Is that high impedance millivolt range on those Anengs of any use or just a gimmick?
Does it show zero with a wire between the input jacks? Does it still show zero with a 1Meg resistor?
Somebody said that voltages below 5µV are rendered as zero
I suppose that's to hide the meter's offset voltage. What happens to this "helpful" feature in REL mode? Does it activate when the displayed value is below 5µV? Does it activate when the actual input voltage is below 5µV? Does it just go away?
