General measurement settings: Start Delay,
Start Sync., Integration Period, Repetition Cycles,
RMS Integration and Day Time Limits.
Delay between pressing the <Start> key and the
start of measurement integration.
Synchronization of the measurement/integration
start to the nearest full minute or hour of the
instrument real-time clock. It helps to measure in
full cycles.
Time of averaging of Summary Results: from 1
second to Infinitive. For example, with 8 hours
integration period the LEQ result will be averaged
for 8 hours. In case of Infinitive, the measurement
will last until the user presses the <Stop> key.
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.
