P7.0: Dissolved Oxygen Parameters (DPr)

This Set Up menu allows you to set the barometric
pressure and the salinity value of the sample to be
measured. You are given the option to use mmHg (Hg)
or kilo Pascal (PA) barometric pressure units. The
Salinity (SAL) value to be entered will be based on ppt
and is available in mg/L (ppm) Set Up menu.
