4220 Flow Meter
Section 2 Programming
2-4
If you want a different choice from the one that is flashing, you
can move across the display by using the left and right arrow
keys. Each time you press the right arrow key, the flashing
selection will move one position to the right. This will continue
until the flashing cursor is over the last display.
You may notice an arrow pointing to the edge of the display. This
indicates additional choices are available beyond what you can
see. By continuing to press the right arrow key you can view
these unseen menu options. After reaching the furthest option,
the arrow will move to the left side of the display, indicating that
there are options unseen to the left. These will be the options you
started with. If you want to go back to one of them, use the left
arrow key until the option you need reappears. When the
desired selection is flashing, just press Enter. The display will
then automatically advance to the next step of the program.
All of the program steps contain “substeps” that must be com-
pleted before you advance to the next step. Some steps, like
Reset Totalizer contain only a few substeps. Some steps require
the entry of a numeric value. Program these steps by using the
number and decimal keys to enter the value.
Note that it is possible to program the flow meter in the shop,
rather than at the job site, with the exception of step 3, Adjust
Level/Parameters. To set level you must make an accurate mea-
surement of the level in the flow stream and then enter that
value. This can only be done at the job site.
If you are programming the flow meter for the first time, gen-
erally you will press Enter, start with step 1, and go on from
there. If the flow meter has been in use and you need to change
only certain aspects of the program, you would more likely use
the Go To Program Step key. With this key you can go directly
to the program step you need to change, which saves time.
If you change an entry and do not like it you can make the
display revert to the original entry by pressing Clear Entry. If
you have already pressed Enter, however, the new value will be
in memory. To change it, press Exit Program. If you are in the
middle of a program step with multiple substeps, the flow meter
will display, “Changes have been made in step; press 0 to con-
tinue or 1 to discard.” If you press 1, the display will return to
normal and the last step you were working on will revert to its
previous selection. (Any program step you completely change
before exiting will remain changed.)
You can re-enter the program with either Enter or the Go To
Program Step keys. If you become confused while pro-
gramming, the best suggestion is to press Exit Program and
start over. Also remember that you can have the flow meter print
a complete list of your program choices by exiting the program
and by pressing the Print Program key as soon as the display
returns to the normal operating condition, displaying level and
total flow, etc.
