temperature of the test sample.
IDS sensors measure the temperature with a temperature sensor integrated in
the IDS sensor.
8.2 Temperature compensation
The calculation of the temperature compensation is based on the preset refer-
ence 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
zz
z No temperature compensation (off)
Application tips Select the following temperature compensations given in the table according to
the respective test sample:
The reference temperature and temperature compensation are set
in the menu for the parameter, conductivity (see section 9.4.1 S
ET-
TINGS FOR IDS CONDUCTIVITY SENSORS, page 68).
