4.4.3 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:
z Nonlinear temperature compensation (nLF)
according to EN 27 888
z Linear temperature compensation (lin)
with adjustable coefficients of 0.000 ... 3.000 %
/K
z No temperature compensation (off)
Note
The reference temperature and temperature compensation are set in
the conductivity measuring menu (see section 4.4.4).
Application tips Select the following temperature compensations given in the table
according to the respective test sample:
