Hioki 3196 - Event Input Terminal (EVENT IN)

8.2 Event Input Terminal (EVENT IN)
137
By inputting a signal to the event input terminal externally, you can
make the 3196 determine that an external event has occurred when
that event was input. Similar to other events, you can record the volt-
age and current waveforms, and the measurement values of external
events.
Using this device, you can analyze power anomalies that occur in
other electrical equipment.
Signal input methods
Short-circuit the terminal or input a pulse signal.
Use the event input terminal (EVENT IN
) and the ground terminal
(GND).
You can control the event input terminal by short-circuiting the terminal
(active LOW) or dropping the pulse signal (2.5 V).
