[Elecraft] CAPACITOR VALUES

K2 kit #3803 arrived here in NZ within ten days of the order going in, a =
very prompt and delightful response from Elecraft.   Duly performed the =
inventory and found Victoria's reputation for getting everything right =
remains untarnished.

Encouraged by the book to do so, I checked all the capacitor values.   I =
had just purchased an autoranging DMM with a capacitance measuring =
feature (the first time I have ever owned such a device) and began to go =
through the packets.   All the monolithic caps checked out fine, so did =
the electrolytics but, when I turned to the NPO caps, I began to get =
very strange readings from most of them.

For example:

    1 pf    read     21 pf
    10pf    read    35PF
    12pf    read     38pf
    20pf    read    51pf
    27pf    read    62pf
    33pf    read    70pf
    39pf    read    77pf
    47pf    read    90pf

    and so on up the scale ad nauseum.

My first inclination was to think that either my DMM was faulty (this =
was its first job, after all) or that Elecraft had tracked down a supply =
of dud parts (unthinkable).   However, a little reflection reveals that =
all the capacitors of a any given value gave the same meter reading and =
that, as the marked values increased, so did the indicated values,albeit =
by a factor of around 2:1.   All of which leads me to suspect either the =
DMM or the way I am using it.

Can anyone help this greenhorn?
