T2 - Train the Trainer: Making Effective Presentations
Dilip Shah, E = mc3 Solutions
Technical Subject matter experts are frequently required to train a broad spectrum of individuals, including co-workers. They frequently think that facts, statistics and data speak for themselves. Facts require analysis, assessment, and evaluation. Facts require translation and interpretation from their knowledge base to that of the audience. The key to successfully presenting complex information is not what they say or do but what their audience hears and sees. Their ability to communicate simply, passionately and clearly will often determine whether the audience understands the content being delivered. This workshop shall demonstrate some effective presentation techniques with hands on exercises that will change the way one makes their presentations in the future.

T3 - An Introduction to Instrument Control and Calibration Automation in LabVIEW
Logan Kunitz, National Instruments
Automation of instrument calibration improves repeatability of service, reduces manpower requirements, and improves service margin. Many calibration laboratories understand the benefits of automation, but feel they lack the appropriate software development skills to perform coding tasks. Modern programming environments and tools are extremely powerful, but can seem daunting to laboratory engineers. Alleviating these concerns, a number of software companies supply simplified tools and libraries to ease the interactions between calibration standards and automation software. Additionally, programming tools exist that are designed with the automation engineer in mind. During this two day hands-on tutorial, session participants will explore the LabVIEW environment, learn to develop, instrument control, data-logging, and measurement analysis applications. At the end of the course, they will be able to create applications using basic design templates and architectures to automate processes, acquire, process, display, and store real-world data.

T4 - ASTM E617: Standard Specification for Laboratory Weights and Precision Mass Standards (2013 Revision)
Val Miller, NIST OWM & Mark Ruefenacht, Heusser Neweigh
Mass reference standards are used daily in metrology laboratories for calibration of weights, torque devices, force gauges, balances, and other gravimetric applications; and used extensively in measurement assurance and quality control programs for intermediate checks of weighing instruments for accuracy and proper functioning. In 2013 ASTM E617: Standard Specification for Laboratory Weights and Precision Mass Standards was updated to meet the changing needs in industry and metrology. While the overarching goal was to align with international standards such as OIML R111: Weights of Classes E1-M3, Metrological & Technical Requirements, the outcome was a major revision to the weight class standards, specifications, and recommendations applicable to users in the U.S. New requirements resulting from the new tolerance classes ASTM Class 00 and Class 000 will be reviewed with application recommendations. Additionally, we will compare and contrast the three documentary standards (ASTM E617, OIML R111 & NIST Handbook 105-1: Specification and Tolerances for Field Standard Weights, NIST Class F) used for weights specifications and tolerances in the US; and apply various accreditation requirements from ISO/IEC 17025:2005.
At the end of this workshop, using your handouts and notes, you will be able to name the three major weight specifications used in the US, differentiate between the various weight classes, differentiate between appropriate mass calibration methods, choose the proper weight class for your measurement requirements, and outline the traceability of your mass measurements or weighing instruments. This workshop is recommended for metrologists, calibration technicians, ISO/IEC 17025 assessors, accrediting body personnel, and users of weights in the analytical laboratory and field calibration of weighing instruments.
T5 - Fundamentals of Calibration in Dimensional Metrology
Jim Salisbury, Amosh Kumar, Gordon Skattum, Mitutoyo
This tutorial provides an overview of calibration techniques and key issues in dimensional metrology. This tutorial will include a variety of hands-on practical calibration exercises. All the major types of dimensional calibrations will be discussed. We will start by studying the calibration, use, and traceability issues of the standards used in the field, such as gage blocks, ring gages, optical flats, thread wires, and length standards. We will then discuss the calibration of common small measuring tools such as micrometers, calipers, dial indicators, and height gages. Hands-on exercises in the calibration of small tools will include procedures, worksheets, and certificates. We will also discuss the field calibration of major instruments such as optical comparators and coordinate measuring machines. In addition to presenting specific calibration methods, a goal of the tutorial is on developing understanding of the principles behind the dimensional calibration methods thereby giving the attendee the necessary tools to extend the tutorial concepts to other types of calibrations. With that goal in mind, not only will recommended procedures be presented, but also optional methods, sources of errors and methods to reduce them, and techniques for estimating the uncertainty of measurement.

T9 - Running the Effective Laboratory Better - Data Driven Improvements that Matter
Jesse Morse (Morse Metrology), Malcolm Smith (WesCan)
Today's business and organizational climates have usurped traditional
"seat-of-the-pants" calibration management by insisting on continuous
improvement and the use of data based management decisions. Caught up in
this new paradigm are independent calibration companies and calibration
laboratories operating within and servicing their own organizations.
This "How To" tutorial focuses on getting your calibration operation to
maximum operational effectiveness, which will lead you directly to
improvements in efficiencies. The tutorial covers five areas where
performance measurement is critical in running an effective calibration
operation. The five areas are: (1) customer satisfaction, (2) quality,
(3) service levels, (4) productivity, and (5) finance. You will learn a
range of necessary metrics and tools to help establish baselines and
laboratory performance over time, which you can use to establish goals
and monitor performance in each of the five mentioned areas.
Suggestions on how you might use these tools in practice will be
provided. Also, the tutorial includes examples of measurements you need
for process improvement projects, along with examples of real life,
practical experiences in implementing the many new ways of thinking
associated with the paradigm. Anyone involved in or responsible for
calibration management should take this tutorial.

