Bringing into service
Setting switchpoints and parameters
Setting the MIN/MAX switchpoints
Action
Function
Select parameter AL.Lo, enter and save the desired
conductivity.
The MIN switchpoint is set between
1 and 5000 ppm or 1 and 9999 μS/cm
Select parameter AL.Hi, enter and save the desired
conductivity.
The MAX switchpoint is set between
1 and 5000 ppm or 1 and 9999 μS/cm
Conductivity electrode LRG 1.-..: Setting the correction factor CF
Select correction factor CF, enter and save the
required value.
Alternatively, use calibration function CAL
(from software version "S-13” onward).
Once service temperature is reached, measure the
conductivity of a water sample [at 77 °F (25 °C)].
Change the correction factor in increments until the
indicated actual value matches the reference read-
ing. This adapts the conductivity measurement to
the specific conditions of the installation, or com-
pensates for deviations during operation.
Conductivity electrode LRG 16-9 with resistance thermometer
Switching on temperature compensation
Select setting inP and turn the rotary knob
clockwise. YES appears. Save the setting.
Setting the temperature coefficient tC
Select temperature coefficient tC, enter and
save the desired percentage.
Once service temperature is reached, measure the con-
ductivity of a water sample [at 77 °F (25 °C)]. Change the
temperature coefficient in increments until the indicated
actual value matches the reference reading.
If necessary:
Select correction factor CF, enter and save the
required value.
During operation, the indicated conductivity may differ
from the reference reading, e.g., due to dirt deposits. In
this case, change the correction factor in increments until
the indicated actual value matches the reference reading.
