full-scale value of four feet. If the actual level reading is cur-
rently two feet, the analog output would read 12 mA (50% if the
4-20mA current range is selected) or 10 mA (50% if the 0-20 mA
current range is selected).
The flow meter will then request that you repeat the process of
defining the data type and setting the minimum and maximum
values for any of the other analog ports you activated previously
in Setup.
2.8 Step 3 - Parameter to
Adjust
This step lets you enter the measured level in the flow stream. It
also lets you calibrate the pH (acidity or alkalinity), D.O. (dis-
solved oxygen) parameter sensors, and the YSI 600 Multiple
Parameter Sonde. There is no calibration step for the temper-
ature sensor because it does not need calibration. When you
select step 3 the following will appear:
LEVEL will not show up if you are using the flow meter only for
parameter sensing. Likewise, pH and/or D. O. and YSI 600 will
not show up on the display if you have locked them out by pro-
gramming selections you made in step 1.
Remember that selection of either pH or D. O. in step 1 will keep
the other from appearing on the display in this or subsequent
programming steps. If the parameter you want does not appear
in this menu, exit the program and return to Setup. Check to see
that you have not accidentally locked your choice out with selec-
tions you made in the early section of the program.
If you select NONE, the flow meter will advance to the next step.
If you select LEVEL, the following will appear:
First, measure the level in the flow stream. This is usually done
with a measuring stick, or you read the level from a scale that
may be painted or printed on the side of the primary measuring
device.
