To show the example is the best way how to learn the process of measurement.
The example of requirements for the Set:
Meas 1: RMS overall value in mm/s, frequency band 10-1000Hz, from channel 1
Meas 2: RMS overall value in g, frequency band 500-25600Hz, from channel 1
Meas 3: Spectrum in mm/s, range 400Hz, 1600 lines, from channel 1, number of average 4
Meas 4 Spectrum in g, range 3200Hz, 3200 lines, from channel 1, number of average 8
When the measurements definition is made ( see the New Meas creation section) everything is ready to make
the real measurement. Push the Start button (green triangle button). For stopping the measurement use Stop
button (the red square button). If the Trigger Mode is set to single, then only one measurement is taken.
Every graph on the screen contains one measurement. More screens with graphs can be developed.
The description of each graph is in the top.
Example:
The translation: Meas No.1, RMS value, Channel 1, Applied band filter 10-1000Hz, Number of Samples of the
signal 4096, Time length of signal 1s. The Signal means the time signal, from which the evaluation was made.
The translation: Meas No.3, Spectrum from Channel 1, Range 400Hz, Lines 1600 Time length of signal 4s, 4
signals for 4 AVG used, speed 17.7Hz
Input Buffering
Measured signal is collected into the input memory. The analyze procedures read the signal data from the
memory and compute all required results, which are displayed on the screen. In the case, when too many
results are required, the computation is slow and displayed graphs are not in time - they are delayed. We are
talking about Real Time (RT) graphs (you see the actual results) or about Non Real Time (non RT) graphs
(delayed results).
This information is displayed in the right upper corner - Measuring RT or Measuring non RT.
