7.4 Using the External Control Terminals
The external control terminals can be used to signal the instrument of the occur-
rence of an event with an external input trigger signal, or to signal the detection
of an event by the instrument with an output signal.
To avoid damage to the instrument, do not apply voltage outside the
range of -5 V to +10 V (EVENT IN
terminal), or 0 to +50 V (EVENT OUT
terminal).
External event inputs are recorded as EXT events.
During a measurement startup, measurement stop, and manual
event, signals are also recorded as EXT events.
Pressing the [ESC] and [EVENT] keys simultaneously generates
a manual event.
Event output terminal (EVENT OUT)
The instrument provides an external signal
when it detects an anomaly.
The event output terminal can be connect-
ed to the trigger input terminal of a wave-
form recording instrument such as a
Memory HiCorder to control waveform re-
cording by the timing of event occurrence.
Event input terminal (EVENT IN)
An external device can be used to con-
trol the timing of analysis of anomalies.
The event input terminal can be con-
nected to an anomaly detecting instru-
ment such as an overcurrent relay to
control the timing of this instrument’s an-
alyzing functions by externally detected
events.
