12
the D-Opto Logger is installed at a field site at 435 meters above sea level,
and a fully aerated reference solution is prepared on site, the actual
dissolved oxygen percent saturation is calculated at 95%.
Procedure:
1) Place the D-Opto Logger is placed in the reference solution, and
allow it to equilibrate for at least 30 minutes.
2) Power up the D-Opto Logger and start D-OptoLog. Once the
measurements have stabilised, press the “Calibrate” button in the
main window to open the Calibration window.
3) Enter the pressure corrected dissolved oxygen percent saturation
of the reference solution in the gain calibration edit box and press
the “Reset gain” button.
4) The D-Opto performs a calibration routine followed by a self check;
this can take up to 30 seconds. Do not remove the D-Opto Logger
from the reference solution during this period. The operator will be
notified when the process is complete.
