The absolute oxygen level, µM, is a default parameter and cannot be disabled, refer TD262a.
To enable/disable a parameter:
Select the output parameter from the list, press
setting by clicking the box (box is now checked), press
We recommend that you enable all parameters in case of later use. The memory card storage capacity is
normally not a limitation for the SEAGUARD
coefficients and perform quality control on the data.

3.2 RedReference, Calibration Coefficients and Salinity Compensation

Special property settings and calibration coefficients are found in User Maintenance.
Open the User Maintenance
and tap Configure in the lower part of the window. The user maintenance holds four submenus:
• Node Description

• Calibration Coefficients
• Enable RedReference

of vapour pressure in the calculations of the output
parameters. Enable HumidityComp can be set to No if
measurements are performed in dry air conditions or if you
like to perform the humidity compensation as a post-
processing operation. Disabling this will typically lead to 1-3
% lower readings depending on the relative humidity of the
air.
