RMS detector selection
The following RMS detectors are available in
the instrument:
Impulse
,
Fast
and
Slow
(in
case of Sound measurements) and
100ms

125ms
,
200ms
,
500ms

(in case of Vibration measurements).
The user can easily get into the
Profiles
screen during the measurement performance
from the result view. It is necessary to enter
some profile field (for example,
P(1)
) with the
use of
▲ / ▼ or ◄ / ► push-buttons and press

in case of Vibration measurements) are
measured and saved in the file with the step defined by
Integration Period
parameter as many times as defined
by the
Repetition Cycles
parameter.
The
Logger
function proposes additional registration of some parameters with different step defined by the
Logger Step
parameter. Therefore in fact it can be possible to save to sequences of measured results
– one for
summary results and another for logger results.
When the
Logger
is switched on up to 18 logger results can be saved simultaneously from three independent
profiles of the instrument (
Peak

Max
/
Min
/
Leq / LRxxx
and
LRyyy
for acoustic measurements or
Peak
/
P-
P
/
Max
/
RMS
for vibration measurements) with time step down to
2ms
. The recording of logger results to the
file is stopped after the period, which is equal to
Integration Period
multiplied by
Repetition Cycles
or after
pressing the
<Start/Stop>
push-button or after stopping the measurements remotely.
The summary results are saved in the same file that the logger results. The whole block of the summary results
is added to the file in the end of every measurement cycle.
The figure below illustrates described principles of saving results of the measurement.
