Hi, All,
We were talking about the AADE L/C meter in another thread. I pulled the manual (with schematics) off archive.org and posted it here:
It uses an interesting two-frequency design with an LM311 and a PIC16. AFAICT no source code is available.
Cheers
Phil Hobbs

Note that I increased the range of mine to 1 uF and 1 Henry by having it send the 3 frequencies via RS232, and doing the math on the PC. I could do it on the PIC 18F14K22 with the 32 bit mathlib and an OLED display I suppose. But the logging facilty via PC is in a way nice, hard copy.. The 1 H makes it suitable for measuring toroids, E-cores, etc.
Neil Hecht passed away three years ago, and on his AADE website, the LC meter is shown discontinued. I have a copy of his source assembly code, that he gave out, dated 1995. It worked fine, but I believe that he made various improvements after that.

Here's someone else's version... There is a firmeare download to go alone with it.
MFJ also has a non-kit version availble.
Cheers
Good to have the manual. :-) Thanks! Ed
Win, do you have hex file or source code for Neil heckt lc meterIIB
I REQUEST TO SHARE A COPY IF YOU CAN.
