To determine the Glass Total Meter calibration number for any glass yield
not given in charts E and F calculate the calibration number as the example
below.
VRC-2000-XXX, Pro Chopper and 4 Strand Chopper assemblies (70020-X)
Example: Yield 205 yds / lbs
Rotor circumference:

VRC-2000-XXX, Pro Chopper and 4 Strand choppers (70020-X) = 3.7699 in.

6 Strand Chopper Assembly (70010-1) = 5.4035 in.
1. Multiply yield number by 36 (inches in a yard).
205 yds 36 in
1 lbs 1 yd
2. Divide the circumference of the chopper rotor in inches by the glass
yield in inches.
3.7699 in 7380 in
1 rev 1 lb
3. Multiply the number of strands by the result of step 2.
1 x .0005108 lbs / rev = .0005108 lbs / rev
4. Divide the result of step 3 by 2 (the number of pulses per revolution) to
get the number of pounds per pulse.
.0005108 lbs 2 Pulses
1 rev 1 rev
5. Now multiply the result of step 4 by 10 to account for the one place
decimal in the display.
.0002554 lbs / pulse x 10 = .002554 lbs / 10 pulses
This corresponds with the chart for 1 strand of 205 yield glass through a
VRC-2000-XXX, Pro Chopper and 4 Strand Chopper (70020-X).
x = 7380 in / lb
x
= .00005108 lbs / rev
x = .002554 lbs / pulse
