For the Aztec/AMP II Guys

[Pawnee Bill]

When you analyzed a piece of brass with Aztec or in the AMP II, did you get the same setting number as what was listed on the AMP website for the same brass?

Negatives those settings are standard mode.

This is correct; there is zero correlation between the codes listed on AMPs website and the AZTEC codes generated when you analyze a piece of brass.

I will say though, I routinely get identical AZTEC codes across different batches of brass in the same lot though. Whatever it's doing to analyze, it's at least consistent.

Just remember heat is energy and induction is precise and predictable method of transferring energy. I am just taking a guess here but my bet is it monitors the temp of the neck using a very precise infrared pyrometer while monitoring the amount of energy that was used to reach that temp. Exact composition of the brass and mass of the neck would vary from cartridge to cartridge, lot to lot, neck thickness, neck length etc and require minute differences in the amount of energy required to get the brass to temperature. I am no expert but it seems it would be a simple calculation to accurately transfer the precise amount of energy to raise temp xxxx amount if you have the right numbers to plug in. AMP is truly a most amazing little piece of equipment. Apologies for the small derail

Those of us who have built the GinaErick Induction annealer have a basic idea on how the Aztec mode works. Aztec mode heats the brass until the brass melts. At the melting point with induction the current will drop off sharply and as ID’d from the GinaErick annealer. AMP uses this current drop to detect the exact moment/timing the brass melts and then backs off the timing from there using a formula they developed through their testing with Vickers Hardness.

and as usual I over thought the process, thanks
