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 averaging 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
exponential averaging, the averaging process
continues indefinitely.
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.
Definition of the integration periods for calculating
the LR1 and LR2 results.
