Gravimetric Batch Blenders w/Mitsubishi Control Chapter 3: Installation 46
ensure that the reported inventory totals are accurate. Remember that in most
cases a bad calibration is worse than no calibration.
Standard Calibration on a blender equipped with an OptiMix style mixer
(Recommended only if the calibration is out of spec)
1. From the “Recipe” Page, touch the Manufacturer’s icon and enter “5413”, then press
the “Enter˝ key.
2. Touch “Calibration” and then “Scale Calibration”.
3. Remove the weigh hopper, clean it out and press “OK”.
4. Verify that the calibration weights are not touching anything other than the load cell
bracket.
5. Enter the number stamped on the calibration weight. Follow the on-screen
instructions by touching “OK” and then follow the prompts.
6. The blender will evaluate the calibration and indicate if it is properly calibrated.
7. Press “Done” key three (3) times and you will return to the main menu.
Standard Calibration on a blender with an HC style mixer (Recommended only if
calibration is out of spec)
1. From the “Recipe” Page, touch the Manufacturer’s icon and enter “5413”, then press
the “Enter˝ key.
2. Touch “Calibration” and then “Scale Calibration”.
3. Empty the hopper and press “OK”.
4. Place the test weight on the hopper and press “OK”.
5. The controller will communicate whether the calibration was successful.
Verifying Calibration (Recommended on a periodic basis to ensure accuracy)
1. From the “Recipe” Page, touch the Manufacturer’s icon and enter “5413”, then press
the “Enter” key.
2. Touch “Calibration” and then “Direct Scale Readout”.
3. Remove the weigh hopper.
4. Locate the weight display for each of the two load cells (or one load cell in the case
of an Auger blender with an “HC” style mixer), directly below “Current Bits.” 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 for clean out.)
7. Press “Done” until you have reached the Recipe screen.
