2. On the Wellness Panel under Electric Conductivity Cell
Calibration , click Offset Cal , or touch Run Offset Cal on the ICS-
2000 touch screen.
3. When the offset calibration is complete, click Slope Cal on the
Wellness Panel, or touch
Run Slope Cal
on the ICS-2000 touch
screen.
4. If you are using the Wellness Panel, click Log to record the new
calibration values in the Audit Trail.
5. Disconnect the pump output line from the injection valve.
6. Disconnect the line from the suppressor
ELUENT OUT
port to the cell
inlet and connect the pump output line directly to the cell inlet.
7. Verify that the backpressure is at least 7 MPa (1000 psi).
8. If you are using the touch screens to perform the calibration, open the
CONDUCTIVITY CELL
page (see Figure 5-4 ).
9. On the Wellness Panel under Conductivity Cell Calibration , click
Cell 35 C , or touch
35 C
on the ICS-2000 touch screen. Allow the cell
to reach this temperature and then wait an additional 5 minutes to let
it stabilize. When the temperature has stabilized, “=” is displayed to
the right of the temperature reading on the
CONDUCTIVITY CELL
page.
