3.
Connect the CS547 and A547 or probe and interface to the datalogger
using the wiring described in Section 4. Enter the following program into
the datalogger.
The calibration solution temperature must be between 1°C and 35°C; the
polynomial in step 11 (P58) corrects for temperature errors within this range.
The solution constant of 1.408 mS cm
-1
(for prepared solution mentioned above),
entered in step 13 (P37), is valid only for a 0.01 molal KCl solution. Location 8
[Kc (cm-1)], generated by step 14, will contain the resultant cell constant.
