Operating Information
Click the TIMEBASE up/down pointers to change the time scale of the divisions of the chart.
Each division mark along the baseline (1, 2, ...10) can be made to represent from 30 seconds to
2½ hours, providing from 5 minutes to 25 hours of continuously displayed samples. The chart
updating rate is determined by the time scale selected.
Click on the Continuous box, in the lower right corner, to enable or disable continuous charting.
When this box is checked, the chart scrolls continuously after reaching the 10 division, and the
oldest samples are lost off the left of the chart. When Continuous is not checked, the chart
stops displaying new results after reaching the 10 division, and all subsequent measurements
are lost.
Click the up/down pointers for each measurement variable (GAS, TEMPERATURE and
PRESSURE
) at the right of the chart to change the scaling of that value on the chart. The
display of each measurement variable may be turned on or off by choosing the appropriate On
or Off switch at the right of the chart.
If your measurements do not chart properly, try using a higher or lower value scale or time base
than the one displayed. Adjust these scale factors before starting the monitoring operation.
A running display of latest sample Gas, Temperature and Pressure is also shown in the
bottom-right corner of the chart.
Use the buttons at the bottom of the chart to control real-time monitoring. Choose Go to clear
the chart and start real-time monitoring display, Stop to stop real-time monitoring and Copy to
copy the data from the chart as text information to the Windows Clipboard. This information can
be pasted from the clipboard into any Windows application, such as a spreadsheet or word
processor.
Finally, choose Close to close the Monitoring window.
