Thank you for purchasing the HIOKI PW3336, PW3336-01, PW3336-02,
PW3336-03, PW3337, PW3337-01, PW3337-02, or PW3337-03 Power
Meter. This Measurement Guide introduces basic measurement methods
to individuals using the instrument for the first time. Be sure to review the
Instruction Manual before using the instrument.

Description
1P2W×3
(PW3336: 1P2W×2)
Allows you to measure three 1-phase/2-
wire circuits. (PW336: Allows you to
measure two such circuits.)
1P3W&1P2W
(PW336: 1P3W only)
Measures a 1-phase/3-wire circuit with
CH1 and CH2. The PW3337 can simul-
taneously measure a 1-phase/2-wire
circuit with CH3.
3P3W&1P2W
(PW336: 3P3W only)
Measures a 3-phase/3-wire circuit with
CH1 and CH2 and measures active
power using the two-power-meter
method. The PW3337 can simultane-
ously measure a 1-phase/2-wire circuit
with CH3.

Description
3P3W2M
Measures a 3-phase/3-wire circuit with CH1 and CH2 and
measures active power using the two-power-meter
method. Calculates line voltage and phase current, which
are not actually measured, using vector calculations and
displays the result as the CH3 voltage and current.
3V3A
Measures a 3-phase/3-wire circuit with connections for all
line voltages and phase currents and measures the
active power using the two-power-meter method.
3P3W3M
Measures a 3-phase/3-wire circuit. Uses the same con-
nections as the 3V3A wiring mode but converts line volt-
ages into phase voltages by means of vector calculations
and displays the results.
3P4W
Measures a 3-phase/4-wire circuit.
Press
to select the wiring mode.
