Temperature compensation

5.7.1 Nonlinear temperature compensation "nLF" according to EN
27888
Recommended area of application
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.
If the device has been configured for a different measurand in a user-
defined operation, first change the measurand (see "Parameter "InP":
selection of a measurand", page 21).
• 0.0 to 70.0 ‰ (g/kg)
NOTE!
The salinity measurement features dedicated automatic temperature com-
pensation, independent of the menu settings concerning temperature com-
pensation for conductivity.
The conductivity and TDS of aqueous solutions depend on the temperature.
Thanks to the temperature compensation, the solution is counted back to a
uniform reference temperature.
The normal reference temperature, which is preset in the device, is 25 °C.
The nonlinear temperature compensation for natural waters ("nLF" according
to EN 27888) is sufficiently accurate for most applications, for example in the
area of fish breeding and for measuring surface water and drinking water.
The "nLF" compensation is recommended for conductivity measurements
between 60 µS/cm and 1000 µS/cm.
