Action Step
In the Calibration dialog, choose Conductivity monitor - user calibration
in the Monitor to calibrate list. 8
Flush the conductivity flow cell twice with 25 to 30 mL distilled water, using
a syringe attached to the Luer-to-SNAP connector. Leave the syringe at-
tached to the connector so that solution does not drain from the flow cell. 9
Flush the conductivity flow cell with conductivity standard solution, using a
syringe attached to the Luer-to-SNAP connector, then wait until the conduc-
tivity reading is stable. 10
In the Calibration dialog box, enter the theoretical conductivity value at the
current conductivity temperature in the Enter theoretical conductivity
value input field. 11
•
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
Conductivity
values of 1.00 M NaCl, on page 107 .
In the Calibration dialog, click Calibrate. 12
Result: The new conductivity cell constant is displayed in the Conductivity
cell constant/cm box.
In the System Settings dialog box, select Conductivity:Cond temp compen-
sation and set the Compensation factor back to the desired value, default
2.1%. Click OK. 13
Reconnect the system tubing to the conductivity monitor. 14
Factory calibration procedure
Follow the steps below to restore the conductivity cell constant to the factory default
value.
