Currently I am getting readings in the high mega-ohm range of my multimeter. If I use other multimeters I get the "OL".
I was wondering if there was a generally accepted definition of "Infinite"
I am working with a specification that states "Infinite Resistance" between all non-ground pins of a connector and the ground plane. What can I use as the practical limit for measurement using standard equipment and practical as far as standard practices?
Circuit is 28V Nominal DC...
