On this screen you can adjust the DO: setting between %Sat and mg/L. This
will set the Meter to display Dissolved Oxygen as either % Saturation or in
milligrams/Litre (which is the same as parts per million). Both readings are
automatically corrected for atmospheric pressure, sample temperature and
sample salinity.
The second option on this screen allows you to choose how the Meter displays
Electrical Conductivity. There are four options. EC can be displayed
as ‘Absolute
EC’ without any temperature correction [ABS EC], as ‘Specific EC’ referenced to
20°C [Ref 20°
C], as ‘Specific EC’ referenced to 25
°C [Ref 25°C] or as a
reciprocal of Absolute EC, which is Absolute Resistivity [ABS RES].
