RKI Instruments SDM-2012 Standalone Configuration - Manual (Page 71)

Bump Testing a Gas Tracer • 66
In this case continue with step 31.
NOTE: If the GAS menu item in Edit Mode is set to Std, there will be no fresh
air adjustment result for the ppm combustible sensor and pressing and
releasing the EDIT ENTER button will have no function.
23. The SDM-2012 will apply GAS 1 calibration gas to the standard three sensors
for the time defined by the GAS TIME bump test parameter.
24. The SDM-2012 will analyze the results.
• If all three standard sensors passed the bump test, continue with step 25.
• If any of the standard three sensors did not pass the bump test, and if
AUTO CAL is set to OFF, continue with step 25.
• If any of the standard three sensors did not pass the bump test, and if
AUTO CAL is set to ON, a calibration will automatically begin and GAS 1
calibration gas will continue to flow. The CAL
S
LED will begin to flash
amber.
NOTE: GAS 1 calibration gas will continue to be applied so that the total gas
application time is the time defined by the GAS TIME calibration
parameter. This time includes the time that the instrument was being
bump tested. If the GAS TIME calibration parameter is set to 90
seconds and the GAS TIME bump test parameter is set to 30
seconds, the instrument will sample gas for an additional 60 seconds if
the bump test fails to bring the total exposure time to 90 seconds.
