Caution
Never lay down or invert the extensometer unless the keep plate is in position.
The most common customer return is for tangled or displaced counterweight cables. The
counterweights must be secured by the keep plate when the extensometer is removed from
the testing machine:
1. Move the arm to the top.
2. Slacken the thumbscrew and slide the keep plate to clamp the counterweights. Re-
tighten the thumbscrew (see Figure 2-1 ).
