4.6.10.11 DISABLED FUNCTIONS IN I3-PARALLEL CURRENT MODE.
Individual current phase angle adjustment is disabled in I3-PARALLEL current mode since the phase
angles of all currents being paralleled should be the same for parallel operation.
Calibration functions are also disabled in I3-PARALLEL current mode since there’s no calibration
necessary for current in this current mode.

FAULT MODES
The fault mode selects the type of fault to be simulated. The fault mode is a combination of the FAULT
PHASE and FAULT TYPE selections.
The fault mode controls also are used to select the voltage(s) to be measured, displayed, adjusted, and to be
used in phase angle measurements. In the I3 current mode, the fault mode also sets the current path from the
[I3 OUTPUT]. In I3-WYE current mode, the fault mode also controls the three-phase current (see Sections
9.4.1 and 9.4.2).
The fault mode selector simplifies voltage adjustment by allowing simultaneous adjustment of one or more
voltages, and automatic selection and display of the voltage of interest.
