Manual Dissolved Oxygen Calibration
A manual calibration is performed using a water sample with a known concentration of dissolved oxygen. This
method can be used to calibrate the DO probe to the value achieved by a Winkler titration. A manual calibration
involves performing a Winkler titration and using that sample as a calibration standard. The oxygen level result
from the titration is entered in a manual calibration as the dissolved oxygen value. This correlates the meter input
to the Winkler titration. This method is inherently less accurate, due to the possibility of titration errors.
Note: In most calibration screens, press f1 (esc) to return to the measurement mode without saving the calibration.
