My quick answer, U1272A this is unique over our planet, it supports all three known conversions.
100mv/A , 10mV/A , 1/mV/A.
Other brands might support 10mV/A and 1/mV/A, or just the 10mV/A.
I do not have any details about KYORITSU.
DEREE DE-208A this supports "sensor mode"
HIOKI this has also an model this supports "sensor mode" (but I do not have memory of the actual model).
