The measurement is displayed on screen.
NOTE: 3-phase power on a balanced 4-wire network can also be measured by
proceeding in the same way, or by proceeding as for the measurement on a
single-phase network, then multiplying the value by three.
Four Quadrant Diagram 3.10.3
To correctly determine the sign of the active and reactive powers, refer to the
diagram below, which determines:

positive active power (W) = power consumed

negative active power = power generated

reactive power (var) and active power of the same sign = inductive power

reactive power and active power of opposite signs = capacitive power
