Aging slightly changes the cell constant, e. g. by 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 measuring cell by calibrating with the control standard in the following ranges: 0.450 ... 0.500 cm-1 (e.g. TetraCon 325, nominal cell constant 0.475) 0.800 ... 0.880 cm-1 (cells with a cell constant of approx. 0.840) 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 delivery condition, the calibrated cell constant of the meter is set to 0.475 cm-1 (conductivity measuring cell, TetraCon 325). AutoRead (stability control) Display calibration data Calibration evaluation The calibration procedure automatically activates the AutoRead (stability control) function. You can have the data of the last calibration displayed (see section 4.4.6). After the calibration, the measuring instrument automatically evaluates the current status of the calibration. The evaluation appears on the display and in the calibration record.

The index will help you to find the topics that you are looking for. Glossary Adjusting 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 Conductivity Measured parameter Measured value Molality ba75794e05 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. 06/2013 Characteristic quantity of a conductivity measuring cell, depending on the geometry. 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. The measured parameter is the physical dimension determined by measuring, e. g. pH, conductivity or D.O. concentration. 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 is the quantity (in Mol) of a dissolved substance in 1000 g solvent. 53 Lists Cond 3210 Reference temperature 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 electrolytic resistivity. 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 Salt content Stability control Standard solution Temperature coefficient The absolute salinity SA of seawater corresponds to the relationship 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. General designation for the quantity of salt dissolved in water. Function to control the measured value stability. The standard solution is a solution where the measured value is known by definition. It is used to calibrate a measuring system. Value of the slope α of a linear temperature function. TRef Temperature compensation Temperature function Test sample 54 = 1 Meas * 1 + a * (T - TRef ) 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. Name of a mathematical function expressing the temperature behavior of a test sample, a probe or part of a probe. 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. ba75794e05 06/2013 Cond 3210 Lists Index A O Authorized use . . . . . . . . . . . . . . . . . . . . . . 10 Automatic switch-off . . . . . . . . . . . . . . . . . . 15 AutoRead . . . . . . . . . . . . . . . . . . . . . . . . . . 29 Operational safety . . . . . . . . . . . . . . . . . . . 10 P Precautions . . . . . . . . . . . . . . . . . . . . . . . . . 9 B Battery compartment . . . . . . . . . . . . . . 13, 45 R Reset . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 42 C Calibration . . . . . . . . . . . . . . . . . . . . . . . . . 35 Calibration evaluation . . . . . . . . . . . . . . . . 35 Cell constant . . . . . . . . . . . . . . . . . . . . . . . 35 Control standard . . . . . . . . . . . . . . . . . . . . 35 Copyright . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 D Dataset . . . . . . . . . . . . . . . . . . . . . . . . . . . . 38 Date and time . . . . . . . . . . . . . . . . . . . . . . . 22 Default settings Measured parameter . . . . . . . . . . . . . . 42 System settings . . . . . . . . . . . . . . . . . . 43 S Safety . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 Sample display . . . . . . . . . . . . . . . . . . . . . . 7 Saving . . . . . . . . . . . . . . . . . . . . . . . . . . . . 38 Scope of delivery . . . . . . . . . . . . . . . . . . . . 13 Setting the date . . . . . . . . . . . . . . . . . . . . . 14 Setting the time . . . . . . . . . . . . . . . . . . . . . 14 Socket field . . . . . . . . . . . . . . . . . . . . . . . . . 8 Stability control automatic . . . . . . . . . . . . . . . . . . . . . . . 26 T Temperature compensation . . . . . . . . . . . . 30 Temperature measurement . . . . . . . . . . . . 27 E Energy saving feature . . . . . . . . . . . . . . . . 14 I Initial commissioning . . . . . . . . . . . . . . 13, 14 Initialize . . . . . . . . . . . . . . . . . . . . . . . . . . . 42 K Keys . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 M Measured value display . . . . . . . . . . . . . . . 17 Measurement data memory Edit . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40 Erase . . . . . . . . . . . . . . . . . . . . . . . . . . 40 Storage locations . . . . . . . . . . . . . . . . . 38 Measurement dataset . . . . . . . . . . . . . . . . 38 Measuring . . . . . . . . . . . . . . . . . . . . . . . . . 28 Measuring menu . . . . . . . . . . . . . . . . . . . . 31 Menus (navigation) . . . . . . . . . . . . . . . . . . 17 Messages . . . . . . . . . . . . . . . . . . . . . . . . . . 18 ba75794d05 06/2013 55 Lists 56 Cond 3210 ba75794d05 06/2013 Xylem |ˈzīləm| 1) The tissue in plants that brings water upward from the roots; 2) a leading global water technology company.
