4210 Flow Meter
Section 2 Programming
Isco ships the flow meter with a program already installed called
the default program. You can use this program as an example to
see the flow meter's capabilities. Note that the default program is
just to test the unit at the factory. The flow meter's internal com-
puter must always have something programmed into the unit, so
that becomes the default program. Your flow situation will
usually require other programming choices. The text provided
with each screen explains the reasons for the various menu
options.
2.1 Display The display is a two-line, forty character-per-line liquid crystal
(LCD). It has a backlight feature for easy viewing in low light sit-
uations. The display has three different operating modes:
normal, programming, and messages. In the normal mode, the
display shows such things as level, flow rate, total flow,
parameter measurement, etc. In the programming mode, the top
line of the display shows each step as you work through the
program while the bottom line shows the choices available for
that step. In the message mode, the display provides instruc-
tional information, such as how to leave programming, or what to
do if you have entered a number that is out-of-range. Following is
a “normal” display on the flow meter. This is typical of what the
flow meter will display when it is in the normal operating mode
and you are not programming it.
An interpretation of the numbers on this display would be as
follows: Time and date will be replaced by pH/D.O. and temper-
ature if you are using parameter sensing. The (X X) to the right
of the time indicates letters that may appear from time to time
on the 4210 Flow Meter.
The letter C will appear when the flow meter is communicating
with a remote computer (FLOWLINK applications only). The
letters E or D will appear (Enable or Disable) when the sampler
enable function (step 6) is programmed by condition. (Pro-
grammed by condition means that the flow meter will enable the
sampler only when a certain condition or set of conditions,
sensed by the flow meter, are met.)
