Lag/Lead

display
Uses the sign of reactive power Q (fundamental wave reactive
power).
Positive opposite sign
: Lag
Negative opposite sign : Lead
Output data
For SD memory card and internal memory output data, the polarity
indicates lag/lead.
Lag : Positive
Lead: Negative
Power factor (PF, PF/Q/S calculation selection: fundamental calculations)
This power factor PF is defined as the displacement power factor DPF.
Active energy (WP), Reactive energy (WQ)
Measurement
method
Active power values are integrated separately for consumption and
regeneration from the start of recording.
Reactive power values are integrated separately for lag and lead
from the start of recording.
See: "Electric energy" (p. 184)
