You must be careful especially when the slew rate setting is high or switching is performed
using large currents through parallel operation.
To prevent problems, connect the 3270 series and the equipment under test using the
shortest Twisted Wire possible to keep the voltage caused by inductance between the
minimum operating Voltage and the maximum input voltage range or set a low slew rate.
If the high-speed response operation is not required, decrease the slew rate setting.
In such settings, the value of DI /DT will be decreased, accordingly the generated voltage Will
be reduced even the inductance of load wiring can not be reduced.
In the case of DC operation also, the phase delay of the current may cause instability in the
3270 Series Control inducing oscillation. In this case also, connect the 3270 Series and the
equipment under test using the shortest twisted wire possible.
