AmprobeINSTRUMENTS AMP-320 DIGITAL MULTIMETER, CLAMP, 3 5/6DIGIT

Does the BackLight stay on, or does it turn off after a few minutes?

One Answer says the light turns off ten minutes. Could this be the meter turning off at ten minutes? ...and the Backlight stays on till then?

This item states it can be shipped to an fpo, but when i try to order, amazon says the item cannot be shipped to an fpo. why?

Amp-320: what is the max resolution for ac and dc current, using the clamp, not the test leads, i.e. how low in ma or micro amps can be measured?
