Default Re: Avometer Movements

My Model D which suffered 7% shortfall needed (only one) Nd disc shaped magnet, it was 10mm diam. and 4mm thickness. This was a meter with the horizontal type horseshoe magnet, there was not a great deal of room for manoeuvre- just enough.

If you have a 12.5% shortfall perhaps one of these either side..? (adjusting them may be tricky, but at least you don't need to glue them in place before testing..)

If i was buying them again i would get an assortment of sizes.

Incidentally I have yet to find a Model 8 or 9 (or indeed anything with later type block magnets) that was beyond adjustment.
