Frequency

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.

1000 Hz max.

Harmonics

●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.

Helpful battery capacity check

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.

Cord length:

approx 2m

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.

Since there is no integration function, it is not possible to measure total energy consumed (Wh).
