1 Introduction
What is TableWare?

1.1
Introduction
What is TableWare?
TableWare is designed to calculate characterization coefficients for platinum,
thermistor, and thermocouple probes. The types of coefficients that can be calculated are: ITS-90 for platinum probes; IPTS-68 for platinum probes;
Callendar-Van Dusen for platinum probes; Polynomial for platinum and thermistor probes; and coefficients for thermocouple probes types B, E, J, K, N, R, S,
T, and AuPt.
The raw data used to calculate coefficients may be entered into the software directly or imported into the software from an ASCII text file. TableWare creates
a report that can be either printed to a printer or exported to an ASCII text file.
TableWare also generates Temperature vs. Resistance, Temperature vs. Ratio,
and Temperature vs. EMF tables based on ITS-90, IPTS-68, Callendar-Van
Dusen, Polynomial or Thermocouple coefficients.
1.2
License agreement
For information and details regarding the software End User License Agreement (EULA), refer to the online help file’s License Agreement topic.
1.3
Features
A list of new features and enhancements in version 2 of the TableWare follows:
Version 2.4
1.
The logos and graphics displayed in TableWare have been updated.
Version 2.3
1.
Prior to this version, the Shared Files Conflict dialog always appeared
when running the software in Windows NT with the file
COMMDLG.DLL listed. Even though the software works fine despite
this file conflict, this dialog no longer appears.
2.
When generating Temperature vs. Ratio tables, the Inverse Difference
column was incorrectly labeled “dT/dr”. The label has been changed to
correctly read “dT/dW”.
3.
When generating Temperature vs. Resistance tables or Temperature vs.
Ratio tables in °F, the values in the First Derivative (dr/dT) column and
Inverse Difference column (dT/dW) displayed the values as if the table
was in °C.
4.
The Extrapolating message incorrectly appeared when generating a table
when; a) the Table Scale was set to °F or K and, b) the Minimum Temp.
1
9933 TableWare
User’s Guide
and/or Maximum Temp. setting fell outside the recommended temperature range in °C.
5.
In version 2.2, an Overflow error sometimes occurred when attempting
to generate tables from thermistor polynomial coefficients that TableWare calculated. This problem has been fixed.
6.
A new range setting has been added for Type R and Type S Thermocouple probes. This range is named “-50.0°C to 1768.1°C (using extrapolation)”. Selecting this range allows TableWare to automatically determine
which reference function to use when calculating coefficients and table
values based on the temperature value. Selecting one of the other available ranges forces TableWare to use only the reference function for that
range.
7.
Temperature vs. EMF (mV) tables can now be generated as well as Temperature vs. EMF (μV) for thermocouple probes.
8.
Residuals for thermocouple probes are now displayed/printed in the scale
that the UUT readings were entered in instead of always being displayed/printed in Vμ.
9.
An Export button has been added to the Raw Data dialog, which allows
raw data to be saved to an ASCII text file in comma, delimited format.
Version 2.2:
2
1.
A warning message will appear when calculating thermocouple coefficients if one of the selected set-points is within ±5° of 0°C. The algorithm used to calculate thermocouple coefficients forces the EMF at 0°C
to 0.0µV. Therefore, using a set-point at or near 0°C when calculating
thermocouple coefficients may cause erroneous results. For best results,
use at least two set-points that are not near 0°C.
2.
The model and serial number labels used on the report and table are now
editable. These labels can be changed to display whatever information
your process requires. Simply enter the appropriate text in the Caption
and Value boxes on the Probe Information dialog. This information will
print on the report and table exactly as it is entered.
3.
The report and table now support page numbering in the “Page x of y”
format. For reports, Page Numbering dialog appears when the Print Report button is selected asking for the page number of the report and the
total number of pages. The report itself always fits on one letter-size
page. For tables, the starting page number is selected from the Table Options dialog. The number of pages depends on the temperature range as
well as the font size and is determined automatically by the software.
Adding this feature to the software made it necessary to create the table
twice: first to determine the number of pages, then to print the page numbers on each page. For this reason, it now takes twice as long to generate
a table.
1 Introduction
Features
If you want to create a document that includes the report and table, follow the
steps below:
a. Set the starting page for the table to “2”.
b. Print the table.
c. Print the report, setting the page number to “1” and the number of
pages to the same value that appears on the table.
d. If other pages need to included in the document, they may be inserted either before or after the report. Adjust the starting page number for the table and/or report accordingly.
4.
The table can now be printed in increments of 0.01°. Prior to version 2.2,
the minimum allowable increment was 0.1°.
Note: Generating tables over a large range using a small increment may
take a few minutes, especially on 386 and some 486 PCs.
5.
In conjunction with item 4 above, the default resolution for temperature
values on tables is now two decimal places.
Version 2.1.0.1
1.
Version 2.1 build 2.1.0.1 fixed a bug with the calculation of coefficients
and table values for ITS-90 Range 6.
2.
The resolutions that can be used now include up to 9 decimal places.
Prior to this version, the maximum number of decimal places was 7.
Version 2.1:
1.
Version 2.1 of TableWare has added the capability to calculate Polynomial coefficients for Platinum probes using a scale other than the scale of
the Reference readings. TableWare will automatically convert the Reference readings to the selected scale.
Version 2.0:
1.
A Print Preview window has been added so that reports and tables can be
viewed on-screen before printing.
2.
TableWare now allows tables to be exported to an ASCII text file. This
makes it possible to import the table into a spreadsheet or other
application.
3.
TableWare now has the capability of generating a table from coefficients
entered by the user. No raw data is required.
4.
The default printer may now be selected from the File menu. This option
allows the user to determine which printer (if more than one printer can
3
9933 TableWare
User’s Guide
be used) the reports and tables are printed to, or which printer driver is
used.
5.
1.4
The date that prints on the report and table can now be set by the user.

