Identify system type To assist the Call Center agent with connecting you to the most qualified

technical support specialist available, identify your system as one of the following types:

• Electromechanical materials test system

• Hydromechanical materials test system

• Vehicle test system

• Vehicle component test system

• Aero test system

Be prepared to

Prepare yourself for troubleshooting while on the phone:

troubleshoot

• Call from a telephone when you are close to the system so that you can try

implementing suggestions made over the phone.

• Have the original operating and application software media available.

• If you are not familiar with all aspects of the equipment operation, have an

experienced user nearby to assist you.

Write down relevant

Prepare yourself in case we need to call you back:

information

• Remember to ask for the notification number.

• Record the name of the person who helped you.

• Write down any specific instructions to be followed, such as data recording

Preface

Before You Begin

Safety first! Before you attempt to use your MTS product or system, read and understand the

Safety manual and any other safety information provided with your system. Improper installation, operation, or maintenance of MTS equipment in your test facility can result in hazardous conditions that can cause severe personal injury or death and damage to your equipment and specimen. Again, read and understand the safety information provided with your system before you continue. It is very important that you remain aware of hazards that apply to your system.

Other MTS manuals In addition to this manual, you may receive additional MTS manuals in paper or

electronic form. If you have purchased a test system, it may include an MTS System

Documentation CD. This CD contains an electronic copy of the MTS manuals that pertain to your test system, including hydraulic and mechanical component manuals, assembly drawings and parts lists, and op eration and preventive maintenance manuals. Controller and application software manuals are typically included on the software CD distribution disc(s).

Documentation Conventions

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

Hazard conventions As necessary, hazard notices may be embedded in this manual. These notices

contain safety information that is specific to the task 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 the directions that are given. Three different levels of hazard notices may appear in your manuals. Following are examples of all three levels.

Note For general safety information, see the safety information provided with

your system.

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, equipment damage, or endanger test integrity.

Notes Notes provide additional information about operating your system or highlight

easily overlooked items. For example:

LX Laser Extensometer

Introduction

The MTS Series LX Laser Extensometers are precision, wide range instruments specifically designed for accurate, non-contact, measurement of strain on various materials under tensile or creep conditions. The instrument is completely self contained. It is housed in a single, compact enclosure and utilizes the latest stateof-the-art laser diode technology for high performance, low maintenance operation. The LX 500 is a high elongation version for measuring the strain of elastomeric materials. It has a range of 5 to 132 mm (0.2 to 5.2 in). The LX 1500 has a range of approximately 380 mm (approximately 15 in).

The laser extensometer includes a LCD display, a 4-button keypad, a 0 to 10 V (5 V optional) analog output, and a serial input/output port, all of which are accessible from the control panel. In addition, the unit can be operated locally from the control panel using the built-in keypad, or remotely via the Serial I/O Port.

MTS Series LX Laser Extensometer

LX Laser Extensometer Introduction

The laser extensometer uses a unique scanning laser beam technique to measure elongation entirely from one side of the specimen. Two tiny retro-reflective targets are attached to the specimen at the desired gauge length and the beam is scanned along the specimen in the direction of elongation. Reflections from these targets are then processed by the laser extensometer to provide measurement of elongation (strain). This approach eliminates the need for a separate Scan Receiver Unit mounted on the opposite side of the specimen.
