Verify Weigh Hopper (Load Cell) Calibration
Verifying Calibration (Recommended on a periodic basis to ensure accuracy)
1. The blender must be stopped before this can be done.
2. From the Setup Menu touch “Calibration” and then “Direct Scale Readout”.
3. Remove the weigh hopper.
4. Locate the weight display for each of the two load cells. Write down the displayed
value.
5. Add the calibration weight to each load cell mounting bracket and write down the
value displayed in “weight”, as in step 4.
6. Subtract the values recorded in step 4 from step 5. This is the measured weight. If
the measured weight is within a 0.003 pounds of the weight stamped on the
calibration weight, then you are within spec. If not, follow the steps above to
calibrate the blender. (If your blender is frequently out of calibration, verify the
operator is being cautious removing the weigh hopper during clean out.)
7. Press “X” until you have reached the Recipe screen.
