4.7The Analyze Function

Normally, all of the functions automatically switch back to the Analyze function when they have completed their assigned operations. Pressing the Escape button in many cases also switches the analyzer back to the Analyze function. Alternatively, if you leave your analyzer on MAIN MENU screen within 5 seconds without touching any key, it will automaticaly return to analyze

function. If the analyzer is in subfunction mode, in most cases, it will automaticaly return to analyze mode within 10 minutes.

The Analyze function screen shows the impurity concentration and the application gases in the first line, and the range in the second line. In the lower right corner, the abbreviation Anlz indicates that the analyzer is in the Analyze mode. If there is an * before the Anlz, it indicates that the range is linearized.
