[Boatanchors] ohm meters

[Gerry Steffens]

My son borrowed (we will call it that any way) my Fluke digital multi-meter
a while back, leaving me with my older digital Micronta.

When trying to determine resistances, the digital Micronta is very unstable,
jumping around a lot, particularly on field coils, transformers, etc.  I
don't remember how the Fluke responded.

I also have a good Simpson 260  8P and an old RCA Wv-38A, both measure
seemingly precisely and with good stability.

Do all digital meters exhibit this instability?  Are some more stable than
others?  Is this instability related to sampling rate and more?

Thanks for the info in advance.
