Hardy Process Solutions Weight Controller HI4050PMWS

Traditional Calibration Procedure

Ensure all live load weight is removed from the scale

Place certified test weight on the scale

Is the front panel display lit?

Does the display show a value indicating readiness for calibration?

Load Cell/Point Input/Output Measurements

Measure the mVDC output at full weight capacity for a 2 mV/V load cell/point

Measure the mVDC output at 750 pounds for a 2 mV/V load cell/point

Measure the mVDC output at 500 pounds for a 2 mV/V load cell/point

Zero Reference Point Verification

Measure the zero reference point mVDC output

Place a load on the scale or vessel

Check if the weight reading changes in the proper direction

If the display reading is incorrect, refer to Chapter 8, Troubleshooting

Remove the weight if the display changes correctly and proceed to calibrate the Weight Controller

Load Cell Installation Verification

Ensure no binding on the load cell or other system parts

Visually inspect for objects binding the load cell

Ensure nothing is draped over the scale/vessel or load cell

Verify only service wires and properly mounted flexible connectors contact the scale/vessel

Ensure all pre-calibration procedures are completed

Configure the HI 4050 Weight Controller (units, decimal point, scale capacity, averages, etc.)

Reference Weight and Gravity Correction

Enter the Reference Weight for your application

Enter the Gravity Correction Factor (optional)
