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 selectable
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 page 65).
