My VOM includes a basic capacitor tester, two ranges from 50pF to 100uF. I tested some of my ceramics disks, micas, and 'film' (that's what they called in Japanese), all purchased new. There were some shocking differences between the measured value and the indicated value. The worst were some 473 squarish shaped, red-brown 'film' caps that read a little over 2uF. Not one but all six. I tend to think it must be a meter problem but many other caps tested very close to their indicated values. So I don't know what to believe. Again, these are all new caps, purchased within the last year or so, not cheap ones or discount items. Is this kind of deviation common?

Not a meter problem, if some measure good. It is excessive leakage that is giving the high readings. Send those Chinese caps back.

As a test of your particular VOM, try measuring a good capacitor and then add a few megohms in parallel and see if the capacitance reading changes.
