The 3468 is a 5.5-digit meter. The first post indicates a reading of 2.86XXX volts where XXX is the unsteady portion of the reading. Every 3468 exhibits this behavior.

My 3468, for example, displays 0.2XXXXX (0.3V range) and slowly creeps up to 2.XXXXX volts (3V range) with nothing connected over several minutes. So the whole display is "unsteady" when nothing is connected and works perfectly when provided an input.

Thank you Dave. The creeping is what my 3468 does. Up to 2,86XXX VDC. Not mV, not AC.
When nothing is connected.
Same as yours.
