SYSTEM DESCRIPTION and INTENDED USE
SYSTEM DESCRIPTION
The SR555 Stand-On Scale System 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 SR555 to derive its power from six (6)
common “C” cell batteries that 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 SR555 Stand-On Scale System is specifically
designed for use as a stand-on scale for weighing
ambulatory patients. Optional equipment includes a
Handrail Set and Height Bar. SR555 Stand-On Scale
System is a preferred means of gathering patient weight
data of ambulatory patients weighing up to 1000
pounds or 454 kilograms.
MAINTENANCE and CLEANING
SR555 Stand-On Scale System is made of
powder-coated aluminum casting with
stainless steel riser posts. 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 gauge sensors that may
be adversely affected by exposure to such an
environment.
DO NOT EXCEED
MAXIMUM WEIGHT LIMIT OF
1000 LB / 454 KG
