That might happen using a capacitance meter than does
not measure the series and parallel resistance. The GR
bridge does, which is not to say that you might not be
right.

Dick,

what I meant to say is the following:

At 1kHz, a 500 pF capacitor with a 500,000 ohm resistance in parallel is
equivalent to the series of of 702 pF capacitor and 144,200 ohm resistior
(using the well known parallel-to-seriel translation formulas).

So, if your meter has the ability to separately measure the series resistance
and capacitance, it should correctly indicate 702 pF, i.e. a value higher than
that marked on the capacitor.
