Full Weight Calibration
When SETTING FULL WEIGHT, BE SURE you know the exact weight (in grams or pounds) that you
are adding to the chamber. Place this weight in the chamber.
Enter the EXACT weight that you have placed in the chamber. Weigh units are in tenths of a pound or
tenths of a kilogram depending on the weigh units set in LOAD Cell Setup menu. The weight should be
close to 200.0 lbs. or 91.0 kilograms.
It is recommended that this weight be measured out in pelletized
plastic beforehand and conveyed to the heating hopper.
After FULL weight calibration, if the display says (BAD CELL), the weight you are using does not match
the weight you entered, the chamber is not free to move, OR the load cells are bad.
Full Weight Calibrations -
Full weight calibration will be done on both the Vacuum Chamber and
Retention Hopper. It is recommended to use a known weight of material for the Full Calibration. Place
approximately 200 lb. of material into the Heating Hopper. Using Manual Operations, Operation
Outputs, Vac Cham Fill, dispense the material from the Heating Hopper to the Vacuum Chamber prior
to entering the Full Calibration Routine.
If material totals are being observed loadcell full weigh calibration is recommended every 6 months.
The ZERO point of the load cells is now set properly. FULL weight calibration may also be done at this
time, however, it probably is NOT NECESSARY. When load cell readings shift due to rough handling,
the entire range of readings from ZERO to FULL shift together. The ZERO weight calibration routine
resets the full range of the cells and, therefore, corrects FULL weight readings as well.

Display will say: Confirm Vacuum Chamber is empty then press
ZERO. Gram weight of 0 follows successful calibration.
Press

Display will show a keypad and the message: Enter the known weight
and then press ENTER. Enter your known weight in GRAMS and then
press ENTER.
Place the known weight in the Vacuum Chamber and then properly re-install the Vacuum Chamber into the Dryer.
Press CONTINUE to proceed.
Wait while calibrating load cells. Do not touch weigh bin during calibration. After Full calibration has proceeded
successfully, you will be prompted.
Press
