There are two electrode calibration methods: Standard Solution calibration and Constant calibration.
The calibration described above in the section Calibration refers to the Standard Solution method
(the most accurate calibration method, assuming the calibration buffer standard is accurate and
fresh).
To select the Constant calibration method use Parameter P5 described below in the Programming
Parameters – Conductivity section.
The temperature compensation coefficient of the meter setting is 2.0%. However, the conductivity
temperature coefficient is different for solutions of a different variety and concentration. Use the
chart below for common solution types (use Parameter P4 as described below in the Programming
Parameters – Conductivity section).
The meter can perform an automatic non-linear temperature compensation in distilled water for
readings below 10 µS/cm.
Note: When the coefficient for the temperature compensation is set to 0.00 (no compensation), the
measurment value will be based on the current temperature.
Solution
Temperature compensation
coefficient
NaCl salt solution 2.12%
5%NaOH solution 1.72%
Dilute ammonia solution 1.88%
10% hydrochloric acid solution 1.32%
5% sulfuric acid solution 0.96%
Important Note: When one or more of the programmable parameters is changed by the user from
its original factory default condition, the parameter’s code shown below, is displayed in the upper
right corner of the display as shown in diagram below (in this case, Parameter P Tcc). If more than
one parameter is changed, only the code from the first parameter change is displayed.
