Virtual broadband level meters, which calculate the
set of results with own weighting filter (Filter) and
exponential detector time constant (Detector).
Profiles can be programmed together in the Profile
window if the instrument works in the Level Meter,
1/1 Octave or 1/3 Octave modes, or individually if
the instrument works in the Dosimeter mode.
Weighting filter applied in the profile for all results
except Lpeak in accordance with most applicable
world standards: Z, A, C, B, LF.

Exponential RMS detector time constant applied in
the profile: Impulse, Fast or Slow for sound results
like Leq, Lmax, Lmin, LE, LEPd, Lden, L, Ltm3 and
Ltm5.
Digital filter that compensates some effect:
Microphone, Diffuse Field, Windscreen,
Outdoor Environment and Outdoor Airport.
Digital filter that compensates the microphone inner
noise. It is switched on by default, however it is can
be switched off for electrical measurements (e.g. for
laboratory calibration measurements).
Digital filter that compensates the diffuse field effect.
The microphone supplied with the instrument
(ACO 7052E - 35mV/Pa, prepolarised ½”
condenser microphone) is designed for sound
measurements in free field conditions.
