On the ETCR-50FA sensor the calibration tag says 50mV/1000A. For my measurement of a Magnetic Pulse device operating at 3 to 5kHz, I determined the calibration in my application is approximately 50mV/16.5A. I determined this calibration by comparing the measurements to a Hantek CC650 clip-on ammeter when measuring the current in the same conductor around 650A which is the upper limit of the CC650. The ETCR-50FA current probe does give a voltage out corresponding to the derivative of the current so if you are measuring a sine wave current, that will introduce a 90degree phase shift, which is easily accounted for. A nice feature of the ETCR-50FA is it can measure high currents without saturating like most of the other types of clip-on ammeters. I would have given it a 5-Star if the calibration was more accurate.
