Agilent U1272a strange zero readings in AC measurement mode. And the same for AC voltage modes. Has anyone encountered such a problem? |

with leads disconneted, if so they act as antenna and pick anything in the air, induction etc ... if you remove them is the meter show less ... some brands will force a zero value ... the fluke and amprobe i have at my job don't show zero value, disconnected leads nothing to worries about :-+ |

True RMS converters (with rare complicated exceptions like in 34461A/65A/70A bench meter) do not properly go down to 0. True RMS meters that show zero in AC mode actually fake it by displaying zero instead of readings below certain level. |

That's normal, this was discussed on this forum before. |
