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.
HRM: switches to the harmonic display.
START/STOP: Starts and stops integration; resets integrated values.
HOLD: Switches between the hold, maximum value, and minimum
value displays.
SHIFT: Press to access functions shown in blue.

Display Description
Allows you to measure three 1-phase/2-
1P2W×3
wire circuits. (PW336: Allows you to
(PW3336: 1P2W×2)
measure two such circuits.)
Measures a 1-phase/3-wire circuit with
1P3W&1P2W CH1 and CH2. The PW3337 can simul-
(PW336: 1P3W only) taneously measure a 1-phase/2-wire
circuit with CH3.
Measures a 3-phase/3-wire circuit with
CH1 and CH2 and measures active
3P3W&1P2W power
(PW336: 3P3W only) method. The PW3337 can simultane-
CH(3)
ously measure a 1-phase/2-wire circuit
with CH3.
CH(2) CH(1)
Display Description
Measures a 3-phase/3-wire circuit with CH1 and CH2 and
measures active power using the two-power-meter
3P3W2M 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.
Measures a 3-phase/3-wire circuit with connections for all
3V3A line voltages and phase currents and measures the
active power using the two-power-meter method.
Measures a 3-phase/3-wire circuit. Uses the same con-
using the two-power-meter nections as the 3V3A wiring mode but converts line volt-
3P3W3M
ages into phase voltages by means of vector calculations
and displays the results.
3P4W Measures a 3-phase/4-wire circuit.
