MODEL SR465
FLOOR SCALE SYSTEM
The SR465 is a Precision Digital Scale System specifically designed to be installed
in the floor so that the weighing surface is flush. The multi-purpose design offers the
versatility of being used as a Stand-On scale for weighing ambulatory patients as
well as a Wheelchair / Chair / Walker Scale for semi or non-ambulatory applications.
This Scale System employs the latest in microprocessor and load cell technology
to provide accurate and repeatable weight data. Four (4) identically matched load
cell transducers are strategically placed to ensure an accurate representation of
the patient's weight regardless of weight distribution.
The low power microprocessor circuitry allows the SR465 to derive it's power from six (6) common
"D" cell alkaline batteries which will provide over 20,000 weight reading before needing replacement.
This eliminates the need for an external battery charger or an A.C. outlet.
The Patient's weight is displayed on a user friendly 16 character dot matrix liquid
crystal display. This display uses bright green L.E.D. back lighting for superior visibility
in all lighting conditions. With the push of a button, patient weight may be viewed in
both POUNDS and KILOGRAMS with a displayed resolution of 0.1 #/Kg (100 grams).

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;
1. Press the "O" button. The displayed message will indicate " HANDS OFF ". Make
sure that nothing is in contact with the scale system while zeroing. In a few seconds
the display will indicate "WEIGHT = 0.0 LB ".
Note: When the unit is first turned on the mode will default to the last mode used.
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 to the
scale system. When the "0" button is pressed, the display message will indicate
"HANDS OFF". At this point you should make sure that nothing is in contact with the
weighing surface so that the system zero will be accurate. In a few moments the
display will read - "WEIGHT = 0.0 Lb".
The display mode will automatically default to the last mode used
If after positioning the patient on to the scale system, the display shuts off before
you are able to view the weight data, simply press the "WEIGH" button to WAKE the
display and view the patient's weight.
NOTE: It is recommended that you ZERO the system before each weighing to
assure accuracy.
The "HOLD" button will freeze the displayed patient weight and store it away in
memory. To recall the LAST WEIGHT after the system has shut off, press the
"HOLD" button BEFORE pressing any other. The system only recalls the LAST
WEIGHT that was stored by HOLD.
Weight data may be viewed in either Pounds or Kilograms. Pressing the "MODE"
button allows you to toggle the POUNDS and KILOGRAMS display modes. Both
modes will display a resolution of 0.1 pounds or kilograms.

SYSTEM CALIBRATION and MAINTENANCE S
IMPORTANT : The following calibration procedure should only be performed by qualified
service personnel. The SR465 load cell, itself, has no user serviceable components and should
not be tampered with for any reason. Recalibration is generally not required, but may be checked
periodically to ensure accuracy.
CALIBRATION PROCEDURE :
NOTE: Make sure that nothing is in contact with the scale system during this procedure. Be sure
to remove your hands from the system when noting the displayed calibration results.
1. Press and Hold both buttons simultaneously.
2. The display will read "HOLD TO CAL" as the right hand digit counts down to
enter 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 to
the displayed reading.
5. Use the LEFT CAL button to make "+" corrections and the RIGHT button to
make "-" corrections to the displayed weight. The displayed value should be within
0.1% of the calibrated weight plus or minus 1 digit of reading.
When adjustments are completed:
press the "WEIGH" button to ABORT your changes and exit the CAL mode or
press the "HOLD" button to SAVE all changes and exit the CAL mode.

SYSTEM CARE and CLEANING
CLEANING and DISINFECTING:
The readout housing for the SR465 Scale Systems is primarily made of aluminum. You need
only exercise caution when cleaning the display window of the electronics as this is made of clear
polyester . 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.
BATTERY REPLACEMENT (model SR465 only):
When battery replacement is necessary the display will indicate "REPLACE BATTERY".
To replace the batteries
1.Remove the instruction cover plate to expose the battery compartment..
2.Replace ALL SIX (6) Batteries as shown.
3.Replace the cover plate.

Model SR465 Platform Installation Procedure
NOTE: PIT FRAME OUTSIDE DIMENSIONS- 3" HIGH 38" WIDE 42" LONG
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 described in fig. 1 below.
4.Remove the platform deck by using the 1/4" hex wrench (supplied) to remove the 4mounting 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 (A) 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 you
are planning on tiling or carpeting the deck be sure to compensate for the thickness of material. You may place the deck
on the platform to check the level as you make your adjustments.
9.When the 4 corners are done, adjust the remaining level bolts so that they make contact with the floor of the pit then
back them off a 1/4 turn.
10.When your level adjustments are complete tighten the locking nuts on all 6 level bolts to lock them in place.
11.Adjust the 6 side clearance adjustment bolts (B) so that the platform is spaced equally on all sides of the pit then tighten
the locking nuts on all six (6)bolts.
12.Set the deck on to the platform and secure in place with the 4top mounting screws.
