4.4.6 Entering the salt content (salinity)

A salt content correction is required in the oxygen concentration mea-
surement of test samples with a salt content of more than 1 g/l. To do
this, you have to enter the salinity equivalent of the test sample (range
0.0 - 70.0) and to switch on the salinity correction.
1 Determine the salinity of the test sample.
2 Press the <CAL> key repeatedly until Sal appears on the dis-
