8.6 Shaped Time Domain
In the SHAPED TIME DOMAIN operating mode, an evaluation method is used in the
time domain, which ensures gapless recording of the weighted peak or RMS values
related to a selectable personal protection standard. The result is displayed as an expo-
sure index in %.
The applied measurement method is described in international standards and is gener-
ally referred to as Weighted Peak Method or Weighted RMS Method respectively.
In addition to the numerical result display, a logarithmically scaled bar display shows the
exposure index graphically over the entire measurement range of the probe. Instead of
the bar display, a time curve graph can also be displayed.
8.6.1 Measurement settings
The SHAPED TIME DOMAIN operating mode is only available for the EHP-50F/G and
BFD-400-1 probes.
The MEASUREMENT SETTINGS menu provides quick access to the most important
measurement settings for the selected operating mode.
