OctaveDivider
octave division (type of filters):
1 – octave filters
3 – 1/3 octave filters
5
FirstFreqIndex
index of the first filter; the exact centre filter frequency in Hertz
according to its index is given by the following formula:
f = 1000 · G
i/b
– for odd value b
f = 1000 · G
(2i+1)/(2b)
– for even value b
where:
G = 2 – for filter base 2
G = 10
0.3
– for filter base 10
i – filter index
b – octave division
6
N
number of octave or partial octave filters
7
T
number of total results; total results, depending on the measurement
mode, are calculated with the following filters:
in vibration measurement mode:
Total[1] – measurement with HP filter
Total[2] – measurement with a filter from the second profile
Total[3] – measurement with a filter from the third profile
in sound measurement mode:
Total[1] – measurement with A filter
Total[2] – measurement with C filter
Total[3] – measurement with Z filter
8
Filter
spectrum measurement filter:
0 – HP
1 – Z
2 – A
3 – C
5 – B
7 – U
8 – AU
9
Detectors
type of RMS detectors for spectra:
0 – linear detector (Linear)
1 – exponential detector Fast
2 – exponential detector Slow
10
Band
frequency range:
0 – full band (Full)
1 – audible band (Audio)
2 – ultrasonic band (Ultra)
11
MinMaxDetectors
type of RMS detectors for Max and Min spectra:
0 – linear detector (Linear)
1 – exponential detector Fast
2 – exponential detector Slow
