3. Press the
key to continue, and enter in the Uncertainty values from the certificate.
NOTE: If the calibration certificate does not include uncertainty values, use the default
2 % setting.
4. Press the
key to continue, and enter the energy value for the calibration blend.
NOTE: The calculated value shown on the display is calculated using the same C6+ Ratio of
C6/C7/C8 as is used in the stream calculations. This value may differ to the value on the
certificate which may use a Hexane only energy content. Use the Calculated Value from the
screen to avoid nuisance alarms during calibrations.
5. Press
to save and close the screen.
Wait for the oven to reach the operating temperature
1. From the main menu, navigate to the Hardware menu and select Heaters.
2. Wait for the Current PWM for the Oven Heater to be less than 45. This should take
approximately two hours from when power is applied.
Clear Alarms
1. From the main menu, navigate to the View menu and select Current Alarms.
2. Press [2] to acknowledge and clear all alarms.
3. Press
to return to the Main Menu.
Purge Calibration Gas
1. From the main menu, navigate to the Control menu and select Single Stream.
2. Select the 4-Cal stream and check the Purge Stream for 60 seconds option.
3. Let the GC run for at least 30 minutes.
Calibrate the GC
1. From the main menu, navigate to the Control menu and select Halt to stop the
current analysis.
2. When the analysis cycle finishes, select Calibration from the control menu.
3. Select Purge Stream for 60 seconds and a Normal calibration type and press
start the calibration cycle.
4. Confirm at the end of the calibration cycle no alarms where generated. If alarms
were activated, refer to the manual that is included on the MON2020 CD-ROM that is
shipped with the GC.
Putting into Service
1. From the Main Menu, navigate to the Control menu and select Auto Analysis.
2. Select Purge stream for 60 seconds and press
The 370XA is now analyzing the stream gas. For more configuration and operating
instructions, refer to the manual that is included on the MON2020 CD-ROM that is
shipped with the GC, and is available online at www.rosemountanalytical.com.
to start the analysis cycle.
