Battery operation for use
in every field location.
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.

The 3286 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.

❏ External output of data

check
The 3286's three-phase power measurement 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).
❏ Check power supply fluctuations
Max. and min. value displays
Using the record function, it is
possible to check the amplitude of
fluctuations.

The 9636-01 can transfer 3286 measurement data to a
personal computer, and supports efficient data handling.
