69 • Bump Testing a Gas Tracer
30. After the fresh air purge is complete, the screen will alternate between the gas
readings and the bump test or bump test and calibration results. The results
are indicated with a P (pass) or an F (fail) to the left of the channel units. For a
successful bump test or calibration, the auto calibration values will be
displayed. For a failed bump test or calibration, the gas readings at the end of
the gas application will be displayed. Use the EDIT ENTER button to scroll
between the bump test or bump test and calibration results for the standard
three sensors and the bump test or bump test and calibration results for the
ppm sensor and %volume sensor (if installed). The BUMP
T
LED will stop
blinking and be steadily green if all channels passed the bump test or steadily
red if any channel failed the bump test. In the example below, both the CO and
ppm sensors failed the bump test.
