DESCRIPTION
Normal mode is used for line cycle integration for noise filtering, or for high-speed multiple channel use when
noise is not a problem. The selection for Average Weight (
each thermocouple or DC volts channel, or how many samples over which the root mean square (RMS) is
calculated for AC volts. As there are 32 samples per line cycle, setting
automatically enable line cycle noise rejection.
Note: Due to hardware constraints, weights greater than
