Calculation of Total Power
Accura 2300S supports two methods for calculation of the total power based on power per phase. One
is to calculate the total power based on the vector sum of 3-phase apparent power. And the other is to
calculate the total power based on the arithmetic sum of magnitudes of 3-phase apparent power
vectors. Refer to
「
Chapter 5 Measurement >Three-Phase Power Measurement
」
for details.

Power Factor Sign
The sign of the power factor is determined according to the sign of active power, and it makes it
possible to find out whether power has been received or delivered. However, when displaying the
power factor only as an absolute value, configure the sign as

」
. The available max/min value of the
power factor is the max/min value of the absolute value of the power factor regardless of the PF sign
settings.
