F SENSe POWer AVG SMOothing STATe OFF ON The ON parameter activates a smoothing filter for modulated signals in the Continuous Average mode and OFF deactivates it The smoothing filter is a steep edge digital lowpass filter used to Suppress variations of results caused by low frequency modulation This parameter should be activated to reduce variations in results due to modulation when the size of the sampling window cannot or should not be exactly adapted to the modulation period If the selected sampling window is 5 to 9 times larger than a modulation period the variations in display are normally sufficiently reduced With smoothing deactivated 300 to 3000 periods are required to obtain the same effect With smoothing deactivated the sampling values are considered equivalent and averaged in a sampling window which yields an integrating behaviour of the measuring instrument As described above optimum suppression of variations in the result is thus obtained when the size of the sampling window is exactly adapted to the modulation period Otherwise the modulation can have a considerable influence even if the sampling window is much larger than the modulation period The behaviour can be considerably improved by subjecting sampling values to weighting raised von Hann window which corresponds to video filtering This is exactly what happens with activated smoothing Since the smoothing filter increases the inherent noise of the sensor by a
