e. Once the GAS 2 calibration gas has been applied for the
appropriate amount of time, the SDM-E2 will determine if the sixth
channel passed the bump test and will indicate a P (pass) or an F
(fail) to the right of the “B” which indicates it is a bump test result. If it
passed, the following screen will appear.
f. The BUMP
T
LED will continue to flash amber while the docking
station performs a fresh air purge for the time defined by the AIR
TIME bump test parameter. After the purge is complete, The BUMP
T
LED will turn solid green.
g. Continue to step 18.
• If any of the standard four channels fails the bump test:
a. A calibration is automatically started on the standard four channels
and the GAS 1 calibration gas will continue to be applied. The
current gas readings will be displayed along with the bump test
results. A “C” will appear next to the channels indicating they are
being calibrated.
