Action
Note the current temperature of the calibration solution in the Conductivity
flow cell as displayed in the Cell Temperature field. This value is required
for setting the reference temperature (see Section 3.11.4 Set reference tem-
perature, on page 74).
Make sure that Enable Temperature Compensation is checked.
In the Calibration screen, enter the theoretical conductivity value at the
current temperature in the Set Conductivity field and then tap Calibrate to
carry out the Conductivity calibration.
Note:
•
If a certified conductivity standard solution is used, use the supplied theo-
retical conductivity value corresponding to the temperature in question.
•
If a manually prepared 1.00 M NaCl calibration solution is used, read the
conductivity value at the current temperature from the graph for conduc-
tivity of the 1.00 M NaCl as a function of temperature presented below.
