6.5 Trend graphics
Pressing on the Zoom display changes the display to a graphical mode in which the
average measured value is shown on a time scale. The “Live” value is also digitally displayed in
a text box. The time scale (X-axis) and the primary value scale (Y-axis) are set in the “DISPLAY
SETUP” menu (Section 7.7.2).
The screen displays the trend of up to 41 averages of the measurement for each time interval.
The FLXA202/FLXA21 samples the measurements every second. The trending graphic also
shows the maximum and minimum measured values in that interval.
For example, if the time scale is set to 4 hours, then the trend is shown for 4 hours prior to the
actual measurement. Each point on the trend line represents the average over 4×60×60/41 =
351 measurements (seconds).
NOTE
Updating the trend screen setup resets the current trend graph and starts a new one.
