S-max measurement
It is standard S-max measurement as the maximum vector amplitude of displacement.
Spectrum measurement
The triggering type is displayed bellow the spec word. The fs below the Range means sampling frequency. The
t below the Lines is the time signal length, which is used for one spectrum. The df is the frequency resolution
between lines.
The information in top right contains averaging (2/8), speed (42.1Hz) and bellow them cursor position (16.5Hz),
order (f / speed = 0.392), value (0.132mm/s) and total RMS of spectrum (0.619mm/s).
The Band fmin defines the frequency of HP filtering, which is used for DC part removing. If you do not expect
any important lines bellow 10Hz, use the 10 instead 1. The initialization time of 1Hz filter is much longer then
10Hz.
