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.
