Default DMM ac readout with signal

What is the 'normal' readout when measuring AC with your DMM when you're just connecting the probes together? Or when measuring a circuit without any signal. This should of couse be 0mV but my DMM always gives me a couple of mV.

If you take 5-10 cm cable the reading should be more or less zero but with 1-2 meters you will get something in the cables from electrical fields around you.
