HOW TO USE THE
ARCHIMEDE HR
It is suggested to use the Archimede instrument following these two modes:
• according to a vertical plane perpendicular to the axis of the contact wheels
(ie the axis of the workpiece to be measured horizontally). [Pic. 1]
• according to an horizontal plane perpendicular to the axis of the contact wheels
(ie the axis of the workpiece to be measured vertically), using the central and lateral
mechanical stops for a more accurate measurement and to avoid the arms bending due
to the weight of the instrument. [Pic. 2]. Using this mode, the operator must more
carefully place the instrument onto the piece to measure, controlling the pressure
applied. This pressure has to be kept between 1÷2 kg, to avoid any bending in the arms.
Any other measuring mode between the two staded above, it is not to be
performed;
although it is possible to proceed with the measurement of objects that are
not well aligned with the floor, the resulting measure would not be accurate and may be
affected by errors due to various factors - mechanical strain on the instrument arms - and
the difficulty of maintaining the contact wheels resting on the surface to be measured.
In any case when it is possible, it is recommended the use of mechanical stops (both in
horizontal and vertical mode).
For a better measurement accuracy, it is suggested to take the measure placing the
instrument on the piece to measure, first on the central hub, than, rotating it on the arms
.
