Photo 17: Main poise set on zero
To increase weight values, move the poise to the left and line up the indicator with
the desired graduation. Always make sure the pawl is seated in the notch. For
example, the correct setting for 160 grains is shown below (Photo 18).
Photo 18: Main poise set at 160 grains
Do not attempt to set the main poise at any position except firmly seated in a notch.
Always use the medium poise for weight values (0-20) and the small poise for weight
values (0-1) between the 20 grain increments of the large poise.
hOW TO USE ThE MEDIUM POISE (20 GRAIN)
The medium poise functions the same as the large poise. This poise run is from 0 to
20 grains and the equally spaced notches divide this distance into 20 equal parts so
that each subdivision is equivalent to 1.0 grain of weight.
To zero the medium poise, move it to the position where the pawl, which is the top
edge of the rectangular slot through the poise, engages the notch directly above the
"0" graduation. The long, vertical edge of the poise is the indicator and will line up
with the"0" graduation.
To increase weight values, move the poise and line it up with the desired graduation.
Always make sure the pawl is seated in the notch. For example, the correct
setting for 14.0 grains is shown above (Photo 19). Do not attempt to set the poise at
any position, only set in a position where it is firmly seated in a notch.
