|
Analysis
Description Screen
-
The Analysis
Description Screen provides a separate screen for entering text and graphics information
that describe the overall analysis, measurement process, etc.
-
This screen also provides easy access to
other notes pages.
-
The screen contents are automatically saved with each
analysis and can also be saved as an external rich text format
file.

Improved Bias Uncertainty Estimation
-
The Parameter Bias
Uncertainty Worksheets for estimating uncertainty due to measuring
and/or subject parameter bias are a major redesign of the original
Parameter Tolerance Worksheets.
-
Parameter
tolerance limits can now be computed as a linear or
root-sum-square (rss) combination of a fixed value, % of
nominal or reading, % of full scale, and % of range.
-
A
built-in SpecMaster Worksheet
has been added for determining tolerances for parameters with complex
specifications.
-
The
user can now choose from a list of error distributions that
include Normal, Lognormal, Exponential, Quadratic, Cosine,
U-Shaped, Uniform, Triangular, and Student's t.
|
Expanded
Sample Statistics
-
The Measurement
Data Entry Worksheets for estimating uncertainty due to
measuring and/or subject parameter random (repeatability)
error are a redesign of the original Data Entry Templates.
-
There
are four options available for analyzing data samples: 1)
measured values, 2) measurement data recorded in sampled
cells, 3) measurement data recorded as sampled mean values and
standard deviations, or 4) mixed samples.
-
Up
to 2,000 sampled values can be entered into the Measurement
Results table.
-
Data
can be imported into the Measurement Results table from several
external file formats via the Data
Import Profile Screen.
-
The
built-in Sample
Statistics Screen for computing Statistics for
Selected Cells (i.e., sample subset) now includes a Normality
Testing feature.
-
Options
have been added for applying a Parameter
Bias Correction factor and/or Environmental Correction to the
computed mean value.
|
|
Improved
Environmental Factors Worksheets
-
The
Environmental Factors
Uncertainty Worksheet has been expanded to include up to
10
environmental factors.
-
The
drill-down
Tolerance
Worksheet for each environmental factor has been
significantly redesigned to estimate two types of
uncertainties: 1) uncertainty in an environmental/ancillary correction or
2) uncertainty due to environmental/ancillary variations.
-
Environmental
factor corrections can be applied to computed mean value of
the subject parameter or measuring parameter.
|
Enhanced
User Defined Error Worksheet
-
The
User
Defined Error Worksheet has been redesigned to include
some significant enhancements.
-
The
Parameter Value Equation now contain up to
1,000 root variables or quantities and an unlimited number of nested
variables.
-
Nested variables
are defined by separate equations that are entered after the parameter
value equation.
-
All
equations are entered in the extremely versatile and
non-proprietary VB Script format, which allows for the inclusion of logic
statements and other programmable
controls.
|
Enhanced
Error Source Worksheets
-
The Error
Source Uncertainty Worksheets, accessed via the Root
Variables table on the User Defined Error Worksheet, now
contains several major enhancements.
-
The
number of sample entries for Type A measurement uncertainty estimates has been
increased from 50 to 2,000.
-
The built-in
Sample
Statistics Screen can be used for computing Statistics for
Selected Cells and conducting Normality
Testing.
-
Type B error limits can be computed as a
linear or rss combination of a fixed value, % of
nominal or reading, % of full scale, and % of range or other
component.
-
The
user can choose from a list of error distributions to use in
the estimation of Type B measurement uncertainty.
-
The built-in Type B
Degrees of Freedom Calculator provides a useful tool for
estimating the degrees of freedom for heuristic (i.e.,
non-statistical) measurement uncertainty estimates.
-
The Copy Error Source function allows
users to copy information from one Error Source Uncertainty
Worksheet to another to reduce duplication of data entry.
-
Worksheet
contents can be saved as an external
file (*.esu) that can then be imported to other analyses.
|
Comprehensive
System Model Analysis Screen
-
The System Module Analysis and System Results screens have been combined into one
System Model Screen.
-
Selection of system modules for data entry and analysis has also
been improved.
-
Module output and sensitivity coefficient equations are now
entered in VB Script format that allows for inclusion of nested variables, logic
statements and other programmable controls.
|
Improved Correlation Analysis
Screen
-
The Correlation
Analysis Screen has been significantly redesigned to
provide a more powerful tool
for correlating error sources.
-
The Correlation Analysis Screen now allows drag and drop selection of correlated
errors from an error source list.
-
The correlation coefficient between two
error sources can be computed by entering pairs of data or entering a known
coefficient.
-
A
Compensating Biases option has been included to account for systematic biases in two variables that offset one another in computing the combined uncertainty.
|
Expanded
Analysis Reporting Capability
-
A variety of reporting levels are
now available via the Report
Options Screen for complete communication of analysis results.
-
Notes, charts and plots can now be selected for inclusion on report pages.
-
The Print Preview
Screen provides navigation through reports pages prior to
printing.
-
Analysis reports can be saved in Rich Text or
HTML file formats via the Print Preview Screen.
-
Analysis reports can also be copied and
pasted as images in Word, Excel, PowerPoint or other external
application.
