P3.1 Cell constant Selection
Choosing the right conductivity cell is a decisive factor for obtaining accurate and reproducible
measurements.
One of the fundamental parameters to consider is to use a sensor with the right cell constant in relation to
the solution under analysis.
The following table relates the cell constant of the sensor with the measurement range and the standard
with which it is preferable to calibrate:
Access this setup menu to select the cell constant related to the sensor you are using:

0.1

1 -default-

10
For each of the 3 selectable cell constants the instrument stores the calibrated points. By selecting the cell
constant, the previously performed calibration points are automatically recalled.
P3.2 Calibration method
Access this setup menu to select automatic or manual recognition of the standards with which to perform
the calibration:

Automatic:
-default- The device automatically recognizes up to 3 of the following standards
84 µS/cm, 147 µS/cm, 1413 µS/cm, 12.88 mS/cm e 111.8 mS/cm;

Custom
: the device can be calibrated on a point with a manually entered value.
Note: To obtain accurate results, it is advisable to calibrate the device with standards close to the theoretical
value of the solution to be analysed
P3.3 and P3.4
Temperature compensation in Conductivity measurement doesn’t have to be confused with pH
temperature compensation.
