MTS Axial Extensometers - Manual (Page 25)

Configuration 25
1. Check your installation drawing. If your extensometer needs an
attachment adapter, perform the appropriate procedure before
proceeding.
2. Separate the spring retainers from the springs by loosening (do not
remove) the socket head cap screws.
3. Mount one spring in the appropriate hole in the attachment adapter
as determined by the specimen dimensions (see the installation
drawing).
4. Slide the spring retainer over the end of the spring and tighten the
socket head cap screw. Orient the spring retainer in such a way that
it will not interfere with movement of the extensometer arm.
5. Select the matching spring and repeat Step 3 and Step 4 for the
other extensometer arm.
How to Install an Attachment Adapter
Some extensometers do not have anchor holes in their upper and lower
arms and require attachment adapters to be mounted. Others may need
an attachment adapter when an extender is used.
1. Zero the arms of the extensometer. Depending on the extensometer,
this can be accomplished using the zero pin, stop block, or a special
fixture.