T15 - Calibration of Microwave Power Sensors
Andy Brush, Tegam
Sensors that measure low-power (below 100 mW) levels of guided RF
energy in the frequency range from 100 kHz to over 100 GHz have a wide
range of industrial uses. Traceability of these sensors to the SI units
is complicated, involving conversion of RF energy to thermal energy
and substituting DC energy. Additionally, measurement of RF scattering
parameters is required to reduce error in calibration transfer. When the
measurand is calculated from complex scattering parameters, DC voltage
and DC resistance, the propagation of uncertainty is particularly
involved. This tutorial starts with a theoretical basis for the
transfer of RF power, then explains the practice of actually
calibrating and adjusting RF power sensors, including the measurement
of power nonlinearity. After a theoretical foundation is established,
practical examples will be worked, showing students how to create their
own uncertainty budgets for RF power calibrations. Multiple methods for
estimating uncertainty will be presented. To cap the tutorial, a
common RF power sensor will be calibrated and adjusted using commercial
automation software, and the setup and output will be explained from
the perspective of the lab technician. This class is suitable for most
technicians or engineers with a basic knowledge of RF equipment.
Complex numbers and differential calculus are employed, briefly,
however skill with these concepts are not required for this course.

background knowledge to identify and develop strategies for application
to their own specific calibration operation. All participants will be
provided with a student workbook which documents the information that
was presented, contains useful exercises, and provides a list of helpful
resources for future reference and study.The participants will be able

T23 - Pipette Calibration, Use, and Uncertainty for the Metrologist, Assessor and Laboratory User
Dr. George Rodrigues and Mark Ruefenacht
Pipettes and other Piston Operated Volumetric Apparatus (POVA) are
taking an increasingly important role in the laboratory for accurate
small volumetric measurements. These devices are numerous, relatively
inexpensive and deceptively simple in appearance and function.
Experience shows many misconceptions and inconsistencies in use,
calibration and uncertainty analysis of pipettes. This hands-on workshop
will address proper pipette usage, pipette calibration, volume
measurement methods, and uncertainty analysis. Participants
will learn and practice proper pipetting technique, and investigate the
impact that technique variation has on accuracy and precision of
dispensed volume. Sample uncertainty budgets for the calibration and use
of pipettes will be shared and reviewed. Both gravimetric
and photometric methods of volume measurement will be included, along
with means for establishing traceability to the SI. Participates
will use gravimetric and photometric equipment to evaluate the impact
that user, pipette and measurement method have on the overall
uncertainty to the calibration process.
Documentary standards and other resources for pipette user training,
specification setting, and creating or evaluating calibration methods
will be provided.
At the end of this workshop, using your handouts and notes, you will
demonstrate good pipette technique, describe the sources of errors in
pipette calibrations, and list the major components for estimating
measurement uncertainty in pipette calibrations and use. This workshop
is recommended for metrologists, calibration technicians, ISO/IEC 17025
assessors, accrediting body personnel, and users of pipettes and POVA in

T21 - Force Calibration
Mike Tovey, Tovey Engineering
Force calibration is a special discipline with many considerations not common to other areas of metrology. Often measurement uncertainties are underestimated due to the omission of significant error sources. Metrologists must consider both mechanical and electrical boundary conditions to achieve calibrations with low measurement uncertainties. Factors such as second order material responses, and interaction of undesired parasitic loading due to fixture characteristics, misalignment of load frame components, stiffness, etc. can have significant influence on the measurement result. This tutorial will cover the characteristics of force transducers, force calibration methods, force calibration standards (E74 and ISO 376) and measurement uncertainty models for primary standards, secondary standards and field transfer standards. The tutorial begins at a basic level and leads to discussion of more complex issues.
T22 - Fundamentals of Radiation Thermometry Calibration
Frank Liebmann, Fluke Calibration
This session is an overview of the basic knowledge necessary to perform radiation thermometer calibrations. The presentation is divided into two parts. The first part is a lecture covering the basics of radiation temperature measurement and infrared thermometry calibration. The second part is a hands-on portion which covers the steps necessary to make a calibration measurement, plus a number of tests to determine measurement uncertainty, and the computation of uncertainties following international standards. The attendee will be provided with a spreadsheet to facilitate the computation of uncertainty. The type of radiation thermometer covered in this presentation is an infrared thermometer with a thermopile detector and an 8 - 14 µm bandwidth. However, the principals taught are applicable to other classifications of radiation thermometers to include radiation thermometers with pyroelectric detectors and thermal imagers. The presentation is geared to those who are new to radiation thermometer calibration, those who need a refresher on the subject, and to those who would like to perform better calibrations.
