4.4.6 Entering the salt content (salinity)
A salt content correction is required in the oxygen concentration mea-
surement of samples with a salt content of more than 1 g/l. To do this,
you have to enter the salinity equivalent (the measured salinity) of the
test sample (range 0.0 - 70.0) and to switch on the salinity correction.
Note
With the Multi 1970i, you can measure the salinity. How to proceed is
described in section 4.5.3 M
EASURING THE SALINITY on page 38.
