Temperature compensation
The calculation of the temperature compensation is based on the
preset reference temperature, 20 °C or 25 °C. It appears on the display
as Tr20 or Tr25.
You can select one of the following temperature compensation
methods:
Nonlinear temperature compensation (nLF) according to EN 27
888
Linear temperature compensation (lin) with selectable
coefficients of 0.000 ... 3.000 %/K
No temperature compensation (off)
Note
The reference temperature and temperature compensation are set in
the conductivity measuring menu (see page 66).
