Manual Dissolved Oxygen Calibrationmethod can be used to calibrate the DO probe to the value achieved by a Winkler titration. A manual calibrationinvolves performing a Winkler titration and using that sample as a calibration standard. The oxygen level resultfrom the titration is entered in a manual calibration as the dissolved oxygen value. This correlates the meter inputto 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. f1 (cal) orto highlight DO/RDO – Channel and press f2 (select).2.
