Period of signal recording before the first trigger condition
fulfilment. The length of pre-recording depends on
sampling rate.
Marker is used to mark (or highlight) special point or
event during the measurement. For example, for an
airplane flight it can be marked the beginning and end of
the block of logger results in which this event occurred.
In case of point markers there is only one record (start)
in the logger file. Markers are activated in the result
presentation screen by pressing the arrow keys.
Position in the Menu that enables to set up the markers
– name them and define them as Event or Point type.
Screen that enables setting the 1/1 Octave - 1/12 Octave
spectrum parameters: Band, Filter and Detector.
Position in the Logger Results screen that switches on /
off spectra saving as a time-history in a logger file.
Frequency range of 1/1 - 1/12-spectrum. Depending on
the function and mode of the instrument the frequency
range can be selected: for sound measurements as
Audio or Full and for vibration measurements as Full.
Weighting filters for the 1/1 Octave - 1/12 Octave
analysis: HP, A, B, C, Z for sound and HP for vibration
analysis.
Type of integration of RMS based results for 1/1 Octave
- 1/12 Octave analysis: Linear, Fast or Slow for sound
measurements and Linear for vibration measurements.
Screen that enables setting the FFT spectrum
parameters: Band, Filter, Screen, Lines and Averaging.
