INTRODUCTION
Thank you for purchasing our Detecto 7550 Wall-Mount Fold-Up Wheelchair Scale. The 7550
wall-mount wheelchair scale features a unique fold-up storage design that saves space when
not in use. The 7550 easily accommodates most wheelchairs with its spacious 36 in W x 33 in
D / 91 cm W x 84 cm D platform, and yet requires very little floor space when folded up. The
slim 7.3 in / 18.5 cm profile takes up minimal space when installed in a medical facility hallway,
clinical office, or patient room. When you’re ready to weigh, simply lower the platform and the
gas spring lifting mechanism will gently lower it into place. The patient may be easily rolled
onto the scale in a wheelchair, weighed in a chair, or while standing. The scale features a high
1,000 lb x 0.2 lb / 450 kg x 0.1 kg capacity for bariatric weighing, two-way ramps, and built-in
Wi-Fi and Bluetooth 5.0 for EMR/EHR.
This manual is provided to guide you through the setup and operation of your scale. Please
read it thoroughly before attempting to set up or operate your scale and keep it available for
future reference.
This manual is for the following models of the 7550 Wall-Mount Fold-Up Wheelchair Scales:
7550, 7550-AC, and 7550KGEU

SITE PREPARATION REQUIREMENTS
The Detecto 7550 Wall-Mount Fold-Up Wheelchair Scale is a precision weight indicating
instrument. As with any precision instrument, it requires an acceptable environment to operate
at peak performance and reliability. This section will assist you in obtaining such an
environment.
Environmental
For indoor use only.
Suitable for dry environments only RH < 90% and non-condensing environments.
NEVER allow the scale to get wet.
The scale meets or exceeds all certification requirements within a temperature range
of 14 to 104 °F (-10 to +40 °C).
The scale should be placed out of direct sunlight and to provide adequate air circulation, keep
the area around the scale clear.
Do not place the scale directly in front of a heating or cooling vent. Such a location will subject
it to sudden temperature changes, which may result in unstable weight readings.
When using the AC power adapter, ensure that the scale has good, clean AC power and is
properly grounded. In areas subject to lightning strikes, additional protection to minimize
lightning damage, such as surge suppressors, should be installed.
Electrical Power
The Detecto 7550 Wall-Mount Fold-Up Wheelchair Scale has been designed to operate from a
100V to 240V AC 50/60Hz 12V DC 1A wall plug-in UL/CSA listed AC power adapter (Cardinal
part number 6800-1045). NOTE: On installations using 220V to 240V AC, use the optional 100
to 240V AC 12V DC 1A Multi-Pin Input AC power adapter (Cardinal part number 6800-1047).
The socket-outlet supplying power to the indicator should be on a separate circuit from
the distribution panel and dedicated to the exclusive use of the indicator.
The socket-outlet shall be installed near the equipment and shall be easily accessible.
Electrical Noise Interference
To prevent electrical noise interference, make certain all air conditioning and heating
equipment, lighting, or other equipment with heavily inductive loads, are on circuits separate
from the system. These sources of disturbances can affect the operation of the scale. Steps
must be taken to prevent possible adverse effects on the scale. For example, using simple line
filters, isolation transformers, power regulators, or uninterruptible power supplies.

INSTALLATION
Choose the Scale Location
The scale should be installed in a location with a flat, level floor. Note that the weighing
platform will not sit completely against the floor. This will not affect the accuracy of the scale as
the weighing platform will settle to the floor when the patient is placed on the scale.
Back Load Cell
Front Load Cell
1/8” – 1/4” Clearance
NOTE: The front load cells of the weighing platform will be off the floor.
The rear load cells must be sitting completely on the floor.
There should be 1/8” to 1/4” clearance
between the sides of the scale frame and the
floor. This clearance is required for the lift
mechanism to close completely. The included
shims can be used to raise the scale if there
are slight imperfections with the floor or wall
mount installation that sits the wall mount too
low and prevents the scale from closing
completely. If the wall mount is too high, the
rear load cells will not touch the floor when the
weighing platform is lowered. If the wall mount
is too high, it must be moved lower on the wall
or the scale will not function correctly.
NOTE: It may be necessary to remove any base molding/chair rail/wall guard or to
remove a section of the base molding/chair rail/wall guard to provide space to mount
the scale in a true vertical position. An alternative method would be to shim the wall
mount away from the wall to accommodate any base molding/chair rail/wall guard.

INSTALLATION, CONT.
Install the Wall Mount
NOTE: Due to the various types of wall construction, no mounting hardware is
furnished with the scale. Appropriate mounting hardware suitable to the wall’s
construction will need to be obtained to secure the wall mount to the wall.
The wall mount allows the scale to be adjusted up or down and left or right to accommodate
floors that may not be perfectly flat. This ensures the accuracy of the weighing platform and
prevents undue stress to the scale.
The wall mount should be secured to the wall
using mounting hardware suitable to the wall’s
construction. The six (6) holes (in groups of
two, sixteen (16) inches apart) in the wall
mount, allow for 1/4" hardware to be used to
secure the wall mount to the wall.
1. Determine the desired location where the
scale is to be mounted.
2. With an assistant, place the wall mount
against the wall. Make sure it’s level and
35 1/2” from the top edge of the wall mount
to the floor.
3. Mark the holes to mount the wall mount.
4. Remove the wall mount and drill the
required diameter holes for the mounting
hardware used.

