(1) Hardware Pack, containing:
(2) Screws and Plastic Wall Anchors
(4) Non-skid Scale Feet
Install the Scale Feet
IMPORTANT! THE LEVELING FEET MUST BE INSTALLED TO OPERATE
THE SCALE.
1. Remove the four leveling feet from the
shipping pack and install one in each
corner of the bottom of the scale base
assembly.
2. For best results, place the scale on a flat
level surface and adjust the leveling feet
to ensure the scale is sitting level and

SETUP AND INSTALLATION, CONT.
Transporting the Scale
The VET550 has built-in wheels and an integral carrying handle
for easy transportation of the scale to a new location. Follow the
instructions below to safely lower and raise the scale to and from
the floor when relocating the scale.
DO NOT DROP THE SCALE! This scale weighs
approximately 40 pounds. Damage to the load cells can
occur if the scale is dropped or allowed to fall from the
transport position. If damage to the scale is determined
to have been caused by falling or dropping the scale,
the warranty will be voided!
Lowering Scale from Transport Position to Floor
1. From the transport position, stand close to the scale with your
feet 8 to 12 inches apart.
2. Firmly grasp the handle on the scale.
3. While stepping back, lower the scale to the floor, keeping your
back straight and bending your knees until you are in a
squatting position.
Never bend at the waist with your legs straight!
Lifting Scale from Floor to Transport Position
1. Stand close to the scale with your feet 8 to 12 inches apart.
2. Keeping your back straight, bend your knees until you are in a
squatting position.
Never bend at the waist with your legs straight!
3. Firmly grasp the handle on the scale and lift it straight up. Do
not twist to either side. Keep the scale close to you, not at
arm's length.
4. Use your leg muscles as you lift, keeping your back upright and in its natural posture.
Always lift steadily and smoothly without jerking.
Storing the Scale
For storage, lay the scale flat for maximum protection against damage.
Placing the Scale
The scale should be placed on a flat, level floor or low-cut carpet away from any rapidly
moving air source (heating and cooling vents). Check to make certain the scale is level and
does not teeter. If it is not, adjust all four (4) feet as required to attain a level scale.
NOTE: Any time the scale is moved or re-located, be sure to check if the scale is
level before using it.

SETUP AND INSTALLATION, CONT.
Placing the Weight Display
The VET550 display has a 7.0 ft (2.1 m) cable to allow it to be placed at a convenient position
away from the scale base. The included bracket can be used to mount the weight display on a
wall for easy viewing and operation.
Wall Mounting the Weight Display

on the wall where it can be easily viewed,
not subject to direct sunlight, and where
the keypad is within easy reach of the
operator.
2. Using the bracket for a template, place the
bracket against the wall and mark the
holes to drill.
3. Remove the bracket and drill two holes in
the wall for the mounting wall anchors.
4. Insert the two wall anchors into the drilled
holes and push them in until they are flush
with the wall.
5. Place the weight display bracket against
the wall aligning the holes in the bracket
with the two wall anchors and insert the
two (2) wall anchor screws through the
bracket and into the wall anchors.
6. Tighten the screws to secure the bracket to the wall.
7. Plug the display cable into the bottom of the weight display and then set the weight display
on the bracket.
Interconnections
Power and output connections to the VET550 Digital Veterinary Scale are made on the right
side (as viewed facing the display) of the weight display. Connections for the scale input are
made using a snap-in modular connector on the bottom of the weight display. The USB port is
a device (or upstream) port using an industry-standard “B” connector. The included 15V DC
wall plug-in UL/CSA listed AC power adapter is connected using a power jack.
AC Power Adapter
To apply power to the VET550 scale using the
supplied 100 to 240V AC 15V DC 300 mA wall
plug-in UL/CUL listed AC power adapter,
insert the plug from the power adapter cable
into the power jack on the right side of the
display and then plug AC power adapter into
the proper electrical outlet.
Use the weight display mounting bracket
as a template to mark the holes to drill.

PRINT OUTPUT SETTING DATA FORMAT
The VET550 Digital Veterinary Scale weight display USB port can be connected to a computer
for transmission of weight data to an EMR (electronic medical record) software program. The
VET550 can be configured to transmit the weight data continuously (when the weight
becomes stable) or one time when receiving a weight request “P” (50h) or “p” (70h) from the
host computer. This is known as Weight-On-Demand. Examples and explanations of the data
format transmitted are shown below.
xIf
<&6 is selected for $*& (Print Output Setting), the scale will transmit the weight
data continuously when the weight becomes stable.
xIf
# was selected for $*& (Print Output Setting), the scale will transmit weight data
one time when receiving a weight request “P” (50h) or “p” (70h) from the host computer.
When the weight is stable or the scale receives a “P” (50h) or “p” (70h) command:
The scale will respond with the following 31-byte weight strings:
