Alternatively, I present my favorite C meter. The Ballantine 520 measures capacitance from 0.01 pF to 12 uF (not a typo) in 12 ranges.
It's an oldie, but a goodie. I can wave the probes near each other on the lowest scale and watch the meter vary accordingly.
The low end capability makes it valuable to measure PCB trace capacitance.
It is basically a 1 KHz sine wave generator with a precision resistive voltage divider followed by a VTVM calibrated in capacitance
Also, the probes don't respond to C to GND; only between the probe tips, so stray C is avoided. They are simply coax with UT-141 semi-rigid with the ends center conductor exposed as tips.