User’s Guide
Note: The accepted thermistor model is based upon the logarithmic resistance-temperature characteristic in terms of absolute temperature (Kelvin). The accuracy of a model based upon °F or °C has not been tested.
Therefore, TableWare always calculates polynomial coefficients for thermistor probes using Kelvin. If Reference readings are entered in °F or °C,
TableWare converts the readings to their Kelvin equivalent values before
the fit is computed.
Valid orders of the polynomial are from 3rd to 6th order. The default for thermistor probes is 3rd order. The number of coefficients calculated is one more
than the order of the polynomial (i.e. for a 3rd order polynomial, 4 coefficients
are calculated). The minimum number of set-points needed must exceed the order by 1 or more.
The user is allowed to select whether or not the Steinhart-Hart method is used

Figure 14 Select Calculation Scale dialog
Many readout instruments that accept Polynomial coefficients require that the
coefficients be calculated using Reference readings in a particular temperature
scale. This feature allows Reference readings to be used as entered on the Raw
Data dialog (with no conversion) or to be converted automatically to Kelvin by
TableWare. Prior to version 2.1, TableWare always calculated Polynomial coefficients after converting the Reference readings to Kelvin.
Note1: TableWare does not provide the option of converting Reference readings from °F to °C nor vice-versa. Also, if Reference readings were entered in
Kelvin, the Select Calculation Scale dialog will not appear and Polynomial coefficients will automatically be calculated using Kelvin.
Note2: The accepted thermistor model is based upon the logarithmic resistance-temperature characteristic in terms of absolute temperature (Kelvin). The
accuracy of a model based upon °F or °C has not been tested. Therefore, TableWare always calculates polynomial coefficients for thermistor probes using
Kelvin. If Reference readings are entered in °F or °C, TableWare converts the

User’s Guide
Note: If CJC readings are entered in temperature, the standard thermocouple coefficients for the selected thermocouple type are used to calculate the voltage at each reading. The calculated voltages are then added to
each corresponding UUT reading before calculating characterization coefficients for the UUT. If CJC readings are entered in voltage, they are
converted to the correct scale (i.e. mV or µV) and added to each corresponding UUT reading.
The yellow boxes designate the values that must be filled in for the type of coefficients being calculated to produce an exact solution. Entering values into
the white boxes is optional and produces an overdetermined solution. Section
3.8, Methods Used for Calculating Coefficients, contains additional
information.
Note: The algorithm used to calculate thermocouple coefficients forces
the EMF at 0°C to 0.0µV. Therefore, using a set-point at or near 0°C when
calculating thermocouple coefficients may cause erroneous results. For
best results, use at least two set-points that are not near 0°C (more than
±5°C).

