Weibull++ Life Data Folio

Transfer Data to Weibull++

You can transfer data in an ALTA life-stress data folio to a Weibull++ life data folio in order to perform life data analysis on your accelerated test data.

To transfer the data, click the Transfer Data to Weibull++ icon on the control panel.

Then select how you want to transfer the data:

In the Weibull++ free-form data sheet, the X-axis represents the stress intervals and the Y-axis represents the unreliability (as a percentage ) for each interval, as shown in the following example. The product's use stress level is 356 K, and the maximum stress level used in the test is 426 K. Thus, the X-axis values range from 356 to 426. If the specified time was 1,000 hours, then, according to the first row of this data sheet, the product has a probability of failure of 31.57% at 1,000 hours at a stress level of 356 K. If you wish, you can calculate this data to further analyze the relationship between stress level and unreliability.
