For example my other meter Minipa ET997TR http://www.goodluckbuy.com/minipa-et-997tr-et997tr-3-0-lcd-handheld-digital-multimeter-with-temperature-test.html does not suffer with that(on its separate AC mV range), as well as UT-61e - there is something about meters for $50 range (...
Again, you should ask yourself why you expect that - if you short the probes together, that's 0V. If you leave the probes disconnected, there's nothing in particular defining the voltage across the probes, so the readout is undefined. The megaohm impedance of the multimeter itself will ...
