  DO Calibration

Calibration is necessary for accurate dissolved oxygen measurement. Two DO calibration 

modes are available in PD meter for calibration,

  Saturated oxygen concentration mode (%)
  Dissolved oxygen measurement mode (mg/L)

To perform various DO calibrations, follow the procedures detailed below:

Set the air pressure value (default setup is 101.3 kPa) before calibration for accurate 
measurement.

  Calibration in saturated oxygen concentration mode (%)

 Prerequisites

  Clean the membrane at the tip of the DO electrode with DI (deionized) water and wipe it 

with tissue paper.

  Switch on the PD meter and plug in the DO electrode.

  Press the 

 key to keep the PD meter in saturated oxygen concentration mode (%) 

mode.

  Calibration performed in clean air is referred as air calibration.
  Perform the air calibration in clean air at a location not subjected to dramatic temperature 

change, rain or direct wind.

  Do not hold the tip of DO electrode with hand during calibration, as the electrode may be 

affected by temperature causing instability in calibration value.

To abort an ongoing calibration process at any point of time, press the 

key.
