RMS detector
Available RMS detectors (time constants):
Impulse , Fast and Slow for Sound
measurements and 100ms , 125ms , 200ms ,
500ms , 1.0s , 2.0s , 5.0s , 10.0s for Vibration
measurements.
You can easily access the Profiles screen
from the result view screen. Select some
profile field (for example,
P(1)
) with the ▲ / ▼

OGGING
Summary Results ( Peak , Max , Min , Spl , Leq , SEL , Lden , LEPd , Ltm3 , LTeq , 10 x Ln , EX , SD , LR1 , LR2 ,
OVL , NC , NR for Sound measurements or RMS , Ovl , Peak , P
–P
for Vibration measurements as well as
1/1-octave, 1/3-octave or FFT spectra with Total results and meteo results) 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 and another for so called Logger Results .
When logging is enabled, selected logger results from three independent profiles ( Peak , Max , Min , Leq , LXY ,
LR1 and LR2 for Sound measurements or Peak , P-P , Max and RMS for Vibration measurements as well as 1/1-
octave or 1/3-octave spectra with Total results and meteo results) can be saved simultaneously with time step
down to
2ms . 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.
Note: LXY is an abbreviation for the L (or Spl) result measured with X filter and Y detector time
constant
