4230 Flow Meter
Section 2 Programming
2-30
Note
The flow meter cannot communicate at 600 baud. If your
sonde has been set up for 600 baud, you will get a communi-
cations failure. Consult the YSI 600 Manual for what to do in
this case.
If the communications check is good, the following display will
appear:
After you press Enter, the flow meter will advance to the fol-
lowing display:
• Selection of NOT MEASURED for any of the YSI menus
will prevent you from activating those functions later in
the program.
If you want the YSI 600 to measure pH, select pH. If you do not,
select NOT MEASURED.
If you want the YSI 600 to measure D.O., select MG/L. Oth-
erwise, select NOT MEASURED.
For any of the YSI CONDUCTIVITY options, if you press Enter,
the following display will appear:.
This value is provided because conductivity rises (~2%/ °C) with
temperature. The default setting is 1.91%. This value is the tem-
perature coefficient for pure KCl (potassium chloride) in water.
For other salts this value will be somewhat inaccurate, but it
does provide a close approximation for solutions of many common
salts, such as NaCl (sodium chloride), NH
4
Cl (ammonium
chloride) and sea water. If you use the value of 1.91, in most
cases you will be able to identify that gross changes are occurring
in the ionic content of the stream. If you move with the right
arrow, the following options will appear on the display
