If your VCO is in the audio range and you can hear it, tune a second 
VCO exactly one or more octaves higher until it gets into the range 
that your meter can read. Then for each octave you added, halve the 
freq reading.

Example: vco tuned two octaves up reads 440 Hz. Divide by two twice 
to get 110 Hz.

Can any way give me a way to determine the frequency
of a VCO or LFO below 200 Hz? I have a Fluke 87-III
and that is the slowest frequency it can detect.
