Remove the top cover and locate the indicator at the center of the front of the scale base. FIG.
Hardy Bench Scales Step 2. To level the platform, turn the leveling feet clockwise to lower the scale corner, or counter clockwise to raise it until you show a level reading by centering the bubble in the center of the indicator. Leveling Foot 4 Places FIG. 3-2 LEVELING FEET Scale Connections 3-4 To connect the scale, you must first remove the cover, unroll the cable and run the cable through the hole in the back of the unit. Replace the cover.

Chapter 4 - Calibration CHAPTER 4 - CALIBRATION About Calibration of the Hardy Bench Scale The Hardy Bench Scales come calibrated from the factory. Make sure the scale is correctly wired to the weighing instrument or indicator. Refer to the weighing instrument or indicator manual for calibration instructions. C2 Second Generation Calibration C2 electronically calibrates a scale system without the need for test weights.
Chapter 5- Troubleshooting CHAPTER 5- TROUBLESHOOTING SCOPE All the information in Chapter 5 pertains to the troubleshooting and resolution of operating problems that may occur. All maintenance personnel and users should be familiar with both Chapters 3 and 4 before attempting to troubleshoot problems with the Scale. Problem: Scale Does Not Respond When Weight is Applied Step 1. Step 2. Step 3. Scale Indication is not linear Step 1. Step 2. Step 3. Step 4.
Hardy Bench Scales Step 2. Step 3. Step 4. Step 5. Step 6. Service and Repair (All Models) Make sure the corner mechanical overload stops are not engaged with the platform. Lower as necessary. Verify that the instrument or network is operating properly. Make sure there are no high voltage wires close to the scale. Check that the scale and instrument are properly grounded. If high static electricity is present a ground strap should be added from the top cover to the chassis and to earth ground.
