The problem was resolved 10k resistor on nutrition.

Hello, help solve the problem. EPE PIC collected magnetometer logger, startup does not define RAM, switching s5 wrote LIMIT REACHED. Installation that everything is fine, what could be the problem, thanks.

From outside my didgeridoo looks exactly as your magnetometer

Oh it's just pipe with sensors, magnetometer is looking like this:

Thank you very much ivconic
you can upload pictures of your work fgm3 position please

One ready and already in use... and one to go:

Does it work correctly fgm3h this device? Do you have tried to?

Is this question addressed to me?
I had chance only to work with FGM-3 (not h version) so far.
For me and my needs FGM-3 is quite alright.

My original msg seems to have been erased. The brief answer is that the magnetic cores of FG sensors are critical. I'm guessing that the shape of the hysteresis curve for the material chosen determines how well the FG works, esp. how sensitive it is. The US Navy has a complete electronics course online (NEETS something, if I go look up the exact name, this msg will be erased. If you have trouble, write me.) In chap. 3, on special amplifiers, they have a few pages describing 'magnetic amplifiers', which use DC coils to amplify relatively large AC currents. If you already know a little electronics you should be able to follow along if you begin with that section. I was fascinated by it. I intend to learn more about magnetic 'circuits'. Without ferromagnetic cores, there are no magnetic circuits.

Thanks Qiaozhi. Maybe that happened. At least my messages got through.
