How to Install Extension Springs or Elastic Bands
Installing the extension spring or elastic band attachment system
involves replacing the quick attachment spring attachment adapters on
each arm of the extensometer with knife edge hold-downs and
attachment hooks.
Component Identification
Excessive torque on the extensometer arms can damage the
extensometer.
The extensometer arms can be damaged when mishandled.
Do not hold the extensometer case when loosening or tightening the
socket head cap screws. Use an adjustable wrench to hold the
extensometer arm or attachment adapter. Loosen or tighten only those
socket head cap screws on the arm being held with the wrench.
The attachment hooks are usually always installed between the knife
edge and knife hold-down on each arm of the extensometer. Depending
on the model of the extensometer and the type of mounting required, the
hooks are sometimes removed.
