meter

>Display Menu

The 4-way button with center push gives access to a user-friendly menu, e.g. for zero function, for selection of pre-installed gases in pre-installed ranges, setting of engineering units, alarm functions (minimum/maximum/counter limit) and counter functions. Password protection is provided to prevent unauthorizes changes.
