4.2 Alarm Output
88
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] ).
No alarm signal or alarm sound is output after measurement stops.
External alarm output requires connection to the external control terminals.
Refer to “Chapter 9 External Control” (p. 157) for details.
Select alarm input channels on the
[CH] screen, and specify alarm criteria on
the [Trig & Alm] screen.
4.2 Alarm Output
Alarm Criteria
Channel alarm status (CH 1 to CH10, P 1 to P
4, and W 1 to W10)
• Yellow*: alarm criteria are satisfied
• Green: alarm criteria are not satisfied
*. When
[Hold Alarm] is enabled (set to
[On] ), the indicator remains yellow because
the criteria remain satisfied (until measure-
ment is finished).
The
[Buzzer] alarm sound can be set to on or
off. When [AllDsp] is set to [On] , the detected
waveforms for CH 1 to CH10 and P 1 to P 4
set to the alarm source will also be displayed
(The detected waveforms for W1 to W10 are
not displayed).
Alarm output status (ALM)
• Red: alarm signal output active
• Green: alarm signal output inactive
