diy egor jitter

[rr]

Not long ago somebody referring to their EGOR system spoke
about the output moving about a bit (jitter). I recently discovered
a sensor that did the same thing. It appears that the resistence of
the pump cell varies on a sensor-to-sensor basis.

By increasing the capacitance (slowing the loop) of C9, from 0.1uf
to 0.22uf, the loop stabilized.

I looked for your email & could not find it. Anyone that has a jittering

output may want to try this. On a built circuit you can just add another

0.1uf cap in parallel with the one already there. Would anyone having
the jitter prob & trying this get back to the list? Thanks.

hth's,
