Action
In the Run Data pane of System Control, read the current Cond temp.
Tip:
If Cond temp is not showing, click the Customize icon. In the Customize dialog
box, under the Run Data Groups tab, select to view Cond temp.
In the Calibration dialog box, enter the theoretical conductivity value at the
current conductivity temperature in the Enter theoretical conductivity
value input field.
If a certified conductivity standard solution is used, use the supplied
•
theoretical conductivity value.
If a manually prepared 1.00 M NaCl calibration solution is used, see the
•
graph for conductivity value at the current temperature Graph for con-
ductivity value, on page 330.
In the Calibration dialog box, click Calibrate.
Result: The new conductivity cell constant is displayed in the Conductivity
cell 1 constant/cm box. The new constant should normally be 40 ± 10 cm
The date and time for the calibration are also displayed.
In the System Control toolbar, click the End icon to end the run.
In the System Settings dialog box, select Conductivity:Cond temp compen-
sation and set the Compensation factor back to desired value, default 2.1%.
Click OK.
