Step 17 Verify Calibration Data
This step assumes that the unit has completed calibration and moved
back into Hold mode. The user will need to verify several things before
moving into Run mode.
17A Click on the Peak Find icon on the right side of the Operation
screen. A chromatogram will load at the bottom of the screen.
This is the last cycle of the calibration stream. There will be a
delay as the data downloads. There is a tab for C3-C6+ (Heavy
Components) and N2-C2 (Light Components). C3-C6+ is
displayed first. If no chromatograms display, click the Re-read
button.
17B Look at the date/time below the chromatogram. This time should
coincide with the start of the last cycle of the calibration process
that was just run. This signifies that the calibration data was
accepted (no alarms, etc.). If this displays an older date and time
(generally indicating factory calibration), the new calibration data
has not updated. If this occurs, an alarm should show up on the
Operation screen.
17C Verify that there are seven (7) peaks: C6+, C3, iC4, nC4, neoC5,
iC5 and nC5. The second double-looking peak from the left is a
composite peak of C2-. This may or may not be labeled but is
not used in calculations.
17D Place the vertical line of the cursor over the small tick mark on
nC5, and verify the time in the upper right-hand corner of the
chrom is approximately 160 seconds. It is not critical that it be
exactly 160 seconds but should be within 3 or 4 seconds.
17E Click on the N2-C2 tab, and verify that there are four (4) peaks:
N2, C1, CO2 and C2. The first peak on the left is a composite
C3-C6+ (Heavies)
