Mains Signaling Measurement are based on: either the corresponding 10/12-cycle r.m.s. value
interharmonic bin or the rms of the four nearest 10/12-cycle rms value
interharmonic bins per IEC 61000-4-30 Limit setup for Monitor mode follows
EN50160 “Meistercurve”
Time Synchronisation Optional GPS430 timesync module provides time uncertainty ≤ 20 ms or ≤ 16.7
ms
