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”):
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
building biology.
