Monkeh:
61E? Slow autoranging? It's pretty fast compared to most meters <$200.

In ohms it seems to jump all over before settling down after 2 or 3 seconds. It could be the god-awful probes.  :palm: They really are bad. Like $10 meter bad.

Yes, the probes suck. This is known. Clean them.

I did clean them with IPA several times. I'll just use better probes. It seems to work fine with the Pomona's so its not the meter, just the probes making me think its the meter.  :phew:

Lightages:
When cleaning the probes, you need to get a little aggressive. You can use chrome cleaner or Brasso. If you use isopropanol, then you should use fine steel wool to clean them. The plastic mold release and/or any plastic coating that might be there from molding the handles needs to be physically broken up to remove it. Do not use sand paper or abrasive pad as this will scratch and pit the plating on the probe tips and cause corrosion in the end.
