2.5 Monitoring Measurements In Real-Time
You may wish to analyze a particular sampling point via the WinLog97 program's Monitoring menu. To use this Monitoring chart, the analyzer must be connected to your PC.
Choose Monitoring from the WinLog97 menu to bring up a chart display like the one illustrated in Fig
Fig
The Monitoring chart shows the gas concentration (in blue), temperature (in red), and pressure (in green) as the sample is being measured by the 3650 instrument. The chart is updated directly from instrument measurements, at a rate determined by the time scale set in the TIMEBASE box at the lower right corner of the chart.
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, as shown in Table
