Rice Lake Low Profile Floor Scale HP-H

Refer to the indicator manual for correct calibration procedures.

Exercise the scale by loading it to near capacity two or three times.

Ensure no load is on the scale.

Place the indicator in its calibration mode.

Identify the correct load cell terminal for each corner (CELL 1, CELL 2, etc.)

Refer to Figure 4-4 on page 15 for scale deck corner numbering

Connect and approximately calibrate the indicator

Enter the test weight (25% of scale capacity)

Zero the indicator with no weight on the scale

Ensure all tools are available (pry bar, spirit level, Teflon tape or Loctite if needed)

Verify that the scale is clean and free of debris

Adjust each scale foot by hand until all feet contact the floor equally

Ensure no scale foot is bottoming out against the underside of the load cell

Check that foot stems are not extended beyond the maximum height adjustment

Choose method to secure scale feet if required

Lift scale with chains and proper spreader bar

Remove foot and defective load cell

Disconnect load cell cable from junction box

Cut cable ties and free the cable

Pull cable out of the scale frame channels

For Canadian HC models, loosen overload stops two full turns before installing new load cells

Place a weight equal to 25% of the load cell capacity on the affected scale corner for overload stop reset

Ensure the scale is turned off before cleaning

Verify that the load cells are hermetically sealed

Clean the space between the platform side and pit frame

Clean the surface beneath the platform

Use care with high pressure steam wash downs for hermetically-sealed load cells

Check for any debris build-up after cleaning
