for

details.

Cell electronics malfunctioning

Use the Chromeleon Wellness Panel diagnostics to test the electronics (see

Section 5.1

and the Chromeleon Help for instructions). If the variance reading

is outside the tolerance range (less than 1

μS), the electronics are

malfunctioning. Contact Dionex for assistance. The ICS-2100 electronics
cannot be serviced by the user.
