17. The SDM-2012 will analyze the results.
•
If the bump test passes, continue with step 18.
•
If the bump test fails, and AUTO CAL is set to OFF, continue with step 18.
•
If the bump test fails, and AUTO CAL is set to ON, a calibration will
automatically begin and 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.
At the end of the calibration gas application, the SDM-2012 will analyze the
results.
18. If your GX-2012 does not have a %volume sensor installed, or if the GAS
menu item in Edit Mode is set to Std, continue with step 20.
If you have a %volume sensor installed in your GX-2012 and if the GAS menu
item is set to ALL, GAS 2 calibration gas will be applied to the %volume sensor
for the time defined by the GAS TIME bump test parameter.
19. The SDM-2012 will analyze the results.
•
If the bump test passes, continue with step 20.
•
If the bump test fails, and AUTO CAL is set to OFF, continue with step 20.
