1. SYSTEM DESCRIPTION and INTENDED USE SYSTEM DESCRIPTION The SR725i SR725i L Wheelchair 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 SR725i7 SR725i L to derive its power from six 6 common D cell batteries which will provide up to 400 hours of 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 The weight data may be viewed in either pounds or kilograms with a displayed resolution of 0 1 for each INTENDED USE The SR7251 SR725i L Wheelchair Scale is specifically designed for use as a portable patient WARNING weighing system for ambulatory and non ambulatory DO NOT EXCEED wheelchair bound patients Maximum weight capacity MAXIMUM WEIGHT LIMIT OF must not exceed 1000 pounds or 454 kilograms gross 1000 LB 454 KG weight MAINTENANCE and CLEANING The display case for the SR725i SR725i L Wheelchair Scale is made of a powder coated aluminum Exercise WARNING caution when cleaning the display window as it is made DO NOT use pressurized water or of clear polyester and can be scratched by abrasive2.

16. l 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 normalize 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 sigma delta converter sums a rapid sequence of O s O volts and 1 s reference voltage to achieve balance with the input signal from the amplifier The micro controller filters the digital output of the analog to digital converter subtracts the value saved during the system zero operation and scales the filtered output and then displays the result on the liquid crystal display The micro controller performs a moving median filter of data for continuous weigh and for AutoHold the micro controller performs checks for signal stability 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 filtering period The micro controller can be placed in a calibration mode where the system can be re calibrated In the calibration mode the system slope is calculated from two points zero and full scale in the 2 point calibration
