Principle of Operation
The system communicates primarily through the controller. The controller contains sensor
conditioning cards for the system transducers and transfers data between the transducers and
the computer. The controller also communicates with the load frame via a frame interface
board (FIB) inside the load frame. The FIB links all the electrical components of the frame
together.
Hardware Controls
The hardware controls consist of:
• Emergency stop button - to be used whenever you need to stop the crosshead
immediately because an unsafe condition exists.
• Limit stops - these must be set before each test session to protect the operator against
unexpected crosshead movement.
• Control panel - lets you perform certain functions at the frame instead of at the
computer. These include starting and stopping a test and using the jog controls to
position the crosshead prior to installing a specimen.
Software
Control of the testing system is carried out via Instron Bluehill software. Setting test
parameters, operating the system, and collecting test data is done through the software
program.

Term Description
Test Method In Bluehill software, a test method is a file that contains a set of
defined parameters that the system uses to run tests, analyze the test
data, and produce calculated results.
Sample A group of material specimens, whose properties are studied and
compared to gain statistical or quality assurance information. For
example, you could take a specimen from different parts of a single
manufacturing run of a material to form a sample of the material. The
sample is then representative of the complete run and you can test it
to ensure that the material quality has remained stable over the
complete run. You perform the same test on each specimen in a
sample.
