The 3286-20 provides the following 2 types of power factor measurement. If
the waveform includes harmonic distortion, there will be a difference between
the two measurement values, and the method must be selected accordingly.
●Power factor derived by phase discrimination (cos ø):
1ø Power Factor meter and 3ø Power Factor meter mode
From the phase information for the fundamental frequency component, cos ø is
calculated. This is suitable for assessing the quality of a power supply.
●Power factor (effective value power factor)
derived from effective power ÷ apparent power: 1ø Power meter mode
This is calculated from the power value including harmonic components
(effective power ÷ apparent power). This is suitable for evaluating the
performance of standalone load equipment and similar cases.
* It is not possible to calculate the effective power factor of a three-phase line.

Whenever the unit is powered on, and
while the record function is operating, the
battery capacity can be checked to avoid
battery exhaustion during measurement.

The 3286-20's three-phase power measurement method calculates and
displays the power values for a sine wave input at 50/60 Hz, assuming
it is balanced and there is no distortion. Accurate measurement is not
possible on a three-phase line if it is not balanced, for example when
controlled by an inverter or thyristor.
Cord length:
approx 2m
Since there is no integration function, it is not possible to measure total energy consumed (Wh).
❏ Check power supply fluctuations
Max. and min. value displays
Using the record function, it is
possible to check the amplitude of
fluctuations.
