Ottobock 3D L.A.S.A.R. Posture Instrucciones De Uso página 105

Does the force measurement plate have to be centred in front of the case?
•
Yes, to achieve the best possible accuracy.
• What is the best way to lay the cables from the case?
The camera cables should be kept out of the working area for the O&P professional as far as possible to avoid trip­
ping (section "Setup" – see Page 75). The cable between the case and force measurement plate should be laid as
straight as possible and has a detachable magnetic connection.
Using the product
Can the alignment guidelines be used in 3D mode?
•
The stored alignment guidelines only apply when 3D mode is deactivated.
Can the device be used for bench alignment without the L.A.S.A.R. Assembly?
•
No, since the weight of the prosthesis alone would be too low to work with sufficient accuracy.
Error messages
What can be done if the error message "Connection failed" is displayed repeatedly even though the
•
mini-computer has booted up?
Check the WiFi settings on the tablet to verify that WiFi is active and connected to the network named
"3D_L.A.S.A.R._20XXXXXXX". If necessary, disconnect the power plug from the mini-computer and connect it to
the outlet again to perform a restart.
How is the error message "Missing ground contact" corrected?
•
Operate the force measurement plate on a firm, even surface. Distribute the load evenly or apply it to the centre of
the plate.
How can the error messages "Calibration failed", "Shift detected" and "Warning" be avoided?
•
Good lighting in the room, no backlighting for the cameras and a floor that is not too dark are important factors to
obtain a good image quality. The alignment of the camera stands and force measurement plate has to be carried
out according to the section "Alignment of the stands and force measurement plate" (see Page 83).
What can be done if the device calibrates frequently?
•
Make sure that none of the four LEDs on the force measurement plate are concealed from the perspective of the cameras. Remove reflective objects from the vicinity of the force measurement plate. Ensure constant, even light­
ing. Make sure that the camera and the force measurement plate are not exposed to direct sunlight (for instance
light coming through a window).
What can I do if the force measurement plate is connected but not found?
•
With the help of the live view on the tablet, position the force measurement plate so that it is as close as possible to
the lower edge of the image but the four LEDs are still visible. In the live view, the force measurement plate must
be visible at the bottom edge of the image, as close as possible to parallel and centred. Remove all reflective
objects from the vicinity of the force measurement plate. Ensure constant ambient lighting (consistent brightness).
Make sure the camera is not backlit (for instance by light coming in through a window). Check the connection of
the USB magnetic plug. Disconnect and reconnect the connection if necessary.
