Default Re: Avometer Movements

No luck with this one.

The particular unit I am working on is incredibly insensitive. Even connecting directly to the movement is seeing such little activity. My current source is measuring the current flowing, so I know there isn't an open circuit. The movement moves a little when I leave the uA ranges and enter the mA ranges, but still not enough. Moving the shunt sees some change in activity. Introducing the magnets seems to do very little indeed.

I'd have thought I would at least see something significant with such strong magnets around the movement?
