Clamp-On Current Meter Readings
Got curious with my new clamp-on meter this afternoon. Made the following current readings (one fully charged 24 series battery; converter turned off): .13 amps - parasitic/residual current with e...

Inductive DC ammeters as Matt Collie pointed out are near useless at low scale. Worse than useless, they are misleading. Horribly so.
For low current measurement, use your DMM, on the 200ma scale if you want to stay out of the land of OZ.
For PRECISION measurement of low value amperage I use a MANGANIN 20 amp shunt and a 4.5 digit DMM (6.5 digit when I get real serious). This would be worthlessly precise for most RV applications.
Measuring very low values of amperage with an inductive meter would be similar to timing a 100-meter dash with a sundial.
