Always indicates the sum of the three phases:
+P
positive active energy direction (imported from power company)
-P
negative active energy direction (exported to power company)
+P
-P
positive active energy direction, but negative active energy
direction of individual phases (arrow -P flashes); only in three-
phase four-wire circuit (only with magnitude summation).

The reactive no-load indication (a diamond) shows that the kvarh registers
have entered anti-creep mode. No energy is flowing through the meter (no
reactive energy direction indicator displayed).
The active no-load indication (a circle) shows that the kWh registers have
entered anti-creep mode. No energy is flowing through the meter (no active
energy direction indicator displayed).
