YSI 610DM - Manual (Page 28)

YSI Incorporated Displays and Loggers 26
list, or offered right after you select a sensor. Select the sensor and number of points you
wish and press Enter.
The YSI 610 requests the exact value to
calibrate, and commands the sonde to
calibrate.
The YSI 610 will step you through multi-
point calibrations if applicable.
All YSI sondes described in this manual
display the reading until you are satisfied
that it is stable.
Errors can occur during calibration. The
number you enter may be out of range, the
sensor may be installed incorrectly or the
sensor may be drifting. If an error occurs,
the sonde rejects the calibration and an
error message is displayed on the YSI 610
screen. Some types of errors can be overridden and the display then offers you an option
to accept. Never override an error or warning message without understanding the
problem and being certain that your data will not be compromised.
When calibrating turbidity or chlorophyll, it is important to eliminate bubbles that can
drastically alter results. The 6026 Turbidity Probe and the 6025 Chlorophyll Probe have a
wiper that is very helpful in removing bubbles during calibration and reading. You can
activate the wiper manually by pressing the T key, at any time while you wait for
stabilization.
Before a calibration is complete, you may press Esc to abort it.
7.5 SETUP PARAMETERS AND SETUP SENSORS
These two menu choices allow you to display or change the active sensors and
parameters in the sonde. They are entered through the YSI 610 Main menu or through the
Deploy menu into Sensors (Setup Sensors) and Report (Setup Parameters). See Section
2.9, Sonde Menu of the YSI 6-Series Operations Manual.
7.6 DEPLOY MODE
The Deploy menu takes you right into the Run /Unattended menu of the sonde. For more
see Section 2.9, Sonde Menu of the YSI 6-Series Operations Manual.
