ASSEMBLY
ASSEMBLY STEPS
STEP1: Unpack Large Animal Platform Scale (1) and check parts against PACKING CHECKLIST.
If there are any missing or damaged parts, call Service Hotline at: 1-800-654-6360.
STEP 2: Remove the center panel to access the Display Housing (see Figure 4). Unplug the two (2)
transducer cables that come from the display box. Unscrew the four (4) screws from the
plastic cover on the display housing. Loosen the two thumb screws on the battery holder
cover and remove the cover. Install the six (6) “D” cell batteries according to battery holder
imprinted instructions. Attach the battery holder cover and tighten the thumb screws. Re-
secure the plastic cover with the four (4) screws.
STEP 3: Remove the other two end panels from the Transducers.
STEP 4: Place one (1) load cell spacer (metal ring) over the threaded stud of each of the six (6) load
cells. Then thread on one (1) rubber foot on each of the threaded studs (Figure 1).
STEP5: Place the two (2) Transducers, with the adjustable stainless feet resting on the floor, parallel
to each other and approximatelyfour (4) feet apart (Figure 2).
STEP 6: Align one of the end panels (without electronics) with the alignment pins at either end
of the transducer tubes. Carefully slide the panel down onto the alignment pins in the
transducer tubes. Ensure that the panel is sitting flat on the tubes and all four (4)
alignment pins are engaged. Repeat this step for the opposite end (Figure 3).

ASSEMBLY (CON’T)
STEP 7: Carefully place the center panel with electronics on an angle on top of one of the
previously assembled panels and one (1) transducer tube. When stable, plug in the two
(2) transducer cables that come from the display box under the center panel to each of
the transducer tubes. Ensure that the transducer cables are in line with the connectors
on the transducer tubes (Figure 4).
STEP 8: After the transducers are plugged in, carefully align the center panel with the four (4)
alignment pins that are located in the center of the transducer tubes and slide it down
over the remaining transducer assembly pins (Figure 5).
NOTE: Ensure all adjustable stainless steel feet are in contact with the floor, that the scale is
level and does not rock or twist.
NOTE: If the scale is going to be set up in the same location repeatedly, it may be helpful to
outline the feet of the scale after the scale is fully assembled to assist with placement of the
transducer tubes in the future.

REPLACEMENT PARTS and ACCESSORIES
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.

BASIC SYSTEM OPERATION
NOTE: Ensure that the scale is free and clear of any obstructions before operating.
STEP 1: Turn the scale on. There is a “ZERO/ON” button located at the end of one Transducer
tube.
STEP 2: Scan for Bluetooth devices on your Android device (or the tablet provided with the
scale). Then locate the SRV714 Bluetooth module in the list of devices. The Bluetooth
ID starts with “RNBT-” followed by 4 digits (also listed on the Calibration Form).
Select the appropriate device and pair.
STEP 3: Open the SR Scales app (download free from the Google Play Store) on any supported
Android device (or the tablet provided with the scale) to allow for remote wireless
operation (Figure 6A).
STEP 4: Click on the three dots in the upper right corner of the SR App and select to “Connect a
device” (Figure 6B).
STEP 5: Select the SRV714 Bluetooth module from list of devices (Figure 6C). If the device is
not listed, the display may have turned off or it may not have properly paired. Pressing
the “Scan for devices” button on the bottom of the screen may also refresh the list.
STEP 6: When the device is connected, a weight value will show in the “Real Time Weight”
area. Ensure that the Android Device is communicating with the scale by placing a load
on scale and verifying the reading in “Real Time Weight” area of the SR Scales App.
NOTE: The display will automatically shut down after ten (10) minutes of non-use. If the scale
becomes “Disconnected” from the Android device you must remove the animal from the weight
platform and press the “ZERO/ON” button located at the end of one transducer tube. After doing
so, you can reconnect your Android device. Assist the animal onto the scale platform and its
weight will appear on the display.
It is recommended that the system be zeroed prior to each subject being weighed.
