51 • Bump Testing an Instrument with Special Sensors
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
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
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.
