Documentation Conventions

The following paragraphs describe some of the conventions that are used in your MTS manuals.

Hazard conventions Hazard notices may be embedded in this manual. These notices contain safety

information that is specific to the activity to be performed. Hazard notices immediately precede the step or procedure that may lead to an associated hazard. Read all hazard notices carefully and follow all directions and recommendations. Three different levels of hazard notices may appear in your manuals. Following are examples of all three levels.

Danger notices indicate the presence of a hazard with a high level of risk which, if ignored, will result in death, severe personal injury, or substantial property damage.

Warning notices indicate the presence of a hazard with a medium level of risk which, if ignored, can result in death, severe personal injury, or substantial property damage.

Caution notices indicate the presence of a hazard with a low level of risk which, if ignored, could cause moderate or minor personal injury or equipment damage, or could endanger test integrity.

Notes Notes provide additional information about operating your system or highlight

easily overlooked items. For example:

Note Resources that are put back on the hardware lists show up at the end of

the list.

Special terms The first occurrence of special terms is shown in italics.

Illustrations Illustrations appear in this manual to clarify text. They are examples only and do

not necessarily represent your actual system configuration, test application, or software.

Introduction

The video extensometer is available in models for the simple longitudinal strain to the advanced PRO and DEV models that integrate a machine control system. This no-contact system of mechanical tests use video for the analysis of polymers, elastomers, metals strains, and so forth.

Version LC X allow you to measure longitudinal strain. Version LC XY allows

you to measure transverse strain. Version LC XY-b allows you to determine the volumetric strain.

Models

These versions are installed on the computer provided with your tensile testing machine and are well adapted for large strains and tests at high or low

temperature.

The principle of measurement is the following-up in real time of the barycenter position of the markers laid out on the tensile specimen.

The system deduces the strains from the markers ( information to the control machine software either by a RS232 connection or by transmitting +/- 10 V signal.
