SmartLock
The counterbalance of the Absolute Arm contains a smart locking
system to prevent the counterbalance to move down. A locking button
on the side of the arm is used to lock or unlock the counterbalance.
When the counterbalance is unlocked (standard operating position),
then whatever the position and the orientation of the wrist is, the
elbow of the arm will always be counterbalanced and follow the
imposed movement.
The unlock position is only an operating position and as soon as the arm is
left in its rest position, the counterbalance should be locked.
When the counterbalance is locked, then the position (= angle) of the
counterbalance is fixe and the arm is secured (it cannot fall).
This “locked” position can be also used to impose a height to the arm, for example to
prevent any obstacle above the arm.
To avoid hitting the elbow of the arm against an obstacle above the arm, it may be helpful to lock the
counterbalance with the lever.
The lock position also can be used to hold the arm in an angled position (e.g. 45°) to avoid hitting a low
ceiling, or when a small part needs to be measured or digitized: move down the elbow of the arm and lock
it, to get a comfortable position.
Locked position:
• Arm left for a long time
• An object above the arm hinders vertical
movement
• The part to probe or scan is very small
• To place back the arm in its case

When the arm is placed in its case, the counterbalance should be locked, to prevent any mistake when
taking it out.
