Power Tech (tm) Spring Tester Software Upgrade for Windows 98/Me/NT/XP/2000/Vista

Computer Program and USB Interface to Use Performance Trends' Valve Spring Tester v1.1 Software with Power Tech's Spring Tester, Part Number SPV11C-DM

Our Valve Spring Tester software can also work with Power Tech's Compu-Spring Tester with our USB interface shown below.

  Our software offers several enhancements over the Compu-Spring software, including:

Much improved repeatability.
Additional calculations.
Many more Report and Graph features, including overlay graphs.
Much enhanced print features and quality for reports and graphs.

 

The 2 printouts below show 16 tests of the SAME SPRING tested with a Power Tech Spring Tester, first using the standard Power Tech Compu-Spring software, and then using our Valve Spring Tester v1.1 and USB interface.  Because the exact same tester was used, the difference in the results is entirely due to the improved accuracy in our software.

Comparison Table of Power Tech (tm) and Performance Trends Results

  Range in Spring Rate Range in Seated Force Range in Open Force Range in Bind Height
Power Tech 8  lbs 2  lbs 5  lbs .025 inches
Performance Trends 3.1  lbs 1.6  lbs 1.4  lbs .002 inches

Comments:

In all results measured, the Performance Trends software produces much more repeatable results.
The Performance Trends report shows averages and ranges automatically in the results.
The Performance Trends report also includes the spring height which produces a particular force (in this case 200 lbs).
We tried to print the Power Tech report directly to Adobe Acrobat (tm) to produce a higher quality picture, but it seemed to be incompatible.  That may be to its "DOS like" printout.  The Power Tech software does seem to work much like a DOS program.
Power Tech reports its results only to the nearest pound (lb) and .005 inches, where Performance Trends reports it to the nearest 0.1 lb and .001 inch.
We believe the Power Tech report above is the only output available from the Power Tech software.  No other types of graphs or reports are possible.

We are not saying that some users may not like the layout or operation of the Power Tech software.  Software with less features is typically easier to use.  We're just offering our software to those who want more features and improved accuracy.

 

What You Need:

Power Technology PT-200 spring tester (either DOS or Windows, with parallel printer or USB interface), and computer with Windows 98, Me, XP, 2000, NT or Vista with a USB port.

 

What You Get:

The part number  SPV11C-DM  package comes with program CD (with user manual in PDF format on the CD) and USB Interface.  The USB interface does not require a separate power supply.  It has one lead which plugs into your Power Tech tester and another lead which plugs into your computer's USB port.
