12.1 Device profiles
12.1.1 Power circuits
Main circuits without dynamic frequency changes. The universal profile is suitable for all systems
primarily with constant power frequencies and extraneous DC voltages. When using inverters and
dynamic frequency control, select Inverter > 10 Hz or Inverter < 10 Hz.

12.1.2 High capacitance
For systems with high leakage capacitances, e.g. ship applications, the impact of leakage capaci-
tances on the measuring result can be significantly reduced by selecting this profile.
