be flashing. The flashing indicates that this choice is the current
one held in memory. If you are satisfied with this choice, just
press Enter, and the flow meter will advance to the next step.
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 is over the last selection.
From time to time you will notice an arrow that points to the
right edge of the display. This indicates additional choices are
available beyond what you can see on the display. By continuing
to press the right arrow key, you can view these unseen 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 are 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, press Enter. The display
will then automatically advance to the next step of the program.
All of the program steps contain several substeps that must be
completed before you advance to the next program step. Some
steps, like Reset Totalizer contain only a few substeps. Some
steps will require the entry of a numeric value.
Program these steps by using the number and decimal keys to
enter the correct value.
You can program most of the flow meter in the shop, rather than
at the job site, with the exception of step 3, Adjust Level/Param-
eters. To set level, you must make an accurate measurement 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 begin by pressing Enter, and start with step 1. If
the flow meter has been in use and you only need to change the
program, you would be more likely to use the Go To Program
Step key. With this key, you can go directly to the program step
you need to change, instead of having to step through every
single screen.
If you change an entry and want to change it again, 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 continue 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 com-
pletely change before you exit 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
