Setting:
"Signal"
Peak / RMS
The following illustration shows the difference in the evaluation of a
pulsed signal if displayed as an average value reading or a peak value
reading ("RMS" and "Peak"):
peak value: 10
avg. value: 1
With the switch set to "Peak", the meter will display the full power flux
density of the pulse (10 µW/m² in the graph). With the switch set to
"RMS", the meter will take the mean of the power flux density over the
total period of time, for instance 1 µW/m² in the above graph (= ((1 x
10) + (9 x 0)) / 10).
With the switch set to "Peak" or "Peak hold", the display will show the
"RMS value during the pulse", which is a common practice in the build-
ing biology.
