1. Communication test
2. to 5. No function
6. Functions for determining
incorrect wiring
*Note: The function cannot determine all incorrect wiring. If both a voltage input and a current input are
incorrectly wired, a different pattern may be displayed.

Use this for checking with the host system.
①Pattern display for incorrect wiring
When either a voltage input or current input is incorrectly wired, this
function automatically determines incorrect wiring and displays its
part on the screen. It is easier to find out the incorrect part and
useful to check the connection. *Note
②Support display for determining incorrect wiring
This function displays a current phase angle, a voltage phase
angle, and active power, voltage, and current value of each phase.
By checking each display and 9.2 A List of Examples for
