3.6 Calibration
All feeders must be calibrated before any blending recipes can run using the Digital Dosing
additive feeder.
NOTE: The calibration weight (metered material weight for one revolution of the dosing disc) must be determined separately for each material to be dosed since calibration weight differs from material to material.
The following equipment is needed for calculating the calibration weight:
•Scale with a minimum accuracy of 0.01 grams
•The weighing container which is included in the equipment delivery Follow these procedures:
1.Remove one of the square covers and insert the calibration container provided.
2.Fill the dosing hopper with a minimum of six (6) inches of material.
3.Note weight of weighing container (= tare weight) or tare scale to zero
NOTE: The Digital Dosing station may only be operated if all sample chutes are in place or a collecting bin is in the calibration box.
Determining the Calibration Weight
Step 1:
•To start the calibration process, press the calibration key.
Step 2:
•Once the sample container is in position, press 
.
•The disc will rotate 1/4 revolution and dispense material into the sample container. After the disc stops, the screen will remain blank.
