the 4 pin versions drive the output relative to the ref pin
I use one for a current sensor with the inductor testing.
It's so easy to use the output and ref pin since
I put the CRO lead on one and the earth clip on the other
and if the output is inverted I just swap the pins.
I think there is little output between ground and output in the case of the 4 pin versions
