4.11 No Detector Response
• Cell not properly installed
Check that the cell is plugged into the component mounting panel and the cell
housing is screwed down until the bottom of the housing is flush against the
sheet metal panel (see Figure 2-2
and Figure 2-10).

Several conditions may cause this condition; see Section 4.4
and Section 4.5
for details.
• Cell electronics malfunctioning
Use the Wellness panel to test the electronics with a dummy cell (see
Section 5.1
and the Chromeleon Help for instructions). If the conductivity
reading with the dummy cell is outside the tolerance range, the electronics are
malfunctioning. Contact Dionex for assistance.

Conductivity exceeds limit is displayed in the Chromeleon or Chromeleon
Xpress Audit Trail, follow the instructions in Section 4.1
. For additional
troubleshooting guidance, refer to the suppressor manual. Suppressor manuals
are included on the Dionex Reference Library CD-ROM (P/N 053891).

Dilute the sample (see Section 3.10.3
