11.1 Using the External Control Terminal
178
This indicates events occurring externally that were synchronized with events occurring internally for this
device.
Usage method 1. Connect a warning device.
This is a good way to output warnings when events such an interruptions occur.
Usage method 2. Connect to the trigger input terminal of a Memory HiCorder.
This allows you to record waveforms on the Memory HiCorder when events occur on the PQ3198.
You can record between 14 and 16 waveforms on the PQ3198 when events occur. When you want to
record waveforms for a longer period of time, use the PQ3198 in parallel with a Memory HiCorder.
If an event occurs in the PQ3198, a pulse signal is output.
Use the event output terminal (EVENT OUT) and the ground terminal (GND).
Using the event input terminal (EVENT OUT)
To avoid damaging this device, do not input voltages outside the -0.5 V to +6.0 V
range to the external control terminal.
