Mandrel: During the proof test, the fiber is wrapped around the mandrels. The right mandrel will rotate,
applying tension to the fiber.
Clamp: The clamps hold the fiber taut between the mandrels and keep it from slipping during the proof
test.
Release Button: The buttons are used to release the tension on the clamps, allowing the fiber to be
inserted or removed from the mandrel.
Ramp Screw: The screw is used to adjust the ramp rate (the rate at which fiber tension increases during
the proof test). To decrease the ramp rate turn clockwise; to increase the ramp rate turn
counterclockwise.
