Setting switchpoints and parameters
Setting MIN/MAX switchpoints
Activity
Function
Select parameter AL.Lo, set the desired conductivity
and save the setting.
Adjust MIN limit between 1 and 9999 μS/cm or 1 and
5000 ppm.
Select parameter AL.HI, set the desired conductivity and
save the setting.
Adjust MAX limit between 1 and 9999 μS/cm or 1 and
5000 ppm.
Conductivity electrode LRG 1.-..: Setting the correction factor
Select correction factor CF, set the required value and
save the setting.
Once the operating temperature is reached measure the
electrical conductivity of a water sample (at 25°C). Set
the correction factor (in increments) until the indicated
actual value agrees with the reference measured value.
As a result the conductivity readings will be adapted to
the specific conditions of the installation and any devia-
tions during operation will be compensated for.
Conductivity electrode LRG 1.-.. with separate resistance thermometer and LRG 16-9
Enable temperature compensation
Select setting inP and turn rotary button to the right.
The word "YES" appears. Save the setting.
Setting the temperature coefficient tC
Select temperature coefficient tC, set the required
percentage value and save the setting.
Once the operating temperature is reached measure
the electrical conductivity of a water sample (at 25°C).
Set the temperature coefficient (in increments) until the
indicated actual value agrees with the reference meas-
ured value.
If required:
Select correction factor CF, set the required value and
save the setting.
During operation the indicated conductivity reading may
deviate from the reference value due to e. g. dirt deposits
or contamination. Change the correction factor (in incre-
ments) until the indicated actual value agrees with the
reference measured value.
