n c.c. (factory)
This parameter displays the cell constant (factory setting).
The cell constant (factory setting) is determined by factory calibration made during sensor
manufacturing.ThisvaluecanbesetinCommissioning→Measurementsetup→Sensorsetup.
The cell constant is indicated on the sensor or cable label.
n c.c. (adjusted)
This parameter displays the cell constant (adjusted).
The cell constant (adjusted) is a cell constant that has been calibrated and is set by calibration
action.
Whenthesystem’scellconstantisadjustedon-linebycalibrationusingaprocesssolutionor
buffer solution, a new cell constant is logged here. The difference between this value and the
default value set at factory shipment will not be large. If there is a large difference between them,
check whether the sensor is broken or contaminated.
n Temp. comp. 1
This parameter shows the temperature compensation method for 1st measurement. The setting
ismadeinCommissioning→Measurementsetup→Temp.comp.
n Temp. comp. 2
This parameter shows the temperature compensation method for 2nd measurement. The setting
ismadeinCommissioning→Measurementsetup→Temp.comp.
2nd measurement does not imply that two measurements can be made individually, but it means
thattwotypesofcompensationmethodscanbecongured,whichenablestwophasestobe

process and washing solutions.
n Sensor Ohm
This parameter represents the non-compensated resistance of the sensor.
n Sensor wellness
At the Sensor wellness window, the soundness of a module is displayed. A larger number of n
in each gauge indicates that the parameter concerned is sound. A gauge is indicated for only
those parameters whose sensor wellness setting is “enabled,” while a bar (----) is displayed if the
sensor wellness setting is “disabled.”

settings. For details, see section 10.1.7.
The “Reset wellness data” button can reset wellness data.

NOTE
When a sensor is replaced, the replacement can be recorded manually into a logbook. (Refer to
thegure9.7.)
