Basic Power Accuracy
The GN610B is calibrated and checked at 53 Hz voltage and current inputs using burden resistors. During calibration burden resistors are
attached to three voltage channels to enable current measurements.
Specifications are given for the 2.5 Ω burden. Using the 1.0 Ω or 10.0 Ω burden will give different current ranges but identical results.

With the right setup the LEM sensor can be used for this range, however this input range is not specified in the LEM current sensor
data sheet.
