Returning to step 3, Parameter to adjust, the following display
will appear:
Note
If you are using the YSI Sonde and YSI 600 does not appear
on your display, return to step 1, Program, and make sure you
have selected YES from the YSI CONNECTED menu.
If you select YSI 600, the following display will appear:
If you select pH for the parameter to calibrate, the following
display will appear:
You can perform a two- or three-point calibration for pH with the
YSI sonde. The menus that follow are similar to those in the pre-
ceding section for the Isco pH sensor. Select the calibration that
best suits your stream’s profile. When you complete the pH cali-
bration successfully, the following display will appear:
Returning to the YSI menu, if you select D.O:
ALTITUDE is just off screen to the right. Programming for YSI
600 D.O. is essentially the same as that described for the Isco
D.O. sensor on the preceding section, with the exception that you
always place the sensor in a cup, rather than wrap a moist cloth
around it as is done for the Isco D.O. sensor.
If you select CONDUCTIVITY for the parameter to calibrate, the
following display will appear:
MS/CM is millisiemens per centimeter. The siemen is the S.I.
(Système Internationale) name for the unit of conductance,
which is also the reciprocal of the ohm. The siemen was formerly
