BirdManPhil:
That sucks. Maybe this would be a good complement to the tweezers then

Am I mistaken or does that seem to have the accuracy I'm looking for?

Display range and accuracy aren't the same thing. That device is much lower end the the ST2832 I shared the accuracy chart for.

I question the ability to accurately measure the 0.0001 pf stated in that devices spec sheet.

KungFuJosh:
Agreed, certainly not on that meter.

At 200kHz the ST2832 can measure 10fF (the pF is a typo on the chart in that position top right corner), but that's in it's lowest accuracy range.

KungFuJosh:
If you want to spend $20,000 on an LCR, you can get into the fF range better, but still probably 5% accuracy at best.
