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.

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.
