Number of measurement/integration repetitions after the
<Start> key pressure.
This enables to make a series of measurements without
pressing the <Start> key and save this series in the
results file.
Type of integration of RMS based results (RMS
detector): Linear or Exponential. The IEC 61672-1:2013
standard requires Linear integration, without time
weighting, however in some countries old regulation
refers to the Exponential RMS integration with standard
time weighting: Fast or Slow.
Linear type of integration of RMS based results (RMS
detector), without time weighting according to the
IEC 61672-1:2013 standard.
Exponential type of integration of RMS based results
(RMS detector), where averaging is a continuous
process that weighs current and past data differently.
The amount of weight given to past data as compared to
current data depends on the exponential time constant.
In the exponential averaging, the averaging process
continues indefinitely.
Method for calculation of statistics for RMS results: with
linear detector (Lin) or exponential detector (Exp), e.g.
Impulse, Fast or Slow time constant.
Definition of the day and night periods required by local
standards: 6–18h and 7–19h. These limits are used for
the calculation of the L(den) function.
Time frame for the "Rolling Leq" calculation. The Rolling
Leq is presented as LR+<time frame>. For example, if
the Rolling Time is equal to 30 minutes, the appropriate
result will be named as LR30 and calculated each
second as Leq integrated during last 30 minutes.
Virtual broadband level meters, which calculate the set
of results with own weighting filter (Filter) and exponential
detector time constant (Detector).
Weighting filter applied in the profile in accordance with
most applicable world standards:
- for sound measurements: Z, A, C, B, U, AU, LF,
- for vibration measurements:
o acceleration: HP, HP1, HP3, HP10, Wh,
o velocity: Vel1, Vel3, Vel10 and VelMF,
o displacement: Dil1, Dil3 and Dil10.
