The conductive conductivity measured at
the fluid temperature is converted to the
reference temperature
[TREF]
.
Changing the reference tem‐
perature
If the reference temperature [TREF] is
changed, the temperature coefficient
[TCOEFF] has to be recalibrated, see
Ä Chapter 9.1.2 ‘Calibration of the
temperature coefficient’ on page 60
Adjustable process for temperature com‐
pensation
n
[off]
– Temperature compensation is
switched off. It is measured
based on the set reference tem‐
perature.
n
[lin]
– Linear temperature compensa‐
tion, see
Ä Chapter 10.5 ‘Tem‐
perature correction variable’
on page 82
, for the temperature
range permitted for the sensors.
The reference temperature
[TREF]
can be set between 15 °C
and 30 °C.
n
[nLF]
– Non-linear temperature compen‐
sation according to DIN EN
27888 for natural water, between
0 °C ... 35 °C. The reference tem‐
perature
[TREF]
can be switched,
20 °C / 25 °C.
