RKI Instruments SDM-2012 Standalone Configuration - Manual (Page 72)

67 • Bump Testing a Gas Tracer
25. If your Gas Tracer does not have a %volume sensor installed, or if the GAS
menu item in Edit Mode is set to Std, continue with step 29.
If a %volume sensor is installed in your Gas Tracer and if the GAS menu item
in Edit Mode is set to ALL, the Gas Tracer screen will prompt you to change
the calibration cylinder connected to the GAS 2 fitting on the back of the SDM-
2012.
26. Change the GAS 2 calibration cylinder to the %volume CH
4
calibration cylinder
and press and release the EDIT ENTER button on the SDM-2012 control
panel.
NOTE: Even though the pump will continue to run, the SDM-2012 will not
continue the bump test of the Gas Tracer until you change the
calibration cylinder and press and release the EDIT ENTER button.
27. GAS 2 calibration gas will then be applied to the %volume sensor.
28. The SDM-2012 will analyze the results.
• If the %volume sensor passed the bump test, continue with step 29.
• If the %volume sensor did not pass the bump test, and if AUTO CAL is set
to OFF, continue with step 29.
• If the %volume sensor did not pass the bump test, and if 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.
