Page 16: Measuring The Salinity
5 Measuring The following approximate values apply for C.tdS: 0.50 Monovalent salts with 2 ion types (NaCl, KCl, etc.) 0.50 Natural waters/surface water, drinking water 0.65 to 0.70 Salt concentration of aqueous fertilizer solutions NOTE! The stated values for "C.tdS" are only reference values that are good for esti- mates but are not suitable for precise measurements. -
Page 17: Temperature Compensation
5 Measuring NOTE! This measurement is intended exclusively for measuring seawater. The salin- ity measurement is not suitable for determining the salt concentration of other saline solutions. A measurement according to TDS is recommended in such cases, see Page 15. Select the measurand If the device has been configured for a different measurand in a user- defined operation, first change the measurand (see "Parameter "InP":... -
Page 18: Linear Temperature Compensation "T.lin
5 Measuring 5.7.2 Linear temperature compensation "t.Lin" If the temperature compensation type is not precisely known, the "linear tem- perature compensation" is used in practice (see "Parameter "t.Lin": compen- sation coefficient", page 25). This involves making the simplified assumption that the ratio of the temperature to the concentration will take a linear trajec- tory across the measuring range being considered. -
