4.4.5 Determining the cell constant (calibration in control standard)
Why determine the cell
constant?
Aging slightly changes the cell constant, e.g. due to coatings. As a
result, an inexact measured value is displayed. The original characteristics of the cell can often be restored by cleaning the cell. Calibration
determines the current value of the cell constant and stores this value
in the meter.
Thus, you should calibrate at regular intervals (we recommend: every
6 months).
Procedure You can determine the actual cell constant of the conductivity measur-
ing cell by calibrating with the control standard in the following ranges:
The cell constant is determined in the control standard, 0.01 mol/l KCl.
Cell constants outside the ranges quoted above cannot be calibrated.
In the default condition, the calibrated cell constant of the meter is set
-1
(conductivity sensor LF413T).
Stability control
(AutoRead)
to 0.475 cm
In calibration, the Stability control function (AutoRead) is automatically
activated.
Display calibration data You can have the data of the last calibration displayed (see section
4.4.6).
Calibration evaluation After calibration, the meter automatically evaluates the current status of
the calibration. The evaluation appears on the display and in the calibration record.
Determining the cell
constant
For this calibration procedure, the Measuring cell setting must be set to
cal in the Measurement menu. Proceed as follows to determine the cell
constant:
1 Connect a conductivity measuring cell to the measuring instru-
ment.
2 In the measured value display, select the conductivity parame-
ter with <M>.
3 Start the calibration with <CAL>.
The cell constant that was calibrated last is displayed.

described here.
Index The index will help you to find the topics that you are looking for.
Glossary
Adjusting To manipulate a measuring system so that the relevant value (e.g. the
displayed value) differs as little as possible from the correct value or
a value that is regarded as correct, or that the difference remains
within the tolerance.
AutoRange Name of the automatic selection of the measuring range.
Calibration Comparing the value from a measuring system (e.g. the displayed
value) to the correct value or a value that is regarded as correct.
Often, this expression is also used when the measuring system is
adjusted at the same time (see adjusting).
Cell constant, k Characteristic quantity of a conductivity measuring cell, depending on
the geometry.
Conductivity Short form of the expression, specific electrical conductivity.
It corresponds to the reciprocal value of the resistivity.
It is a measured value of the ability of a substance to conduct an
electric current. In water analysis, the electrical conductivity is a
dimension for the ionized substances in a solution.
Measured parameter The measured parameter is the physical dimension determined by
measuring, e.g. pH, conductivity or D.O. concentration.
Measured value The measured value is the special value of a measured parameter to
be determined. It is given as a combination of the numerical value and
unit (e. g. 3 m; 0.5 s; 5.2 A; 373.15 K).
Molality Molality is the quantity (in Mol) of a dissolved substance in 1000 g
solvent.

Fixed temperature value to compare temperature-dependent
measured values. For conductivity measurements, the measured
value is converted to a conductivity value at a reference temperature
of 20 °C or 25 °C.
Reset Restoring the original condition of all settings of a measuring system.
Resistance Short name for the specific electrolytic resistance. It corresponds to
the reciprocal value of the electrical conductivity.
Resolution Smallest difference between two measured values that can be
displayed by a meter.
Salinity The absolute salinity S
of seawater corresponds to the relationship
A
of the mass of dissolved salts to the mass of the solution (in g/Kg). In
practice, this dimension cannot be measured directly. Therefore, the
practical salinity according to IOT is used for oceanographic
monitoring. It is determined by measuring the electrical conductivity.
Salt content General designation for the quantity of salt dissolved in water.
Stability control Function to control the measured value stability.
Standard solution The standard solution is a solution where the measured value is
known by definition. It is used to calibrate a measuring system.
Temperature coeffi-
Value of the slope of a linear temperature function.
cient
Temperature compen-
sation
Name of a function that considers the temperature influence on the
measurement and converts it accordingly. Depending on the
measured parameter to be determined, the temperature
compensation functions in different ways. For conductimetric
measurements, the measured value is converted to a defined
reference temperature. For potentiometric measurements, the slope
value is adjusted to the temperature of the test sample but the
measured value is not converted.
Temperature function Name of a mathematical function expressing the temperature
behavior of a test sample, a sensor or part of a sensor.
Test sample Designation of the test sample ready to be measured. Normally, a test
sample is made by processing the original sample. The test sample
and original sample are identical if the test sample was not processed.
