ALTITUDE
ALTITUDE = X.XX FT (or meters)
Enter the altitude for your location. Then:
WRAP D. O. PROBE IN MOIST CLOTH
PRESS ENTER WHEN STABLE: X.XXX MG/L
For more detailed information on the pH and D. O. probes, see
Section 4.
Returning to step 3, Parameter to Adjust, the following display
will appear:
PARAMETER TO ADJUST
• NONE • • (LEVEL) • • (pH) • • (DO) • • (YSI 600) •
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 will appear:
YSI 600 PARAMETER TO CALIBRATE
• NONE • • pH • • DO • • CONDUCTIVITY •
If you select pH for the parameter to calibrate, the following
display will appear:
YSI 600 pH CALIBRATION
• pH 4 & 7 • • pH 7 & 10 • • pH 4, 7, & 10 •
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:
CALIBRATING...
PRESS ENTER TO CONTINUE
Returning to the YSI menu, if you select D.O:.
YSI 600 DISSOLVED OXYGEN CALIBRATION

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.
