7.3 Error Messages Displayed After
Warm-Up
If there were problems detected during warm-up, error messages that
describe the nature of the problems are displayed immediately following
the analyzer’s 60 second warm-up period.
If problems were detected, the analyzer will not automatically switch
to the Combustion Test HOLD screen after warm-up. The analyzer,
however, can still be used to perform any test that does not depend on
the sensor that is in error. Press the RUN button to manually display the
Combustion Test HOLD screen, and then continue using the analyzer.
The following is a list of the error messages that may appear following
warm-up and their suggested remedies:
Low Battery – Battery voltage is low. Replace batteries per
Section 3.2.

Sensor Missing – Oxygen sensor not installed. Install oxygen
sensor per Section 6.3.
BAD Sensors – The oxygen sensor’s output is too low and can
not be calibrated in the instrument, signifying that the sensor is
depleted and needs replaced. Refer to Section 6.3.
No B-Smart Sensors Installed – There are no B-Smart sensor(s)
installed. Install sensors per Section 6.3.
