The conductive conductivity measured at the fluid temperature is converted to the reference tem‐
perature
[TREF]
.
Changing the reference temperature
The temperature coefficient must be recalibrated if the reference temperature is changed.
Adjustable process for temperature compensation
–
[off]
–
Temperature compensation is switched off. It is measured based on the set refer‐
ence temperature.
–
[lin]
–
Linear temperature compensation via the temperature range permitted for the sen‐
sors. The reference temperature can be set between 15 °C ... 30 °C.
–
[nLF]
–
Non-linear temperature compensation according to DIN EN 27888 for natural
water, between 0 °C ... 35 °C. The reference temperature can be switched,
20 °C / 25 °C.
