Hi Rich.
Alas, I did connect both of them. One of successors of Lee De Forest taught me the radio science.

: Re: Question
did you have both legs of the capacitor connected? they have to both be making a connection to get a reliable reading.

Subject: Question
Hi Tech Oms at MFJ.
We use your MFJ-269 set, testing antenna equipment.
The set has feature when you can measure capacitance of a separate element - capacitor.
I connected Hi-Q Hi-V 50 pF door knob capacitor and measured its capacitance vs frequency.
I was amazed, because it changes drastically!!! several times 150-200 and more pF with change of frequency.
I see, reactance Xs shall change vs frequency, and very capacitance value shall stand firm and be independent of frequency change.
Why your set measures such way?
Somewhat new in Physics?
Sincerely

Serge
