15. The SDM-E2 will apply calibration gas to the instrument for the time defined by
the GAS TIME bump test parameter. A “B” will appear to the right of the gas
reading to indicate that calibration gas is being applied for a bump test.
At the end of the calibration gas application, the SDM-E2 will determine if the
bump test passed.
16. When the AUTO CAL bump test parameter is set to OFF:
a. The instrument will indicate which channels passed or failed the
bump test with a P (pass) or an F (fail) to the right of the “B” which
indicates it is a bump test result. The bump test gas readings at the
end of the gas application will be displayed.
b. 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, 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.
