If necessary, from the Main menu press F1 “Measure.”

Press F2 to change to the “Analyzer Channel Status” menu.

Or, from the Main menu press F2 to the “Analyzer Channel Status” menu.

From the “Analyzer Module Status” menu an additional submenu is available for “Power supply voltages..." to check the various volt- age levels in the analyzer.

Press the ↵ or → key to access the “Power supply voltages..." display screen. The toler- ance for these voltage is ±10% of nominal.

Press the F4 (Back…) button to return to the “Analyzer Module Status” menu or the F1 (Measure) button to return to the “Measure” display screen.

From the “Analyzer Module Status” menu, press the F2 (Back…) button to go to the “Main Menu” or press the F1 (Measure) but- ton to return to the “Measure” display screen.
