Micro-PWC OPERATOR’S MANUAL
64 Trend Displays
established to display a periodic signal which repeats every 60 seconds, and a collection rate of 10 sec-
onds is configured, then the display will show six points per period of the signal (
Figure 6-7 ).
If this trend is compressed six times, the display will show only every sixth sample. The resulting display
will be a straight line since every sixth sample has the same value (
Figure 6-8 )
If the display is compressed seven times, the resulting display will be identical to the original, since the
value of the eighth sample (first sample plus 7) is the same as the value of the second, the value of the fif-
teenth point is the same as the value of the third, and so on. (
Figure 6-9 ).
If the display is compressed five times, the resulting display will be the mirror image of the original wave-
form (
Figure 6-10 ).
