SYSTEM DESCRIPTION and INTENDED USE

SYSTEM DESCRIPTION

The SRV714 Large Animal Platform Scale employs the latest in microprocessor and load cell

technology to provide accurate and repeatable weight data. Six (6) identically matched Load Cells

are environmentally sealed and strategically placed to ensure an accurate representation of the

subject’s weight.

The SRV714 Large Animal Platform Scale derives its power from six (6) each “D” cell batteries.

Weight is displayed with a displayed resolution of 5 pounds or 2 kilograms.

The SRV714 Large Animal Platform Scale is equipped with a Bluetooth wireless module. By

waking the scale up with the “ZERO / ON”button (located at the end of the Transducer), the

wireless feature is turned on. Then use the free SR Scales app (Google Play store) to connect with

the scale from any Android device to allow for remote wireless operation.

INTENDED USE

The SRV714 Large Animal Platform Scale is designed for use with farm stock, pachyderms,

marine mammals, pinnipeds, and other large animals. It is a preferred means of gathering weight

data up to 15,000 pounds or 6,800 kilograms.

MAINTENANCE and CLEANING

The SRV714 is constructed from durable

stainless and aluminum tube with a high

density anti-slip plastic surface. Exercise

caution when cleaning the high density

plastic surface as it can be scratched by

abrasive cleaners. Waterproof seals can

also be damaged. We recommend mild

soap and water for general cleaning and

disinfecting.

STORAGE and TRANSPORTATION

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

outside the following conditions: Relative Humidity 0% to 85%, Ambient Temperature 14F to

122F (-10C to +50C).

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 Whetstone-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 Whetstone-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 output of the operational amplifier is digitized by the analog to digital converter.

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.

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.
