Selecting auto scale automatically adjusts the paste scaling value for the current
site, to cause the value of paste present, on the pad currently selected in the
inspection result list, to be reported as 100%. The inspection results window is
updated accordingly. If the calculated value for paste scaling falls outside the
range of allowable values, an error window is displayed and the paste scaling
value is set to the limit nearest the calculated value. However, if the currently
selected paste present value is zero, no adjustment of the paste scaling value
takes place and an error window is displayed. A prompt is displayed giving the
new scaling factor value each time it is changed. The auto scale button is only
present if board inspection is being performed.
