Vallon VMH3CS Mine Detector

[Ferric Toes]

Hi Eric,

You said that you've attached the plot for gold/silver, but the plot is actually the one for gold/copper. Oops!

Oops is right. Here is the correct one. A bit more complex as it deals with the different coil sizes.

Hi!

Does anyone have the manual for the VMH3CS?
Mine is acting up and I would like to check the manual.

I can host it for others if I could get a copy.

TOP right: 4532A

Bottom right: 8 pin SOIC is OPA627; 16 pin SOIC is DG442.

Many thanks kingjl.

In my PCB OPA627 is marked 48760 and DG442 is marked 48790.
You have feedback with other pcb as it is marked on mine?
I think start retro engineering. I wanted to understand how schematic structured.
If not problems for you I would like to write you in private message about the work to have an exchange of ideas.
Regards

[KingJL]

I really don't have much to add... the identification of the subject components was accomplished by others!!

[lucafa]

Ok kingjl
No problem.
however you are very kind.
