What is the TableWare Software?

The TableWare Software 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. The TableWare Software creates a report that can be either printed to a printer or exported to an ASCII text file.

The TableWare Software 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.

New Features to Version 2

A list of new features and enhancements in version 2 of the TableWare Software follows:

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. and/or Maximum Temp. setting fell outside the recommended temperature range in °C.

5.	In version 2.2, an Overflow error sometimes occured 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 µV.

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.

10.	The maximum order for thermistor polynomials has been reduced from 9th order to 6th order. Thermistor probes do not need to be fitted above the 6th order.

Version 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. 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, the 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.

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 when using a 386 PC or some configurations of 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 problem with the calculation of coefficients and table values for ITS-90 Range 6.

2.	The resolutions that can be used now includes up to 9 decimal places. Prior to this version, the maximum number of decimal places was 7.

Version 2.1

1.	The capability to calculate Polynomial coefficients for Platinum probes using a scale other than the scale of the Reference readings. The TableWare Software 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.	The TableWare Software 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.	The TableWare Software 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 be used) the reports and tables are printed to, or which printer driver is used.

5.	The date that prints on the report and table can be set by the user.

Running the TableWare Software

After the system settings explained above have been checked, the software may be run. Double-click on the TableWare Software icon.

Every time this software is run, it checks to make sure that all of the required .DLL and .VBX files are found on your computer. If the software detects that one or more of these files has been replaced by an older file or the file is not found, a dialog appears detailing the problems found.

Every time you install any software on your computer, you should make a backup of your important files, including all files in the \WINDOWS and \WINDOWS\SYSTEM directories. Sometimes during the installation process, a file may be replaced with an older version that is not 100% compatible with the first. This older version may cause the software to perform unexpectedly or fail to run at all. Replacing a .DLL or .VBX file with a newer version does not usually cause any problems because these files are typically backward-compatible. There are, however, exceptions to this rule.

If the dialog shown above appears when you run the TableWare Software, a list of the files in question is shown in the Conflicting Files list. Select each of the files, one at a time, and read the information that appears in the bottom half of the dialog. Depending on the information given, you must decide what to do. The software may continue to run without problems, however there is no guarantee.

The .DLL and .VBX files are typically located in the \WINDOWS\SYSTEM directory. If necessary, these files can be copied to the directory to which the TableWare Software was installed to avoid conflicts. Be sure to compare the files on your computer with the list of required .DLL and .VBX files.

The Thermistor Probe Coefficients dialog is displayed when the Continue button is pressed from the Probe Information dialog and the coefficients being calculated are for a thermistor probe.

Enabled and Disabled

All options are enabled at all times.

Dialog Information

The only type of coefficients that can be calculated for thermistor probes is polynomial. Both T(R) and R(T) polynomial coefficients are calculated.

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 net 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 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 one or more.

The user is allowed to select whether or not the Steinhart-Hart method is used when the coefficients are calculated. When Steinhart-Hart is selected, the third coefficient (squared term) is set to 0.0. Please read Polynomial Requirements for more information about the Steinhart-Hart method.

The Export button saves the current raw data to an ASCII text file.

The Calculate button calculates the coefficients and displays the Coefficients and Residuals dialog.

When calculating Polynomial coefficients for either Platinum probes, the Select Calculation Scale dialog is displayed.

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 the TableWare Software. Prior to version 2.1, the TableWare Software always calculated Polynomial coefficients after converting the Reference readings to Kelvin.

Note: The TableWare Software 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.

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 net 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.

Table Options - Type and Range

Position the cursor over any item and click on the item for a description.

The Type and Range tab is displayed after selecting the Type and Range tab on the Table Options dialog.

Enabled and Disabled

All controls are enabled at all times.

Dialog Information

The Type and Range tab allows the user to select the type of table to generate and the temperature range for the table. The choices for the type of table are:

•	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/dr)" 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, the error value can be printed by selecting the "Print Error (mV)" option.

Callendar-Van Dusen Requirements

The following requirements must be met when Callendar-Van Dusen is selected as the type of coefficients to calculate for Platinum probes. Methods Used for Calculating Coefficients contains additional information.

