Integration period
The Integr. Period parameter defines a
period during which the signal is being
measured (and for some results
averaged/integrated) and a step with which
measured results are logged in the logger file
as Summary Results (see description of the
Logger Setup). The integration period can be
set in the special screen, which is opened with
the â—„ / â–º key.
During the Integration period, the instrument performs series of 1-second measurements/integrations, and every
second averages 1-second results with the results averaged for n-1 seconds. Averaged results are displayed
and renewed every second for the elapsed measurement time (n seconds). In the end of the Integration period
averaged measurement results are saved in the logger file providing that such saving is enabled.
The measurement will stop automatically after this period and start again if the number of Repetition Cycles is
greater than one.
The definitions of the measurement results in which the integration period is used are given in Appendix D.
To set the integration period you should define the required hours, minutes and
seconds fields.
• The appropriate field may be selected with the ◄ / ► key.
• Value of hour, minute and second is changing with the ▲ / ▼ key.
Number of measurement cycles
The Repetition Cycles parameter defines the number of measurements (with
the measurement period defined by the Integration Period) to be performed by
the instrument after the <Start> keystroke. The Repetition Cycles number
values are within the limits [Inf, 1÷1000].
This enables you to make a series of measurements without pressing the
<Start> key and save this series in the file.
For example, if Integration Period is equal to 8 hours and Repetition Cycles is equal to 2, the instrument
performs first integration for the 8-hour period from the measurement start and second integration for the 8-hours
period from the end of the first integration. At the end of each cycle the 8-hours LEQ and other results will be
saved in the file.
Note: In case of the infinite integration period or infinite repetition cycles the measurement must be
stopped manually.
Detector type
The RMS Integration parameter defines the detector type for the integration of
the RMS based results. Two options are available: linear (Lin) and exponential
(Exp). Default value: Lin.
For sound measurements, Leq, SEL, LEPd, Lden and Ln results can be
calculated with both detectors, and Lmax, Lmin, Spl, Ltm3, LTeq results – only
with the exponential detector.
For vibration measurements, RMS result can be calculated with both detectors,
and Max results – only with the exponential detector.
Results definitions are given in Appendix D.