• Temperature vs. Resistance - For ITS-90, IPTS-68, Callendar-Van Dusen,
and Polynomial coefficients
• Temperature vs. Ratio - For ITS-90 and IPTS-68 coefficients only
• Temperature vs. EMF (μV) - For Thermocouple coefficients only
• Temperature vs. EMF (mV) - For Thermocouple coefficients only
The choices for temperature scales are °C, °F, and K. The temperature scale
defaults to the Reference Scale selected on the Raw Data dialog when coefficients are calculated or to °C when generating a table after entering
coefficients.
The minimum temperature, maximum temperature and step size must be entered. These values are in the currently selected temperature scale. The minimum temperature and maximum temperature values are limited to –270°C and
2650°C (–454°F and 4802°F) respectively. However, the equations used to generate table values may not be able to calculate values over the full range. If a
message is displayed during calculations stating that a calculation error occurred, you may need to increase the minimum temperature or decrease the
maximum temperature. The Table Temperature Ranges chart in Section 3.6 lists
the recommended ranges for generating tables.
Note: Changing the selected temperature scale converts the minimum and
maximum temperature values to that scale.
The step size is the increment between each temperature value on the table. The
step size must be between 0.01 and 100.00. The step size defaults to 1.00.
Below the temperature settings are various options for the selected type of
table.
• For Temperature vs. Resistance tables, the first derivative value can be
printed by selecting the “Print first derivative (dr/dT)” option.
• For Temperature vs. Ratio tables, the inverse difference value can be
printed by selecting the “Print inverse difference (dT/dW)” option.
• For Temperature vs. EMF (μV) tables, the error value can be printed by
selecting the “Print Error (μV)” option.
• For Temperature vs. EMF (mV) tables, selecting the “Print Error (mV)”
option can print the error value.

custom resolutions”.
Figure 24 Table Options - Resolutions
When the “Use default resolutions” option is selected, the values on the table
are printed using the default method: temperature values are always 2 decimal
places and all other values depend upon the magnitude of the value:
For values between –10 and 10: seven decimal places
For values between –100 and 100: six decimal places
For values between –1,000 and 1,000: five decimal places
For values between –10,000 and 10,000: four decimal places
For values between –100,000 and 100,000: three decimal places
All other values: two decimal places
When the “Use custom resolutions” option is selected, the values on the table
are printed using the formats selected by the user. Select the format for temperature readings with the Temperature drop-down list. Select the format for resistance, ratio or voltage readings with the appropriate drop-down list. Select the
format for the first derivative, inverse difference or error readings with the appropriate drop-down list.

9.
3.7.2
Residuals are calculated for each set-point used in calculating the coefficients with the exception of the Triple Point of Water set-point. Residuals
are always in the same scale as the Reference Probe readings.
IPTS-68 coefficients
The following requirements must be met when IPTS-68 is selected as the type
of coefficients to calculate for Platinum probes. For more information concerning the method used to calculate the IPTS-68 coefficients, see Section 3.8,
Methods Used for Calculating Coefficients.
1.
The Reference Probe readings must be in temperature (°C, °F or K).
2.
The UUT (test probe) readings must be in resistance (Ohms or KOhms).
3.
Exactly 4 set-points must be used:
39
9933 TableWare
User’s Guide
a) One set-point must be within a few degrees of 0°C (32°F or
273.15K) (preferably as close to 0°C as possible).

