Select the language appropriate for your application. The menus
and the printed reports will appear in the selected language.
Press Enter. The SETUP menu will reappear. This time select
PROGRAM LOCK from the menu. Press Enter:
PROGRAM LOCK keeps the program from being changed. Select
OFF while you are programming, and then go back and select
ON if you ne ed to lock the pr ogram. At that, we suggest using the
lock only if there are compelling security reasons.
Further changes will require entry of the password, which is the
model number of the flow meter: 4220. If you select ON, there is
a time-out before the lock engages.
If you continue to work through the rest of the program, the lock
will not engage until you are done. But if you stop programming
longer than two minutes, the lock will engage, and you will not be
able to make any further program changes.
Press Enter and the SETUP menu will reappear.
2.4.3 Step 1 - Program
PROGRAM will flash. (Note that PROGRAM is always the
default choice. That is because you are more likely to need to
make changes in the PROGRAM section of the software than in
the SETUP section.)
Note
If you choose NOT MEASURED for any selection, the flow
meter will make no further reference to that function for the rest
of the program, and you will be unable to activate that function
later. If there is a feature you need that does not appear when
the manual says it should, return to step 1 and make sure you
have not accidentally left it turned off.
If you program a parameter value as a condition for sampler
enabling, pacing, dialout, etc., and then turn that parameter
sensor off, the flow meter will also remove that condition from
the program.
Consider all aspects of your program before you make any
changes!
Press Enter. The following will appear:
Selection of feet, inches, meters or mm depends on your situ-
ation. You would select NOT MEASURED if you were using the
flow meter for some other form of sensing only, such as pH, or