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 coefficients 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.

Polynomial Requirements

The following requirements must be met when Polynomial is selected as the type of coefficients to calculate for Platinum or Thermistor probes. Methods Used for Calculating Coefficients contains additional information.

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 net 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 order to 6th order 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 is available in the TableWare User Guide. (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:

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.	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 Requirements


Thermocouple Requirements

The following requirements must be met when calculating coefficients for Thermocouple probes. Methods Used for Calculating Coefficients contains additional information.

1.	The Reference Probe readings must be in temperature (°C, °F or K).

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).

2.	The UUT (test probe) readings must be in Voltage (mV or µV).

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.

4.	The Thermocouple type must be selected. The following types can be selected:

a)	Type B

b)	Type E

c)	Type J

d)	Type K

e)	Type N

f)	Type R

g)	Type S

h)	Type T

i)	Type AuPt (Gold-Platinum)

5.	The temperature range for the Thermocouple type must be selected. The following ranges can be selected:

Type	Range 1	Range 2	Range 3	Other
Type B	0°C to 630.615°C	630.615°C to 1820°C	N/A	N/A
Type E	-270°C to 0°C	0°C to 1000°C	N/A	N/A
Type J	-210°C to 760°C	760°C to 1200°C	N/A	N/A
Type K	-270°C to 0°C	0°C to 1372°C	N/A	N/A
Type N	-270°C to 0°C	0°C to 1300°C	N/A	N/A
Type R	-50°C to 1064.18°C	1064.18°C to 1664.5°C	1664.5°C to 1768.1°C	-50.0°C to 1768.1°C (using extrapolation)*
Type S	-50°C to 1064.18°C	1064.18°C to 1664.5°C	1664.5°C to 1768.1°C	-50.0°C to 1768.1°C (using extrapolation)*
Type T	-270°C to 0°C	0°C to 400°C	N/A	N/A
Type AuPt	0°C to 1000°C (8th order Canadian Polynomial)	0°C to 1000°C (9th order American Polynomial)	N/A	N/A

*Selecting this range allows TableWare to automatically select the appropriate reference function to use to calculate the EMF at each temperature. Selecting one of the other ranges forces TableWare to use the reference function for the selected range to calculate the EMF for ALL temperatures.

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.	For Thermocouple probes, the residuals are in the same scale as the UUT readings (µV or mV). Residuals are calculated for each set-point used in calculating the coefficients.

8.	The following Thermocouple coefficients are calculated: (The values of these coefficients are the sum of the standard coefficients and the deviation calculated using the selected set-points.)

a)	c1

b)	c2

9.	The following standard Thermocouple coefficients are also produced unaltered:

Type	Range 1 Coefficients	Range 2 Coefficients	Range 3 Coefficients	Other (see above)
Type B	c3...c6	c0, c3...c8	N/A	N/A
Type E	c3...c13	c3...c10	N/A	N/A
Type J	c3...c8	c0, c3...c5	N/A	N/A
Type K	c3...c10	c0, c3...c9	N/A	N/A

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 over-determined 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). Over-determined solutions result when more set-points are used than the unknowns require (i.e., two coefficients from three or more set-points).

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 = R(t)/R(tpw)

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 over-determined set.

A
B
C
An exact solution (i.e., two unknowns in two equations) would be arrived at with the following operation:

C′
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 (0.000°C) rather than the resistance at the triple point of water (0.010°C). This software allows only exact solutions for the IPTS-68 and uses iteration or simple algebra for the solutions.

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 over-determined 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.

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. The software allows for over-determined solutions. Thermocouple probes require polynomials expressed in terms of µV vs. temperature.

Remarks The selected temperature range for generating a table exceeds the recommended range for the selected type of coefficients. These ranges are detailed in the Table Temperature Range chart. Temperatures below the minimum temperature and above the maximum temperature will be extrapolated and may not necessarily be accurate. If the selected minimum and maximum temperatures are too extreme, the algorithms used to calculate the table values may not produce correct results. The TableWare Software has been thoroughly tested over the recommended temperature ranges and found to produce correct results.
