DETECTO 6560 Portable Wheelchair Scale

PORTABLE WHEELCHAIR SCALE  TEST PROCEDURE

• A. Equipment Required
  B. Scale Trim Adjustment
  C. Calibration
  D. Final Test

Equipment Required

• Scale under test
• Standard Hand tools
• Test Weights: Certified weights to accomplish the linearity tests

Scale Trim Adjustment

1. Gain access to the junction box and remove the cover.
2. Place a test weight of at least 25 percent of scale capacity on each corner, one at a time, and record each displayed weight.
3. Place test weight on the corner with the highest displayed weight and adjust appropriate trim potentiometer counterclockwise until corner reading agrees with the lowest weight reading.
4. Repeat Step No. 3 until all corners are within tolerance. For tolerance values, refer to the Linearity Check Table in the D. Final Test section.
5. If any trim pot reaches the end of adjustment in the CCW direction then turn all potentiometers clockwise 25 turns or until a click is heard. Now turn all potentiometers counterclockwise 1 (one) turn and repeat steps 2 – 4.
6. Turn the power off.

Calibration

1. To begin Calibration and Setup, make sure the MEDVUE indicator is turned on.
2. Next, looking at the front of the MEDVUE, remove the two screws from the left end cap and remove the end cap.
3. Locate the calibration switch access hole near the bottom of the side panel, and insert a small hex wrench or tool through the access hole.
4. Press and hold the calibration switch until the display changes to show SETUP in large letters at the top of the display, and SCALE in smaller letters at the bottom.
5. Release the calibration switch. You are now ready to perform calibration.
6. During setup and calibration, pressing the PRINT/ENTER key will cause the data displayed, to be retained and the indicator to advance to the next prompt. Change the value by entering the new data using the numeric keypad, and then pressing the PRINT/ENTER key.
7. Follow the prompts listed in the MEDVUE SETUP TABLE.

Final Test

1. Perform Corner Test using 1/4 capacity weights (positions 1-4). Use tolerances listed in the table below.
2. Perform the Linearity test. Check both ascending and descending. See the table below.
3. Install indicator cover.

Linearity Check Table

APPLICATION OF ADHESIVE/ADHESIVE-BACKED ITEMS

1. Use a clean cloth or paper towel to clean the surface with alcohol where the adhesive or adhesive-backed item is to be applied.
2. After the alcohol has dried, use another clean dry cloth or paper towel to wipe the surface clean of all residue before the adhesive-backed item is applied.
3. Apply the adhesive-backed item immediately after the surface has dried. Be careful not to touch either the application surface or the adhesive with the bare hand.
4. Using a clean dry cloth or paper towel, rub out all air bubbles on flat items, such as keypads, labels, serial tags, etc., by rubbing back and forth on the surface of the adhesive-backed item while pressing firmly.
   NOTE: Be sure to press firmly on each corner to ensure a good bond.
5. For items that have foam tape, such as standoffs, apply the items straight to the surface and hold in place with firm pressure for 5-10 seconds.
   NOTE: Most adhesive-backed items will not attain full strength until after 24 hours. The above procedure must be followed to obtain the maximum bonding strength of any adhesive.

PARTS IDENTIFICATION

Final Assembly – 0065-0680-0A

NOTES:

1. Wire indicator and load cell cables as shown in the schematic. Check to make sure that none of the indicator cables or load cell cable wires are crossed, or touching where they connect to the trim board to avoid a short circuit. Route cables through available holes.
2. Self-tapping screw (item 6) fastens handrail weldment (item 4) to scale. 2 ea. Self-tapping screws (item 6) are used per column (items 2 and 3).

6560/6570 Universal Base Assembly – 0065-0703-0A

NOTES:

1. Center and apply deck mat (item 22) and ramp mat (item 23) on top of the deck (item 1) and ramps (item 6) before assembly.
2. HR BTTM base/dual-column (item 3) must be attached to the deck (item 1) before the installation of load cells (item 4).
3. Apply Loctite (6560-1126) to threads of the bolt before installation.
4. Ramps can be attached for alignment and positioning of load cells. Ramps will be removed with rubber mounts (item 5) left installed in load cells for calibration and packaging.
5. When installing screws (item 10) into rubber mounts (item 5) for alignment purposes, be careful not to overtighten as this may shear the rubber mount.
6. Ensure that screws (item10) are set aside for individual packaging.
7. Ensure all wiring is routed to the trim board through available holes in stiffeners.
8. Tighten load cell bolts (item 8) to 35 ft-lbs.
9. Tighten screws (item 21) until snug and PCB is held firmly in place. Do not overtighten for the risk of crushing PCB.

CARE AND CLEANING

Indicator
The indicator contains no user-serviceable parts and maintenance should be limited to an occasional cleaning and battery replacement as required.

General Cleaning Instructions

• Do not submerge the scale or indicator in water, pour, or spray water directly on them to clean. The scale and indicator are not waterproof and covering them with water will damage them and void the warranty.
• Always remove power before cleaning.
• When cleaning, use only damp soft cloths or plastic scouring pads for cleaning cloth and a mild non-abrasive detergent.
• DO NOT use acetone, thinner, or other volatile solvents for cleaning.
• DO NOT use things that will scratch the surface, such as steel pads, wire brushes, and scrapers.

Powder Painted Steel Care and Cleaning
While powder-painted steel is attractive and so durable that it will last many years longer than ordinary painted steel, it is desirable to clean it thoroughly on a routine basis. Three basic things should be remembered when cleaning powder-painted steel.

1. Do not use wire brushes, abrasives, or cleaning tools such as steel pads and scrapers, which will scratch the painted surface. Instead, use soft cloths or plastic scouring pads for cleaning. Clean food equipment frequently to avoid build-up.
2. When possible, use treated water. Hard water can leave behind deposits. Soft water is much gentler on the painted steel’s surface.
3. Avoid the use of acetone, thinner or other volatile solvents, and abrasive type cleaners for cleaning. If required, a mild solvent such as mineral spirits can be used to remove oil, grease, tars, wax, and similar substances. Use a cloth dampened with mineral spirits and apply only to areas that are contaminated. Follow up the use of this mild solvent with detergent cleaning and rinsing.
