47 • Bump Testing an Instrument with Special Sensors
15. The SDM-E2 will apply GAS 1 calibration gas to the instrument for the time
defined by the GAS TIME bump test parameter. The fifth and sixth
channels’
gas reading will be replaced by dashes while the standard 4 sensors are being
bump tested.
At the end of the calibration gas application, the SDM-E2 will determine if the
standard 4 sensors passed the bump test.
16. When the AUTO CAL bump test parameter is set to OFF:
a. The instrument will indicate which standard 4 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. The fifth
channel will then be bump tested with the GAS 2 cylinder.
