Is there anyway to accurately measure the
capacitance of an electrolytic capacitor
in the range of 10uf to 100uf.

These capacitors are to be used at frequencies
under 1 Hz.

Everytime I try to use my meter to measure, the
capacitance will change from one range scale
to the next, I guess because the frequency changes too.
When I use a typical non-electrolytic capacitor
these changes in readings are not there.

I have been thinking of making
a simple RC inverter oscillator and using
the resulting frequency to determine the
true capacitance in the small signal
application I want to apply them to.

Maybe there are non-electrolytic capacitors
in the 10uf to 100uf range but if so
I have never heard of them before.

I do not know if any of you have ever seen
the SCI FI movie THIS ISLAND EARTH
but I am in need of several of those
fantastic capacitors.

I am trying to get a reading
within 1% of reality.

Help here is appreciated.
