LEQ detector selection
Available LEQ detectors (time constants): Impulse, Fast and Slow.
Time constants are applied always to the Lmax, Lmin, L(SPL), Ltm3 and Ltm5
results and to the Leq, LE(SEL), LEPd and Lden results in case the Exponential
LEQ detector is selected in the General Settings screen (see Appendix D).
4.4 SETTING ALARM THRESHOLDS FOR DOSE METER – ALARM
The Alarm position is active only in the Dosimeter
function and is described in detail in Chapter 11.6.
4.5 CONFIGURING DATA LOGGING – LOGGING
Summary results (L(SPL), Leq, LE(SEL), Lden, LEPd, Ltm3, Ltm5, 10 x Ln, OVL, Lpeak, Lmax, Lmin,
EX, SD) and spectra are measured and saved in the file with the step defined by the Integration Period
parameter as many times as defined by the Repetition Cycles parameter (path: <Menu> / Measurement
/ General Settings).
The instrument enables also additional registration of some results with different step defined by the
Logger Step parameter (path: <Menu> / Measurement / Logging / Logger Setup). Therefore, it is
possible to save in parallel two sequences of measured results – one for Summary Results (SR) and
another for so called Logger Results or Time History results (TH).
When logging is enabled, selected logger results taken from three independent profiles will be saved
simultaneously with time step down to 100ms. Recording of logger results to a file is stopped after the
period, which is equal to Integration Period multiplied by Repetition Cycles or after stopping a
measurement manually.
Summary Results are saved in the same file with Logger Results. Blocks of summary results are
recorded to the file in the end of every measurement cycle.
The figure below illustrates principles of logging measurement results.
