Lyman M-1000 and Pro 1000 Scales
M-1000 and Pro 1000 Scales
The M-1000 and Pro 1000 scale has a capacity of 1005 grains; 1000 from the large poise
scale, when the 500 counterweight is placed on a special pin located at the extreme left end of
the beam, and five grains from the small poise scale. Before using this feature, be certain the
scale has been properly zeroed (see Zeroing). With the 500 counterweight in place on the pin,
add 500 grains to the actual scale readings. Please note that the 500 counterweight does not
weigh 500 grains.
Model 500 Metric Scale
The Model 500 Metric scale has a capacity of 32.75 grams, 32.50 from the large poise scale
and .25 from the small poise scale. It is accurate to plus or minus .005 gram and has been
carefully calibrated at the factory. Measurements on the small poise scale represent grams
from 0- .25 marked in .005 gram increments. Measurements on the large poise scale run from
0-32.50 grams marked in .25 increments.
Reading the Measurements on the Pro 500, M-500 (D-7) or M-1000 and
Pro 1000 Scales
To read the measurement, first look at the large poise scale. If, for instance, the poise is
directly over the 100 mark, you will know that it is reading 100 grains. If it is one scribe mark
to the left, the reading will be 105 grains; two scribe marks to left, and the reading will be 110
grains, etc. To this measurement you must add the reading from the small poise scale. If, for
instance, the small poise is positioned over the one and the large poise is over 100, the read-
ing will be 101 (add the small poise scale reading to the large poise scale reading for your
total measurement). If the large poise scale reads 105 grains and the small poise scale reads
2.2 grains, you know the total measurement is 107.2 grains.
