4.4.8 Maximum flow entry Screen display Flo @ max
Factory default value 1.000
This selection is offered only if the user has chosen a duty of Flow which requires entry of the maximum
flow capability of the chosen structure (not the maximum flow expected in the application), or is shown
when manually navigating the main menu - ignore if duty chosen is Level, Distance or Contents.
To enter the value for maximum flow:
a) Press the blue button → to enter the “Flo @ max” menu and press the blue button → again to allow
editing.
The leading digit of the maximum flow will now be flashing, indicating it may be changed.
b) Use the green button ↓ to edit the value of the leading digit.
Once correct, use the blue button → to select the next digit and then the green button ↓ to edit as
before, or the blue button → to move to the next digit. Continue this sequence until all 5 digits are
correct.
c) Press the blue button → a final time to confirm the new value. None of the digits should now be
flashing.
d) If the new maximum flow value is incorrect, the edit sequence for the maximum flow can be re-started
by pressing the blue button → again.
e) If the maximum flow value entered is correct, press the red button ↵ to save the value to memory and
automatically scroll on to the next main menu option: “4”.
However, with a duty of Flow chosen if the data already entered allows the MSP400 to calculate the
maximum flow, the 4mA and 20mA points are automatically set to 4mA at 0 flow and 20mA at
maximum flow.
The next menu item offered in this case is “d”.
Refer to section 4.4.12.
