Unsuccessful Calibrations

In the unlikely event that a problem occurs during a calibration process, the "Results" screen will show
the calibration status as "Unsuccessful".

(1) On the "Results" screen, select "Continue".
(2) On the "Calibration Unsuccessful" screen, do one of
the following:
a) For zero gas calibrations:
To retry the zero gas calibration, select "Repeat
Calibration".
To return to the previous calibration values, select
"Close".
b) For span gas calibrations:
To do a span gas calibration for another gas, select
"Select Another Gas".
To retry the span gas calibration, select "Repeat
Calibration".
To return to the previous calibration values, select
"Close".
If "Close" is selected, on the dashboard, a gray check mark
indentifies the points that are affected by the unsuccessful
calibration. The gas readings for these sample points are
below the alarm threshold but may not be completely accu-
rate.
