lcf meters

circuit does work, with some comments. First, it depends on the manufacturer of the 4011 that you use. Some work without modification, others require a little tweaking. I built 3 of these and had to add a 43 pf cap across the second gate of the 4011 to get the meters to read linearly. There was a complete page of discussions on this in, I believe, the May issue of EPE in the readers letter section.

Hope that helps you...Mike

lcf meter schematic

Hi,

I finished my LCF meter from EPE, but i have problems with it. It measures ower 1uF exactly the double capacity, so 2*cap. value. Below 1uF, it works perfectly. I used the firmware, from EPE. What can be the problem? The another thing is, that when I turn on the unit, it displays "capacitor time out" message. When i take a wire, and make a shortcut between the measuring points, and aftet a sec. I remove it, it works.

Any idea????
