CS547 Conductivity and Temperature Probe and A547 Interface

Correction of Ionization Errors: Figures 8.1-1 and 8.1-2 show the amount of

correction applied by the example program to compensate for ionization effects on

the measurements. Also shown is an ideal correction. Factors were derived by

measuring the standard solutions described in Section 2.2 with values of 0.0234,

0.07, 0.4471, 07, 1.413, 2.070, 3.920, and 7.0 mS cm
