# Sempling Unit:
# - According to the NYQUEST rule a 100Hz sampling frequency should be enough,
#   but this ins't true if you have to rebuild the signal..
#
# - Get at least 12 samples to compute a RMS value. The sampling time is
#   self computed. Using 12 samples you are sampling at 600Hz

#   0: use 12 BIT

# - Note: If you are using the CT with poor RC circuit as transconductance
#	  amplifier it's needless to set high resolution due to noise...
#	  You will use a high resolution if your probe has good a
#	  transconductance amplifier.
