QUICK Do CALIBRATIoN
Perform this calibration procedure when Quick Do Calibration is enabled in
the System Setup menu.
Ensure the Do sensor has a good membrane with electrolyte installed.
1.
A good membrane is free of wrinkles, tears, fouling and air bubbles.
Install the sensor guard onto the probe.
Moisten the sponge in the grey calibration/storage sleeve with a small
2.
amount of clean water and install it over the sensor guard. The sponge
should only be moistened and the calibration/storage sleeve should not
have excess water in it that could cause water droplets to get on the
membrane. The storage sleeve ensures venting to the atmosphere.
Power the instrument on and, if using a Polarographic sensor, wait
3.
approximately 5 to 15 minutes for the storage chamber to become
completely saturated and for the sensor to stabilize. If using a Galvanic
sensor, wait approximately 5 to 10 minutes for the chamber to become
completely saturated. Auto Shutoff should be disabled or set to at least
20 minutes. See System Setup menu for more information on adjusting
the Auto Shutoff.
Ensure the barometer is reading accurately. If necessary, perform a
4.
barometer calibration.
Press and hold the Calibrate key for 3 seconds. Using the up or down
5.
arrow key, highlight Dissolved oxygen and press enter. The Pro2030
will indicate ‘Calibrating %Do’ on the display. The instrument will
automatically calibrate the sensor to the current barometric pressure. If
Do Local% is enabled, the sensor will calibrate to 100%. This may take
up to 2 minutes depending on the age of the sensor and membrane.
You can press the Cal key at this time to cancel the calibration.
‘Calibration Successful’ will display for a few seconds to indicate a
6.
successful calibration and then the instrument will return to the Run
screen.
If the calibration is unsuccessful, an error message will display on the
7.
screen. Press the Cal key to exit the error message and return to the Run
screen. See the Troubleshooting guide for possible solutions.
It is not necessary to calibrate in both % and mg/L or ppm. Calibrating
in % will simultaneously calibrate mg/L and ppm and vice versa. YSI
recommends calibrating the dissolved oxygen sensor in % for both ease
and accuracy.

CALIBRATING IN PERCENT (Do%)
Perform this calibration procedure when Quick Do Cal is disabled in the System
Setup menu.
Perform steps 1-4 of the Quick Do Calibration procedure.
1.
Press and hold the Calibrate key for 3 seconds. Highlight Dissolved
2.
oxygen and press enter. Next, highlight % and press enter.
The Pro2030 will display the current Do% and temperature readings
3.
along with the % calibration value. The % calibration value is based on
the barometer reading.
Wait at least 3 seconds, then, once the Do% and temperature readings
4.
are stable, press enter to complete the calibration. or, press the Cal key
to cancel the calibration.
‘Calibration Successful’ will display for a few seconds to indicate a
5.
successful calibration and then the instrument will return to the Run
screen.
If the calibration is unsuccessful, an error message will display on the
6.
screen. Press the Cal key to exit the calibration error message and
return to the Run screen. See the Troubleshooting guide for possible
solutions.
CALIBRATING IN PERCENT (Do LoCAL% ENABLED)
Perform this calibration procedure when Do Local% is enabled in the System
Setup menu.
Perform steps 1-4 of the Quick Do Calibration procedure.
1.
Press and hold the Cal key for 3 seconds. Highlight Dissolved oxygen
2.
and press enter.
%Local will automatically be highlighted, press enter. The Pro2030 will
3.
display the current Do% and temperature readings along with the %
calibration value. The % calibration value will always be 100% for Do
Local%.
Wait at least 3 seconds, then, once the Do% and temperature readings
4.
stabilize, press enter to complete the calibration. or, press the Cal key
to cancel the calibration.
‘Calibration Successful’ will display for a few seconds to indicate a
5.
successful calibration and then the instrument will return to the Run
screen.
If the calibration is unsuccessful, an error message will display on the
6.
screen. Press the Cal key to exit the calibration error message and
return to the Run screen. See the Troubleshooting guide for possible
solutions.
