Part # Description

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.

MAINTENANCE and CLEANING

The display case for the SR575 Bariatric Stand-On
Scale is made of a powder-coated aluminum casting.
Exercise caution when cleaning the display window as
it is made of clear polyester and can be scratched by
abrasive cleaners. Mild soap and water is recommended
for general cleaning and disinfecting.

DO NOT use pressurized water or
steam. The scale system contains
microprocessor circuitry and strain

e sensors that may be adversel
affected by exposure to such an
environment.

WARNING

STORAGE and TRANSPORTATION

STORAGE

If storing this equipment for periods longer than three (3) months, remove the batteries. To
maintain proper operation of this instrumentation, storage and transport conditions should not vary
