33 • Bump Testing Instruments with Standard Sensors
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
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
LED will turn solid
green. If any channels failed the bump test, the BUMP
LED will
turn solid red.
