Simulation - NF DP420LS Instruction Manual

11.19 Simulation

This allows you to simulate power line abnormalities, such as blackout, voltage rise, voltage drop,
abrupt phase change, and abrupt frequency change. It can be used only for AC, sine wave, and
AC+DC-INT. Note that it does not support IEC or other standards test. When performing the tests
specified by the standards, use appropriate peripheral equipment. In the polyphase system, only
the balanced mode is available.
