7. CHECKS, CALIBRATIONS AND
ADJUSTMENTS
The device is calibrated in the factory during final testing carried out at
the manufacturer’s site.
Some adjustments (for example the friction mechanisms of the scissors
arm and extension arm) may need to be done once the installation has
been completed and are described in the installation chapter 6.
7.1 Arm adjustment
The arms may need adjusting in the following cases:
• the movement of the extension arm combined with the scissors arm
is not considered to be ergonomic by the end user; in this case it will
be necessary to adjust the extension arm frictioning mechanism.
• the scissors arm is not perfectly balanced; in this case you must
adjust the springs.
