SYSTEM DESCRIPTION and INTENDED USE

SYSTEM DESCRIPTION

The SR575 Bariatric Stand-On Scale employs the latest in microprocessor and load cell technology
to provide accurate and repeatable weight data. Four (4) identically matched transducers are
strategically placed to ensure an accurate representation of the patient’s weight.

The low power microprocessor circuitry allows the SR575 to derive its power from six (6)
common “D” cell batteries, which will provide up to 10,000 weight readings before needing
replacement. This eliminates the need for an external battery charger or the danger of an AC
power supply cord on a portable scale.

The patient’s weight is displayed on a 16-character dot matrix LCD. With a push of a button, weight
data may be viewed in either pounds or kilograms with a displayed resolution of 0.1 for each.

INTENDED USE

The SR575 Bariatric Stand-On Scale is specifically
designed for use as a portable patient weighing system
for ambulatory and non-ambulatory wheelchair bound
patients or those that need to be supported by a chair or
walker. Maximum weight capacity must not exceed
1000 pounds or 454 kilograms gross weight.

BUTTON FUNCTIONS

ZERO

The “ZERO” button is used to zero the system before placing a patient onto the scale
system. When pressed, the display message will indicate “PLEASE WAIT” “HANDS
OFF”. Ensure that nothing is in contact with the scale system during this procedure. The

display will read “WEIGHT 0.0 LB” (or KG).

WEIGH

The “WEIGH” button wakes up the display and shows the patient’s weight if it should
Auto Power Down before the weighing process is done.

HOLD

The “HOLD” button freezes the displayed weight and stores it away in memory. Press
“HOLD” to store the weight into memory. To recall last weight reading, press “HOLD”.

LB/KG MODE

Weight data may be viewed in either pounds or kilograms. Pressing the “LB/KG MODE”
button allows the operator to toggle between the two readings. Both pounds and kilograms

are displayed in a resolution of 0.1.

BASIC SYSTEM OPERATION

SETTING SYSTEM ZERO

Make sure scale is free and clear of any obstructions and press the “ZERO” button. The
displayed message will indicate “PLEASE WAIT” “HANDS OFF”. Ensure that nothing

is in contact with the scale while zeroing the system. In a few seconds, the display will read
“WEIGHT 0.0 LB” (or KG). Note: If patient will be using a cane for support on the scale, place
the cane on the scale while zeroing the system. This will ensure that the patient’s NET weight will
be displayed. It is recommended that the system be zeroed prior to each new patient.

After the scale has been set to zero, position the patient on the scale. The patient’s weight will be
displayed in either pounds or kilograms.

CONTINUOUS WEIGH

In this default mode, the weighing surface remains active. Press the “HOLD” button once to lock
the displayed reading and store it in memory as the “last weight” for recall later.

THEORY OF OPERATION

SR Instruments patient weighing systems are digital scales. Strain-gauge force cells convert the force
of an applied weight into an analog signal. This signal is amplified by an operational amplifier and
converted to a digital signal by an analog to digital converter. The digital signal is transferred to a
micro-controller where it is filtered, converted to appropriate units, and displayed on a liquid crystal
display.

Strain-gauge force cells each contain four strain gauges mounted in a full Wheatstone-bridge
configuration. These bridges convert the physical movement of the force cell, due to the applied mass
on the system, into minute changes in electrical resistance. These changes in resistance produce a
voltage difference across the Wheatstone-bridge, which is amplified by the operational amplifier. The
amplifier is configured to current sum the output of each cell, with potentiometers serving to adjust the
sensitivity (voltage out per unit of weight applied) of each bridge. The offset potentiometer produces a
small current, which nulls the output of the amplifier for an unloaded system.

The output of the operational amplifier is digitized by the analog to digital converter. The converter
integrates the analog signal onto the integrating capacitor over a short interval. The integrating
capacitor is then discharged at a rate proportional to the reference voltage applied to the converter.
The residual voltage on the integrating capacitor is then multiplied by a factor and again discharged at
a rate proportional to the reference voltage. The residual voltage from this discharge is again
multiplied by a factor and again discharged. The time taken to discharge the capacitor is proportional
to the voltage from the operational amplifier, which is proportional to the applied load on the force
cells. The time is stored as a binary number in the analog to digital converter and is transferred to the
micro-controller when the conversion is complete.

The micro-controller averages and filters the digital output of the analog to digital converter, subtracts
the value saved during the system zero operation and scales the filtered output, then displays the result
on the liquid crystal display. The micro-controller performs a rolling average of data for continuous
weigh and, for AutoHold, the micro-controller averages the data before locking in on the reading. If
the data variance is greater than 0.1% in the AutoHold mode, the micro-controller will reset the filter
and start a new averaging period.

The micro-controller can be placed in a calibration mode, where the system can be re-calibrated. In
the calibration mode, the result of the weigh operation is scaled to match the value by adjusting the
“up” and “down” calibration buttons. This new calibration factor is then stored in the non-volatile
memory.

CALIBRATION

IMPORTANT

CALIBRATION CHECK - Qualified service personnel only should perform this
procedure. Load cells have no user serviceable components and should not be tampered
with for any reason. Re-calibration is generally not required, but should be verified
periodically to ensure accuracy. Recommendation for calibration check is at least once
every 12 months, or as individual maintenance policy requires.

HIDDEN CAL BUTTONS

Note: Ensure that nothing is in contact with the scale system during this procedure. Remove

hands from the system when noting the displayed calibration results.

STEP 1: (Figure 5) Simultaneously press and hold the hidden calibration buttons on the label
(“+” and “-”). The display will read “HOLD TO CAL” as the right hand digit counts down from
9 to 0 to enter the CAL mode.

CALIBRATION

STEP 2: When in the CAL mode, press the “ZERO” button to zero
the display.

STEP 3: Place a known calibrated weight, traceable to NIST, onto the
weighing surface and compare it to the displayed reading. Note: DO
NOT USE barbell weights or calibrate to a mechanical scale.

STEP 4: Use the “+” and “-” buttons to make any necessary
adjustments to the displayed value. The displayed value should
be within 0.1% of the calibrated weight, plus or minus 1 digit of
reading.

STEP 5: When adjustments are completed: Press the “HOLD”
button to SAVE the settings, or press the “WEIGH” button to
CANCEL. Both choices will EXIT the CAL mode.
