Current and Voltage RMS Calculations
N
N
The 78M6610+PSU provides true RMS measurements for both current and voltage inputs. The RMS is
obtained by performing the square sum of the instantaneous samples of voltage and current over a time
interval (commonly referred as accumulation time) and then performing a square root of the result after
dividing by the number of samples in the time interval.
