Press: the button to move to Continue.
Press: ENTER to start the ZERO Calibration.
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.
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 35.0 lbs or 16.0 kilograms.
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 35 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 periodically
(approximately every six months).
