How adjust portable barometer?
I picked up an old Taylor SMT-5-51 aneroid barometer at a sale. It seems to read pressure okay, and I can calibrate it with a screw on the back.
It also has an elevation scale, which seems to be stuck at an unreasonable value. I think you are supposed to rotate the front ring to move the elevation scale relative to the pressure scale, but it is stuck solid.
Any words of wisdom for me?
