hOW TO USE ThE MAIN POISE (500 GRAIN)

The main poise consists of an accurately adjusted weight that moves parallel to the
axis of the beam. It is positioned at weight values by means of a pawl that engages
notches in the beam. The poise run is from 0 to 500 grains, with equally-spaced
notches that divide this distance into 100 equal parts. Each subdivision is equivalent
to 5 grains of weight.
To zero the main poise, move it to the position where the pawl, located on the right
side of the poise, engages the first notch on the right end of the poise travel. The
poise indicator will line up with the "0" graduation (Photo 17).
