Figure 6-12 is an example of a trend chart as readings are logged. (Figure 6-8 and
Figure 6-10 contain more information on the trend chart window.)
Figure 6-12 Trend chart display during data logging.
When logging is complete, the Marker, Pan, and Zoom softkeys can be used review
the data. Note that pressing the Graph key followed by the Trend Chart softkey does
not retain the data in the display.
If greater than 100 readings are logged the readings are decimated - grouped
together and represented by decimation points (see “Trend Charts” and “Reading
decimation”).
Stopping the application
Pressing Stop Save or Stop No Save stops data logging before the duration (time or
number of readings) is reached. All readings logged to that point are saved or
discarded depending on the key pressed.