Battery Operation
The scale can use six C-size Alkaline, Ni-Cad, or
NiMH batteries (not included). You must first obtain
and install the batteries before operations can begin.
The batteries are contained in a battery holder that is
attached to a removable panel on the side frame of
the scale and secured in place with a thumbscrew.
CAUTION! The scale can be operated
from Alkaline, Ni-Cad, or NiMH batteries.
All six batteries must be of the same type.
They must all be Alkaline, all Ni-Cad, or all
NiMH. DO NOT mix Alkaline and Ni-Cad or
NiMH batteries.
NOTE: The scale does not have a battery
charging circuit. Should you wish to use
rechargeable batteries (Ni-Cad or NiMH),
they must be fully charged before
installing. When discharged, the Ni-Cad or
NiMH batteries must be removed and
placed in an external charger to recharge.
Battery Status
Removable
Battery
Panel
The battery status will be displayed when
batteries are installed. A number will be displayed
in the upper right corner of the touchscreen
indicating the level of charge remaining in the
batteries. For example, 100 = 100% charge,
75 = 75% charge, and etc...
When the batteries are at the point they need to
be replaced (Alkaline) or recharged (NiCad or
NiMH) and the battery voltage drops too low for
accurate weighing, the scale will automatically
shut off and you will be unable to turn it back on.

7550 OWNER’S MANUAL
CALIBRATE SCALE
Calibration Modes
The 7550 Wall-Mount Fold-Up Wheelchair Scale has four modes that can be used to perform
calibration. The modes are as follows:
1 = SMARTCAL
SmartCal is the most precise method of calibration. It requires that a calibrated load be
placed over each load cell of the scale platform only once. In this method, the scale will be
able to derive calibration constants, which will be used to combine information from each
load cell into scale weight.
During SmartCal, the display will prompt for the test load to be applied over a particular load
cell. With a scale that has four load cells, the order will simply be cell 1, cell 2, cell 3, and
cell 4. This order is used so that calibration can be done using a test weight with a minimal
amount of maneuvering required. Refer to the illustration below.

NOTE: This is the side of the

Load Cell and Load Placement
2 = Two Calibration Points
This is a standard calibration method requiring an empty scale and one weight. This method
uses two calibration points (an empty scale and the full test load on the scale) to establish a
zero (no load) calibration value and to span the indicator.
3 = Three Calibration Points
This method requires an empty scale, two weights, and uses three calibration points (an
empty scale, half the test load, and the full test load on the scale). The three points
correspond to zero (no load) weight, mid-point weight, and test load (weight).
4 = Four Calibration Points
This method requires an empty scale, three weights, and uses four calibration points (an
empty scale, one-fourth of the test load, half the test load, and the full test load on the
scale). The four points correspond to zero weight, quarter-point weight, mid-point weight,
and test load (weight).

POSSIBLE SOLUTIONS
AC Operation:
Is the AC power supply fully inserted into the wall receptacle?
Check the wall receptacle for proper AC power. Try another
electrical appliance in the same receptacle. Does it work?
Check the circuit breaker.
Has there been a power failure?
The display does not
turn on.
Incorrect weight is
displayed
Weight is not displayed
62
Battery operation:
Check if the batteries are installed and correctly.
If Alkaline, remove the old batteries and replace them with
new ones.
If NI-CAD or NiMH, remove the discharged batteries and
replace them with fully charged ones. Place the discharged
batteries in an external charger to recharge.
Make sure the weighing platform is not touching an adjacent
object. Have proper operation procedures been followed?

7550 OWNER’S MANUAL
CARE AND CLEANING
NOTE: The Detecto 7550 Wall-Mount Fold-Up Wheelchair Scale contains no userserviceable parts and maintenance should be limited to cleaning it thoroughly on a
routine basis and battery replacement as required.
Always remove the power before cleaning.
DO NOT pour or spray water directly on the indicator to clean. The indicator is not
waterproof and covering it with water will damage it and void the warranty.
DO NOT use wire brushes, abrasives, or cleaning tools such as steel pads and
scrapers, which will scratch the surface. Instead, use soft cloths or plastic scouring
pads for cleaning.
DO clean the indicator with a damp soft cloth and mild non-abrasive detergent.
When possible, use treated water. Hard water can leave behind deposits. Soft water is
much gentler on the indicators and painted steel’s surface.
Avoid the use of acetone, thinner or other volatile solvents, and abrasive type cleaners
for cleaning. If required, a mild solvent such as mineral spirits can be used to remove
oil, grease, tars, wax, and similar substances. Use a cloth dampened with mineral
spirits, and apply only to contaminated areas. Follow up the use of this mild solvent
with detergent cleaning and rinsing.
