6.5.6 Clearing stored values
To clear all the values stored in the instrument via the WinLog97 program, choose the Clear Data
command from the Logger menu. Since this action will clear the storage memory of the instrument, a
warning appears first. Choose OK to bring up the next dialog box to confirm the clear action. Choose
Clear to start the memory clear operation. A message, Reset should be completed appears in this
box when the task is finished.
Note: You can accomplish the same thing passively, by simply allowing the analyzer to overwrite a set of stored
values with new ones.
6.6 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 instrument must be connected to your PC. Choose Monitoring from
the WinLog97 menu to bring up a chart display.
The Monitoring chart shows the gas concentration (in blue), temperature (in red), and pressure (in
green) as the sample is being measured by the 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.

*This chart's updating rate is independent from the acquisition rate (see
sampling intervals on page 18).
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.
