5. Slide the new cell assembly straight into the opening in the component panel
until it stops and the cell cover is flush against the component panel. The
cell’s electronic connector automatically plugs into a connector inside the
Dionex ICS-1100 when you push the assembly into the opening.
6. Tighten the screws on the cell front cover fingertight.
7. Close the side panel door and tighten the two mounting screws.
8. Reconnect the inlet and outlet lines.
9. Turn on the Dionex ICS-1100 power.
10. Calibrate the new cell in Chromeleon. Calibration of a new cell consists of
three parts:
•
Running the offset calibration, which measures the output of the cell
electronics alone and determines an offset value to be applied to raw
conductivity readings.
•
Running the slope calibration, which measures the output of the cell
electronics when a built-in dummy cell, which provides a constant
conductivity reading of 21

S, is automatically enabled. The slope value
is applied to raw conductivity readings.
•
Entering the cell constant measured at the factory. The Dionex ICS-1100
uses the cell constant to determine the measured conductivity.
a. Open the Wellness Panel (see Section 5.1.1 )
b. Under Electric Conductivity Cell Calibration , click Offset Cal .
c. When the offset calibration is complete, click Slope Cal .
d. Click Calibration Details . Under Conductivity Cell Cal Details , enter
the Cell Constant value printed on the front of the cell.
e. In the field next to the Download button, verify that Current is selected
and then click Download to download the new value to the Dionex ICS-
1100.
f. To ensure that the new values are recorded in the Dionex ICS-1100
memory, do not turn off the Dionex ICS-1100 power for at least 1 minute
after downloading.
