Chapter 3: Installation 31 of 60 GH Calibration The load cell on a GH Hopper is FACTORY CALIBRATED. Since the load cell can be subject to shock loading during shipping , moving, etc., we recommend that they be recalibrated. The heart of the rate monitor system is the load cell and the supplied calibration weight.
Chapter 3: Installation 32 of 60 Figure 15: Display Calibration Menu Screen 3. Once in “Scale Calibration”, enter in the scale calibration weight value stamped on the side of the weight. 4. The controller will prompt you to em pty the weigh hopper and press “OK”.
Chapter 3: Installation 33 of 60 5. Add the calibration weight to the weigh hopper and write down the value displayed in “weight”, as in step 4. 6. Subtract the values recorded in step 4 from st ep 5. This is the measured weight. If the measured weight is within a 0.
