After searching for a while, I could not find any information about this current probe.
It is very similar to the ubiquitous chauvin arnoux E3N current probe, which I think is rebadged under various other brand names.
But this one does not have the dc-offset trim pot nor the over-range led indicator. In addition, I think this current probe needs a terminating resistor at the connector end, because the gain seems to be wrong when connected to a 1-MOhm scope input impedance.
Any info regarding the connector or the probe will be welcomed.
Thanks,
Diego
