Note that the items for setting differ depending on the reference materials used for calibration. 
 

 

 

 

Item 

Description 

Air saturated water 

This calibration uses air-bubbled water as the reference. Enter 
[Atmospheric Pressure] at the time of calibration. 

RMDO (Reference Material DO) 

(Under development) 

A  reference material can be used for calibration, which is 
under development as of May  2016.  Enter the values 
displayed on the label of the reference material into the 
[RMDO] and [Salinity].
