Hioki PQ3198 - Using the Event Input Terminal (EVENT IN)

11.1 Using the External Control Terminal

Chapter 11 Connecting External Devices

By inputting an external signal to the event input terminal, you can detect external events or start and stop
recording based on the timing of input.
If using the terminal to trigger external events, you can
record the voltage and current waveforms as well
as measured values when external events occur, just as for other events.
Using this device, you can analyze power anomalie
s that occur in other electrical equipment.
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-circu
iting the terminal (active LOW) or dropping the
pulse signal (1.0 V).
Using the event input terminal (EVENT IN)
To avoid damaging this device, do not input voltages outside the range -0.5 V to
+6.0 V to the external control terminals.
