Figure 13 Effect of damping on table vibration levels
The Smart Table uses the same materials and has the same main mechanical
characeristics as passively damped Newport RS series table. The dampers are
installed at two corners of the table adjacent to a long side. The exact position
of each damper is indicated by three flat-head screws that are flash with the
table top at the corners.
CAUTION
Please keep in mind that four sealed threaded holes in each
damper area are only 0.457 in (11.6 mm) deep. If you need to use
some of these holes, choose the length of the screws
accordingly. An attempt to use too long screws may cause
damage to the dampers and de-lamination of the table face sheet.
