You can enable beep tones and an alarm output signal (for external use) for each
input channel by setting its alarm criteria. You can also view alarm output status on
screens that display numerical values ([Wave+Value], [Value+Cmnt] and [Value]).
External alarm output requires connection to the external control terminals.
See Chapter 9, "External Control" (p. 129) for details.
Select alarm input channels on the [CH] screen, and specify alarm criteria on
the [Trig & Alm] screen.
