between the gas readings and the bump test or bump test and calibration
results. 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 four sensors and the bump test or bump test and calibration results
for the %volume sensor (if installed). If all channels passed the bump test, the

BUMP

LED will turn solid red. If all channels passed the calibration, the CAL
S LED will turn solid green. If any channels failed the calibration, the CAL S
LED will turn solid red.
