10.2 TEST CALCULATIONS 10.2.1 DESCRIPTION
The following is the user input quantities and their ranges. Each test does not use all the quantities. The default values are
used for only the first test dialog box displayed for each new test.
10.2.2 ENTERING INPUT QUANTITIES
When the user clicks on a Select button from a TestC
alculations dialog box, the Enter Value dialog box is displayed. This
dialog box has two modes, one is to enter a value for a continuous range of values and the other is to select a value from a
list of values. Select the Help button from the Enter Value dialog box. A help screen is displayed describing how to use this
dialog box.