5.
3.7.3
Residuals are not calculated when calculating IPTS-68 coefficients.
Callendar-Van Dusen coefficients
The following requirements must be met when Callendar-Van Dusen is selected
as the type of coefficients to calculate for Platinum probes. For more information concerning the method used to calculate the Callendar-Van Dusen coefficients, see Section 3.8, Methods Used for Calculating Coefficients.
1.
The Reference Probe readings must be in temperature (°C, °F or K).
2.
The UUT (test probe) readings must be in resistance (Ohms or KOhms).
3.
At least 3 set-points must be used but no more than 10 set-points can be
used. If any one of the set-points is below 0°C (32°F or 273.15K), at
least 4 set-points must be used.
Note: This software automatically determines if the BETA coefficient
needs to be calculated based on the following criteria:
• The Reference reading closest to 0°C is not used to determine whether
BETA is calculated.
• If any other Reference reading is below 0°C, BETA will be calculated.
• Otherwise, BETA will not be calculated.
4.
One of the set-points used should be close to 0°C. This is not a requirement, however results of the calculations become less reliable when no
reading is near 0°C because the software must interpolate the reading at
0°C based on the readings provided.
5.
The following Callendar-Van Dusen coefficients are calculated:
a) R0
b) ALPHA
40
3 Coefficients menu
Requirements for calculating coefficients
c) DELTA
d) BETA (only calculated if criteria explained above is met)
6.
3.7.4
Residuals are calculated for each set-point used in calculating the coefficients. Residuals are always in the same scale as the Reference Probe
readings.
Polynomial Coefficients
The following requirements must be met when Polynomial is selected as the
type of coefficients to calculate for Platinum or Thermistor probes. For more
information concerning the method used to calculate the Polynomial coefficients, see Section 3.8, Methods Used for Calculating Coefficients.
1.
The Reference Probe readings must be in temperature (°C, °F or K).
Note: The accepted thermistor model is based upon the logarithmic resistance-temperature characteristic in terms of absolute temperature (Kelvin). The accuracy of a model based upon °F or °C has not been tested.
Therefore, TableWare always calculates polynomial coefficients for thermistor probes using Kelvin. If Reference readings are entered in °F or °C,
TableWare converts the readings to their Kelvin equivalent values before
the fit is computed.
2.
The UUT (test probe) readings must be in resistance (Ohms or KOhms).
3.
The order of the polynomial must be selected. Allowable choices are
from 3rd order to 9th order for platinum probes, and from 3rd to 6th or der for thermistor probes.
4.
For thermistor probes, the Steinhart-Hart method may be selected. Studies have indicated no significant loss in accuracy when using the
Steinhart-Hart method (eliminating the squared term) over the range of
–2°C to 70°C (28°F to 158°F). The formula used when the
Steinhart-Hart method is selected is:
1
= a + bln( RT ) + dln( RT )
T
For more information on this topic, refer to “Worldwide Capability in Thermistors”, Thermometrics, Inc., 1993, pages 14–15.
5.
For normal calculations, at least 4 set-points must be used but no more
than 10 set-points can be used.
6.
For Steinhart-Hart calculations, only 3 set-points should be used.
7.
The minimum number of set-points used must exceed the order of the
polynomial by at least 1 (i.e. for a 5th order polynomial, at least 6
set-points must be used).
8.
The following Polynomial coefficients are calculated:
41
9933 TableWare
User’s Guide
a) T(R)—Temperature as a function of Resistance: A, B, ... N (depending on the order of the polynomial)
b) R(T)—Resistance as a function of Temperature: a, b, ... n (depending on the order of the polynomial)
9.
3.7.5
Residuals are calculated for each set-point used in calculating the coefficients. Residuals are always in the same scale as the reference probe
readings. For Platinum probes, the residuals are in degrees. For Thermistor probes, residuals are in millidegrees.
Thermocouple coefficients
The following requirements must be met when calculating coefficients for
Thermocouple probes. For more information concerning the method used to
calculate the Thermocouple coefficients, see Section 3.8, Methods Used for
Calculating Coefficients.
1.
The Reference Probe readings must be in temperature (°C, °F or K).
2.
The UUT (test probe) readings must be in Voltage (mV or μV). At least
2 set-points must be used, but no more than 10 set-points can be used.
Note: The algorithm used to calculate thermocouple coefficients forces
the EMF at 0°C to 0.0µV. Therefore, using a set-point at or near 0°C when
calculating thermocouple coefficients may cause erroneous results. For
best results, use at least two set-points that are not near 0°C (more than
±5°C).
3.
The CJC readings, if used, can be in either temperature (°C or °F) or
voltage (mV or μV). If no CJC readings are needed, a scale does not
need to be selected.
Note: If CJC readings are entered in temperature, the standard thermocouple coefficients for the selected thermocouple type are used to calculate the voltage at each reading. The calculated voltages are then added to
each corresponding UUT reading before calculating characterization coefficients for the UUT. If CJC readings are entered in voltage, they are
converted to the correct scale (i.e. mV or µV) and added to each corresponding UUT reading
4.
The Thermocouple type must be selected. The following types can be

