2. If the appropriate table is not displayed, select it from the Choose
Table drop-down list.
3. Select a new variable by clicking on the appropriate drop-down list
under the Variable column. For a demonstration of how to use the
context-sensitive variable selector, see “Using the context-sensitive
variable selector” on page 1-42.
4. Enter the component’s concentration percentage in the appropriate
cell under the Nominal Value column. To ensure accuracy, this value,
which is compared to the GC’s analysis results at the end of the
validation run, should be taken from the documentation provided with
the gas cylinder.
5. Enter a value in the appropriate Percent Deviation cell. If you enter
10 in this field, and the GC’s analysis result for the component differs
from the component’s Nominal Value by ±10% or more, then an alarm
is generated.
6. To copy a component variable to the next empty row, click C + Copy.
The component will be increment to the next available component—
for example, from Ammonia to Benzene. The Nominal Value and
Percent Deviation values will also be copied.
Note
You can select and copy more than one component at a time.
If there are no components available, instead of copying the
component, MON 20/20 will display the following message:
