Weigh the collected granules. If the actual weight is not 200 lbs, perform the
following calculation:

EXAMPLE:
EXAMPLE:
Old GRAN CAL
= 200
GRAN TOTAL reading
= 200
Weight of collected material
= 128
Corrected GRAN CAL
= Old GRAN CAL x GRAN TOTAL reading
Weight of collected material
= 200 x 200 = 312
128
Corrected GRAN CAL = 312
This is the new GRAN CAL value.
Enter this corrected GRAN CAL into key labelled:
Repeat this procedure (starting with
Step 3
) until the weight of the metered
material equals the value in the GRAN TOTAL display.
