10.1.1 Measurement
Select a measurement parameter from Conductivity, Concentration, and Conduct. + Concentr.
The setting of the measurement parameter changes the menu structure in Error conguration,
Display setup, etc. accordingly.
10.1.2 Congure sensor
This section describes how to congure the sensor to be connected.
l Measuring unit
Either /cm or /m can be chosen here.
The process values will be expressed in S/cm or S/m.
l Cell constant (factory)
The cell constant given at factory shipment is set.
When a new sensor is connected, set the new cell constant which is indicated on the sensor.
When a cell constant is changed, a calibrated cell constant (c.c. (adjusted)) will be the same
value of the new cell constant (factory) after resetting an old one.
10.1.3 Temperature settings
Select the temperature element used for compensation from among Pt1000 or NTC30k. Select
the same type as the temperature element that is actually connected.
Celsius (°C) or Fahrenheit (°F) temperature units are available. If the unit is changed, the
following values are also recalculated automatically to the new unit:
• Manual temp.
• Reference temp.
• Temp. coefcient
• Temp. ranges in the matrix
10.1.4 Temperature compensation
l Temperature compensation
Two methods can be used: Automatic and Manual. Select Automatic when a temperature
element is used or Manual when a manually set temperature is used.
NOTE
When Manual is selected on the Temperature compensation, a process temperature should
be set in the “Manual temp.” A temperature shown on the Main display is this manually set
temperature.
l Reference temperature
The temperature compensation function converts the measured conductivity value to that at the
reference temperature. The reference temperature can be changed. The default value is 25ºC.
