Refer to Table 3-1 for a listingand description of these messages.Depending on the nature of the problem and mode of the analyzer, theanalyzer behaves as follows when a problem occurs:• If an “error” and/or “warning” problem occurs during the CAL cycle: theERROR indicator starts flashing, and an E* and/or W* message ap-pears at the conclusion of the calibration cycle.• If an “overrange” problem occurs during the CAL cycle: the calibrationcycle is immediately aborted, the ERROR indicator starts flashing, andan OR message appears.• If an “error” and/or “overrange” problem occurs during an efficiencytest: the efficiency test is immediately aborted, the ERROR indicatorstarts flashing, and an E* or OR message appears.• “Warnings” are ignored during an efficiency test.To acknowledge and clear an error, warning, or overrange message,perform the following:1. Press the left SELECT key to acknowledge the E*, W*, or OR mes-sage, and to stop the ERROR indicator from flashing.If the analyzer reports more than one problem, continue to press theleft SELECT key as many times as necessary to view and clear allmessages, until either the analyzer starts through another calibrationcycle, or the word RUN or FUEL appears in the left display.