6.
Each set-point for Thermocouple probes can have an associated Cold
Junction Compensation (CJC) reading. If CJC values are not needed,
leave the CJC boxes blank. The UUT reading at each set-point is adjusted according the CJC reading for that set-point prior to calculating
coefficients. The UUT readings are not adjusted prior to calculating coefficients if values are not entered in the CJC boxes.
7.
Residuals are calculated for each set-point used in calculating the coefficients. For Thermocouple probes, the residuals are in the scale that the
UUT readings were entered in (mV or μV).

Methods used for calculating coefficients
The thermometric expressions used by this software are well known expressions and as such are described in detail elsewhere. This section touches on
some specifics as they relate to the methods used to arrive at solutions.
The coefficients for all solutions with the exception of the IPTS-68 platinum
probe are calculated using matrix methods. The IPTS-68 platinum probe solution is calculated using iteration. The solutions are either exact solutions or
overdetermined solutions depending on the number of set-points used in relation to the number of set-points required. Exact solutions result when the exact
number of set-points required for simultaneous solution of sets of equations are
used (i.e., two coefficients from two set-points). Overdetermined solutions result when more set-points are used than the unknowns require (i.e., two coefficients from three or more set-points).
3.8.1
ITS-90
The ITS-90 is expressed in terms of resistance ratio(W) vs. temperature (K)
rather than resistance (R) vs. temperature. The resistance ratio is defined as the
resistance at a temperature divided by the resistance at the triple point of water,
or:
W =
Rt
Rtpw
Because ratios are used in the ITS-90, the Rtpw is required in addition to the resistance values at the test temperatures, thus, three set-points are required to

solve for two coefficients. The example below shows a set of four equations
representing data at five temperatures ( Rtpw and resistance at four test temperatures) along with the matrix method used to solve the overdetermined set.

C′
3.8.2
Solution = Matrix 2–1 ⋅ Matrix 1
IPTS-68
IPTS-68 Like the ITS-90, the IPTS-68 is expressed in terms of resistance ratios. The denominator, however, is the resistance at the ice point (0.000C)
rather than the resistance at the triple point of water (0.010C). This software allows only exact solutions for the IPTS-68 and uses iteration or simple algebra
for the solutions.
3.8.3
Callendar-Van Dusen
The Callendar-Van Dusen expression is basically a third order polynomial with
the third coefficient (β) set to zero above 0°C. The polynomial is expressed in
terms of resistance vs. temperature in °C. It is solved by matrix methods in a
similar manner as the ITS-90 expression shown above with temperature on the
left of the equal sign and the polynomial on the right. The software allows for
overdetermined solutions. Only data above 0°C is used for solution of the first
two coefficients (α and δ). Data both above and below 0°C is used for solution
of β.
3.8.4
Polynomial and thermocouple
Polynomial solutions are arrived at using matrix methods as with the ITS-90
and the Callendar-Van Dusen. Platinum probes require polynomials expressed
in terms of resistance vs. temperature. Thermistor probes exhibit exponential
resistance vs. temperature relationships and the polynomials used are exponential expressions in terms of resistance vs. temperature. The polynomials can be
of any order up to 9th for platinum probes and up to 6th for thermistor probes.
