Band fmin[Hz] - HP filtering
Almost in all measurements you should define the HP filtering of input signal. You set it in Band fmin[Hz]
parameter. You can select the none, 1, 2, 10 and user filter. The none value is available only for direct
measurement without integration. The none value does not mean the DC part measurement. The HP filter on
A/D converter is always used. But no additional filter is used. The frequency range with none filtering begins on
0.35 Hz (-3dB point). See the response graph.
