Software Verification and Validation
MTS software is developed using established quality practices in accordance with the requirements detailed in
the ISO 9001 standards. Because MTS-authored software is delivered in binary format, it is not user accessible.
This software will not change over time. Many releases are written to be backwards compatible, creating another
form of verification. The status and validity of the MTS operating software is also checked during system verification
and routine calibration of MTS hardware. These controlled calibration processes compare the final test results
after statistical analysis against the predicted response of the calibration standards. With these established
methods, MTS assures its customers that MTS products meet exacting quality standards when initially installed
and will continue to perform as intended over time.

Preface
Before You Begin
Safety first!
Before you use your MTS product or system, read and understand the safety information provided with your
system. Improper installation, operation, or maintenance can result in hazardous conditions that can cause
severe personal injury or death, or 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 manuals in paper or electronic form.
You may also receive an MTS System Documentation CD. It contains an electronic copy of the manuals that
pertain to your test system.
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
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. (for
general safety information, see the safety information provided with your system.)
Danger:
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.
DCPD Measurement System 9

Warning:
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:
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.
Other special text conventions
Important:
Important notices provide information about your system that is essential to its proper
function. While not safety-related, if the important information is ignored, test results may
not be reliable, or your system may not operate properly.
Note:
Notes provide additional information about operating your system or highlight easily
overlooked information.
Recommended:
Recommended notes provide a suggested way to accomplish a task based on what MTS
has found to be most effective.
Tip:
Tips provide helpful information or a hint about how to most efficiently accomplish a task.
Access:
Access provides the route you should follow to a referenced item in the software.
Example:
Examples show specific scenarios relating to your product and appear with a shaded
background.
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.
Electronic manual conventions
This manual is available as an electronic document in the Portable Document File (PDF) format. It can be
viewed on any computer that has Adobe Acrobat Reader installed.

General Safety Practices
If you have system related responsibilities (that is, if you are an operator, service engineer, or maintenance
person), you should study this manual carefully before you attempt to perform any test system procedure.
You should receive training on this system or a similar system to ensure a thorough knowledge of your
equipment and the safety issues that are associated with its use. In addition, you should gain an understanding
of system functions by studying the other manuals supplied with your test system. Contact MTS for information
about the content and dates of training classes that are offered.
It is very important that you study the following safety information to ensure that your facility procedures and
the system’s operating environment do not contribute to or result in a hazardous situation. Remember, you
cannot eliminate all the hazards associated with this system, so you must learn and remain aware of the
hazards that apply to your system at all times. Use these safety guidelines to help learn and identify hazards
so that you can establish appropriate training and operating procedures and acquire appropriate safety
equipment (such as gloves, goggles, and hearing protection).
Each test system operates within a unique environment which includes the following known variables:
• Facility variables (facility variables include the structure, atmosphere, and utilities)
• Unauthorized customer modifications to the equipment
• Operator experience and specialization
• Test specimens
Because of these variables (and the possibility of others), your system can operate under unforeseen
circumstances that can result in an operating environment with unknown hazards.
Improper installation, operation, or maintenance of your system can result in hazardous conditions that can
cause death, personal injury, or damage to the equipment or to the specimen. Common sense and a thorough
knowledge of the system’s operating capabilities can help to determine an appropriate and safe approach to
its operation.
Observe the prescribed safety practices before and during system operation.
It is the user’s responsibility to take the machine out of service and contact MTS Service if discrepancies in
system operation are found.
Hazard Placard Placement
Hazard placards contain specific safety information and are affixed directly to the system so they are plainly
visible.
Each placard describes a system-related hazard. When possible, international symbols (icons) are used to
graphically indicate the type of hazard and the placard label indicates its severity. In some instances, the
placard may contain text that describes the hazard, the potential result if the hazard is ignored, and general
instructions about how to avoid the hazard.

DCPD Measurement System Introduction
The direct current potential drop (DCPD) crack measurement system is paired with an MTS closed-loop
servohydraulic controller. The closed-loop controller provides specimen loading, and data acquisition and
storage. A typical materials test applies a load or force on a specimen to grow the crack. In fatigue crack
growth tests, the load is a dynamic load simulating a material in a rotating or dynamic environment such as
an aircraft engine. In fracture toughness or creep tests the load is static or slowly varying, simulating a material
in other environments such as a pressure vessel.
Theoretically, the DC conditioners found in the MTS controller could supply the constant current and amplify
the electrical potential drop, but these conditioners do not have enough current or amplification for typical
DCPD specimens. Therefore, the DCPD Measurement System electronics provide the current and amplify
the resulting potential drop. Then the high level signal (amplified to a value between 0.1V and 10 V) is brought
into the controller or data logging device.
