I decided to build a 5 Decade Capacitor, using .5% Polystyrene capacitors, that would cover a range of .0001mf to 1mf in 5 steps. I used a 6 position switch, so that the 1st position would be 0 and I could read my residual capacitance (about 6pf).
This gives me the capability to quickly check the linearity of my capacitance measuring devices over a large range of capacitance. Also, because they are precision Polystyrene capacitors I have a wide range of low leakage capacitance for use in filter design, integrators, sample hold scenarios etc.
It was an easy, fun and rewarding little project, that I thought I would share.
