5. To test the DUT under Unbalance three-phase mode, you can connect the
communication interface (GPIB/USB/RS232/LAN/CAN/RS485) of the host A
to the PC. Please refer to 2.5 Connecting the Interface.
Set the three-phase voltage value and the angle difference of the three
phases through PC. For specific setting instructions, please refer to "IT-
M7700 Programming and Grammar Guide".
Revert to single mode
1. Press the [Link] key on the front panel of master A to cancel the three-phase
synchronization mode.
2. Set each of the three instruments to single mode.
