Note: Remember, to ensure the specified IP67 performance, the following items will
need to be intact and securely assembled onto the indicator.
• Spindle Bellows
• Back lug with Gasket
• Stem Cap
• Data Output Cover or Data Cable with Gasket
Note: All items that have screws will need to be secured at least finger tight.
4.1 Accessories
The 2900 series comes standard with a Lug-
On-Center back. The back is easily removed
by unscrewing the four screws as shown in
Fig.19.
Do not touch any of the inner workings of the
indicator, and protect them from liquids, dust,
and any other foreign matter. Replace the
back-lug as soon as possible. Some examples
of the different back-lugs are listed below.
The Contact Point is another one of the parts
on your indicator that is interchangeable. The
contact point can be removed by carefully
while holding the spindle firmly with one hand
and then unscrewing it counter- clockwise
with your other hand. Replace the contact point
the same way, turning the tip on clockwise.
Remember to tighten the tip finger tight.
Excessive radial rotation of the spindle shaft
may cause your indicator to stop functioning
properly. Special contact points are listed on
the next page.
These backs, contact points and all of the available indicator accessories can be found
in your Starrett catalog or online at www.starrett.com/catalogs.
