MODEL SR463FLOOR SCALE SYSTEM

The SR463 is a Precision Digital Scale System specifically designed to be installedin the floor so that the weighing surface is flush. The multi-purpose design offers theversatility of being used as a Stand-On scale for weighing ambulatory patients aswell as a Wheelchair / Chair / Walker Scale for semi or non-ambulatory applications.

This Scale System employs the latest in microprocessor and load cell technologyto provide accurate and repeatable weight data. Four (4) identically matched loadcell transducers are strategically placed to ensure an accurate representation ofthe patient's weight regardless of weight distribution.

The SR463 uses 110v A.C. line power and is mounted in a recessed wall box sothe display is flush with the wall.

The Patient's weight is displayed on a user friendly 16 character dot matrix liquidcrystal display. This display uses bright green L.E.D. back lighting for superior visibilityin all lighting conditions. With the push of a button, patient weight may be viewed inboth POUNDS and KILOGRAMS with a displayed resolution of 0.1 #/Kg (100 grams).

MODEL SR463 FLOOR SCALE SYSTEM OPERATION

INITIALIZING THE SYSTEM ZERO:Before the patient is positioned on to the scale system you must first set the system zero.This is done as follows;

Make sure that nothing is in contact with the weighing surface so that the systemzero will be accurate. Press the "O" button. The display will indicate "HANDS OFF -PLEASE WAIT" . In a few moments the display will read - "WEIGHT = 0.0 Lb".

The patient may now be positioned on to the weighing surface

to view the weight data.

BUTTON FUNCTIONS :The "0" button is used to initialize the system zero before placing a patient on tothe scale system. Make sure that nothing is in contact with the weighing surface sothat the system zero will be accurate. Press the "O" button. The display will indicate"HANDS OFF - PLEASE WAIT" .

In a few moments the display will read - "WEIGHT = 0.0 Lb".

NOTE: When the system ZERO is reset, the LAST WEIGHT memory is also reset to zero.

If after positioning the patient on to the scale system, the display shuts off beforeyou are able to view the weight data, simply press the "WEIGH" button to WAKEthe display and view the patient's weight.

NOTE: It is recommended that you ZERO the system before each weighing to assureoptimum accuracy.

The "HOLD / RECALL" button is used to view the STORE and RECALL the lastweight stored in memory. To STORE the current weight, press the "HOLD /RECALL" . After the system has shut of you may press the "HOLD / RECALL"

button view the last stored weight.

Weight data may be viewed in either Pounds or Kilograms. Pressing the "DISPLAYMODE" button allows you to toggle the Lb and Kg display modes. Both modes willdisplay a resolution of 0.1 Lb or Kg.

Note: When the unit is first turned on the mode will default to the last mode used.

SYSTEM CALIBRATION and MAINTENANCE SIMPORTANT : The following calibration procedure should only be performed by qualifiedservice personnel. The load cell, itself, has no user serviceable components and should not betampered with for any reason. Recalibration is generally not required, but may be checkedperiodically to ensure accuracy.

CALIBRATION PROCEDURE :

NOTE: Make sure that nothing is in contact with the scale system during this procedure. Be sureto remove your hands from the system when noting the displayed calibration results.

1. Press and Hold the two hidden "+" and "-" buttons above the zero button.2. The display will read "HOLD TO CAL" as the right hand digit counts down toenter the CAL MODE.3. When in the CAL MODE, press the "ZERO" button to zero the display.4. Place a known calibrated weight on to the weighing surface and compare it tothe displayed reading.5. Use the hidden "ADJUST" buttons to make "+" (left) and "-" (right) correctionsto the displayed weight. The displayed value should be within 0.1% of the calibratedweight plus or minus 1 digit of reading.

When adjustments are completed:Press the hidden "WEIGH" button to ABORT your changes and exit the CAL mode.

----- OR -----Press the "HOLD / RECALL" button to SAVE all changes and exit the CAL mode.

SYSTEM CARE and CLEANINGCLEANING and DISINFECTING:

The readout housing for the SR463 Scale Systems is primarily made of aluminum. You needonly exercise caution when cleaning the display window of the electronics as this is made of clearpolyester . We recommend mild soap and water for general cleaning.

The floor transducer is covered by a Stainless Steel plate and may be vacuumed or swept.

Model SR463 Platform Installation Procedure

1. Carefully unpackage the scale platform and inspect to ensure there has been no shipping damage.2. Prepare the pit area to accept the scale platform and readout as described in fig. 1, below. 3. Mount the readout on the wall and run the connector cable down the conduit to the pit as shown below.4. Remove the platform deck by using the 1/4" hex wrench (supplied) to remove the 4 mounting screws on the cover.5. Place the platform into the pit so that the connector for the readout cable is nearest to the conduit.6. Plug the readout cable into the connector on the platform.7. Position the platform in the pit so that the frame is equally spaced from all sides of the pit.8. Using a 9/16" socket wrench, adjust the 4 corner leveler bolts so that the platform base is one inch (1") below the

surface of the floor on all sides. This will ensure that the deck is even with the floor surface when installed. NOTE: If youare planning on tiling or carpeting the deck be sure to compensate for the thickness of material. You may place the deckon the platform to check the level as you make your adjustments.

9. When your level adjustments are complete tighten the locking nuts on all 4 level bolts to lock them in place.10. Adjust the 8 side clearance adjustment bolts so that the platform is spaced equally on all sides of the pit then tighten the

locking nuts on all eight (8)bolts.11. Set the deck on to the platform and secure in place with the 4 top mounting screws.
