You can probably make the needle move simply by staring hard at it!


I have one which is 1mA FS, but it's only 70 ohms. It's sensitive enough
that rubbing my finger across the faceplate generates enough static to
bounce the needle everywhere. The scale is calibrated for a type K
thermocouple, IIRC.
