1. DESCRIPTION OF DEVICE
1.1 Congratulations!
By purchasing the seca 284 measuring station you
have acquired an extremely accurate and robust
device.
For more than 170 years, seca has devoted its
experience to health care and, as the market leader in
many countries, is constantly setting new standards with
its innovative weighing and measurement developments.
1.2 Intended use
The seca 284 measuring station is mainly used in
hospitals, doctors' surgeries and inpatient care
facilities, in accordance with national regulations.
The measuring station is used to determine height and
weight. Wireless transmission of the height to the multi-
functional display enables automated calculation of the
Body Mass Index (BMI) and Body Fat Rate (BFR).
The seca 360° wireless network allows the measured
results to be transmitted wirelessly to a seca wireless
printer or a PC equipped with the seca analytics 105
software and the PC equipped with the
seca 360° wireless USB adapter 456.

4.2 Assembling the device
The first column element and the head slide are already
installed on the base of the device in the factory.
Perform the remaining assembly with the assistance of
another person. Due to the large overall height, we
recommend placing the components on the floor and
not uprighting the device until it is fully assembled.
Proceed as follows.
Install second column
element
To connect the column elements, proceed as follows:
1. Screw a threaded rod hand-tight into the elongated
nut of the first column element.
2. Slide an column element over the threaded rod
onto the first column element.
ATTENTION!
Damage to device due to assembly errors
If the upright connector and cover cap are
mixed up, the device cannot be assembled as
intended.
– When installing the second column element,
ensure that you use the upright connector
(see “Scope of supply” on page 75).
3. Position the upright connector on the second
column element so that the threaded rod protrudes
from the hole of the upright connector.
4. Screw an elongated nut onto the threaded rod.
5. Tighten the elongated nut.

Before you get started … • 77
English
Install the
multifunctional display
The multifunctional display is hooked into the groove of
the column element and fixed with a clamping screw.
The installation height is freely selectable.
1. Insert the T-slot nut of the multifunctional display
into the groove of the second column element.
2. Tighten the two hexagon socket head screws to fix
the multifunctional display in the required position.
3. Guide the connection cable of the multifunctional
display into the groove of the column element up to
the base of the device.
4. Pull the connection cable through the hole in the
base of the device.
ATTENTION!
Malfunction due to installation errors
If the cables are installed so that they are
subjected to large mechanical stress, faulty
displays and failure of the display can result.
–Layallcablessothattheyarenotbenttoo
tight and the plugs are not kinked.
5. Wind the free end of the connection cable onto the
cable winding in the base.
6. Plug the connection cable plug into the matching
socket of the weighing platform.

78 •
7. Use the two cable clips to fix the connection cable
into the groove of the column elements.
8. Swivel the multifunctional display so that you can
easily read it.
Install the third column
element
To connect the column elements, proceed as follows:
1. Screw a threaded rod hand-tight into the elongated
nut of the second column element.
2. Push the column element over the threaded rod
onto the upright connector of the second column
element.
3. Position the end cap on the second column
element so that the threaded rod protrudes from
the hole of the end cap.
4. Place the plain washer on the free end of the
threaded rod.
5. Place the nut on the free end of the threaded rod.
6. Tighten the nut.
7. Place the decorative cap on the nut.

Before you get started … • 79
English
Installing the push-in
scale
ATTENTION!
Incorrect measurements due to installation
errors
If the push-in scale is installed incorrectly the
head slide cannot determine any usable
readings.
– Align the push-in scale so that the printing
remains visible when the scale is pushed into
the groove.
–Alignthepush-inscaleso that the area which
shows the product number forms the bottom
end.
–Ensurethatthepush-in scale latches into
position under the end cap.
Push the push-on scale into the groove in the side
of the column elements until the scale latches into
position under the end cap.
4.3 Set up device
ATTENTION!
Incorrect measurement with force shunt
Correct measurements cannot be taken if the
patient's weight is not fully positioned on the
weighing area.
–Setupthedevicesothatitonlymakes
contact with the ground via the foot screws.
– Set up the device so that the weighing area
does not touch any other objects.
–Whileyouareweighing,ensurethatthe
patient does not touch the upright of the
device.
1. Place the device on a flat, stable surface.

80 •
2. Align the device by turning the foot screws.
The air bubble in the spirit level must be precisely
positioned in the middle of the circle.
3. Tighten the thumbscrews in the direction of the
arrow.
The foot screws are secured against adjustment.
4.4 Transporting the device
The device is equipped with two castors, which enable
it to be transported over short distances.
CAUTION!
Risk of injuries and damage to the device
The device must be tilted. The large overall
height of the device can result in injuries and
damage to the device.
– Ensure that there are no other persons in the
immediate vicinity.
– Ensure that there are no objects in the
immediate vicinity.
1. Unplug the power supply unit from the socket.

English
2. Tilt the device backwards until it can freely move on
the castors.
3. Transport the device to its new location.
4. Upright the device.
5. Plug the power supply unit into the socket.
4.5 Connecting the power supply
The head slide is supplied with power from batteries.
The scales and the multifunctional display are run with
a power supply unit.
Insert batteries The battery holder supplied already contains 4 mignon
batteries, type AA, 1.5 volt. To connect the power
supply for the head slide, proceed as follows:
1. Remove the cover of the battery compartment.
2. Remove the connection cable from the battery
compartment.
3. Connect the battery holder to the connection cable.
4. Insert the battery holder into the battery
compartment.
ATTENTION!
Damage to device and malfunction due to
clamped or pinched cable
– Laythebatterycablebefore closing the
battery compartment so that it cannot get
clamped between the cover and the battery
compartment.
5. Slide the cover onto the battery compartment until
it audibly latches into position.
