3. Press Enter Menu, then DISPLAY, VOC and GRAPH.
Selecting GRAPH shows you a graph of response versus time. This is a real
time display. A single peak on the graph indicates the presence of VOCs. In
graph display, another line of text displays the fullscale range and the analysis
time.
At the end of the TVOC analysis, if any VOCs were present, the area of the
TVOC peak will be shown at the bottom of the Report display.
NOTE: If the detected concentration exceeds the alarm level, stored in the library, then the
audible alarm may sound at the end of the analysis. If an alarm sounds, an alarm
acknowledge box will open. Press YES to acknowledge the alarm condition and to
silence the audible alarm.
NOTE: While an analysis is in progress it is not possible to change to GC mode. Wait until
the current analysis is complete before attempting to change modes.
To stop the analysis before it is complete, press the Start Stop key.
If you stopped the analysis after the sample was injected onto Column V, you
must wait for the duration of the analysis time for the column to be flushed
before beginning another analysis.
