Installation
Above ground Installation
It is recommended to lag bolt the ramp in place to keep the scale from moving during
use. First position the scale and ramp in the location that you intend on using the scale,
ensure that the scale is away from general traffic and that the chosen area is protected
from water, misc. debris, wind, and or vibration.
Once the location of the scale has been chosen, remove the scale from the ramp taking
care not to move the ramp. Using a black Sharpie mark the small bolt holes located on
the foot retaining plate shown in the image below.
Once these holes have been marked, remove the ramp and drill lag bolt holes where
the black Sharpie marks are located on the floor. Once the holes have been drilled
position the ramp back in place and secure it to the floor using lag bolts.

Now that the ramp is secured to the floor the scale base can be placed back into the
ramp. Ensure that the load cell feet sit within the foot retaining plate hole as shown in
the image below.
Level the scale by adjusting the load cell feet through the access holes using a flathead
screwdriver shown in the image below.
The scale is now ready to be connected to the indicator and calibrated. See the
indicator termination section for information on connecting the scale to its indicator.

In-ground Installation
The in-ground scale installation will require installation prior to concrete floor installation
or the cutting of the existing concrete floor for the scale to be installed. This is the more
labor-intensive of the two installations but is also the most desirable installation as the
scale is flush with the floor allowing the scale to be walked on/around as if it is part of
the floor.
When choosing a location for the in-ground scale it is important to consult with the
building engineers to ensure the scale is in a place that will not interfere with existing
building wiring, plumbing, etc., and at the same time ensure that the scale is away from
general traffic and that the chosen area is protected from water, misc. debris, wind, and
or vibration.
Consult with your concrete contractor to perform the pit frame installation. The pit frame
should be installed so that the top edge is even with the floor and surrounded by
concrete to ensure a solid and sound installation. Note: The pit frame will require
conduit to be run from the pit frame to a wall location directly behind the scale to run the
interconnect cable from the scale to the indicator. The image below shows the proper
installation of the pit frame.

Now that the pit frame has been completed, place the scale base in the pit frame
ensuring that there is roughly an equal amount of gap between the pit frame and scale
base around its perimeter. Note: Ensure that the interconnect cable is pulled through
the conduit at the same time the scale base is being installed to keep the cable from
tangling up or having the scale rest on the cable after its installed.
After the scale has been installed take a flathead screwdriver and adjust the scale base
feet so that it is level and even with the floor. Note: If the scale is installed and leveled
properly, you will be able to walk around the scale with a little sway but without any
metallic noise. The image below shows the location of the load cell foot adjustment
holes.
That concludes the installation of the Patient pit-style scale. For indicator termination
and calibration see the indicator termination section.

Indicator Termination and Calibration
It is the recommendation of B-TEK to have your scale calibrated and tested by a
certified scale company. This should not only be done for the installation but periodically
throughout the year as well. Having this done not only protects you and your patients
but also gives you peace of mind knowing your scale is in good working order and
working as it is intended to work.
Termination procedures vary from indicator to indicator. If you are using a B-TEK
indicator or indicator from another manufacturer, with your scale, please refer to the
technical manual for the termination of the indicator itself. Use the scale base
termination diagram below for terminating your indicator.
