Bump Testing a GX-2009 • 27
for a description of calibration results.
16. The SDM-2009 will then purge the system with fresh air for the time defined by
the Air bump test parameter.
17. After the fresh air purge is complete, the GX-2009 screen will alternate
between the gas readings and the bump test or bump test and calibration
results. For a successful bump test, the gas readings at the end of the gas
application will be displayed. For a successful automatic calibration, the auto
calibration values will be displayed. For a failed bump test or automatic
calibration, the gas readings at the end of the gas application will be displayed.
If all channels passed the bump test, the BUMP
T
LED will turn solid green. If
any channels failed the bump test, the BUMP
T
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.
