Temperature compensation
The controller is not equipped with a ther-
mometer and an automatic temperature com-
pensation function for the conductivity meas-
urement reading. However, the measurement
reading can be compensated manually in line
with the current water temperature by entering
a fixed temperature, other than the standard
reference
reference temperature of 25 °C. Refer to the
diagram below for the correction factor used
for the compensation procedure.
Example:
Water temperature setting: T = 11° C
Measured conductivity: C11 = 100µS/cm
Correction factor: Cor = 1,4
Conductivity reading: C25 = 140µS/cm
