•
If the specimen is still extending at the end of the extensometer travel, or if specimen
break occurs, the clamp rods on the clamp assemblies rotate outwards, reacting against a
spring-loaded roller, to automatically release the specimen and prevent damage to the
extensometer.
•
The 2603-080 and 2603-084 extensometers are self-identifying, so that they can be
calibrated automatically on suitably equipped machines. The 2603-085 and 2603-086
extensometers are not self identifying and require different calibration procedures
depending on the load frame model and application software in use. Refer to
“Calibration” on page 3-3 for details.
•
The full scale travel can be set to either SI units or US Customary units. The
extensometer is shipped with the SI units selected.
