Greater accuracy for
standby power
The PW3335 Power Meter delivers a
range configuration that lets you measure
extremely low power levels with a margin
to spare. Accuracy can be set from 10 μA
and up for current, and 0 W and up for
effective power. Perfect for measurements
acco r d i n g t o I E C 6 2 3 01 and other
standards.
Peak value of up to 600%
of the range, supporting
crest factor of 6
Power factor effects of
no more than ±0.1% f.s.
Current waveforms in the switching power
supply or at the primary-side of inverters
become steep and often exceeds the
fundamental range, preventing them from
being accurately measured. The PW3335
resolves these issues by offering a crest
factor of 6, allowing it to measure accurately
even when the waveform peaks are high
relative to its range.
The effective power value may be affected
in situations with low power factors, such
as measurement of standby power or
unloaded operation of transformers and
motors. The PW3335 reduces the power
factor effect to less than a half of that
available in legacy models.
Power data and harmonic
data — all measured
simultaneously
Built-in harmonic
measurement
All measurement data are internally
processed in parallel simultaneously.
Even when waveforms have mixed
AC/DC components – half-wave
rectification waveforms for example – the
individual components can be measured
simultaneously. The PC communication
application further enables 180 or more
measurement parameters to be acquired
simultaneously.
Example of
distorted waveform
containing harmonic
component
The PW3335 measures harmonics up
to the 50th order. Use it for evaluation
and development of power sources for
home appliances and other electrical
equipment. Simultaneously display the
effective voltage and total harmonic
distortion (THD) on the screen. For THD
computation, any maximum harmonic
order can be specified.

Diverse and Powerful Functionality
Measure power in accordance with
international standards
Measure integral power of equipment that operates
intermittently or has a large power variation
The PW3335 is engineered to comply with important international
standards, including IEC62301 for electrical power consumption in
standby mode and the ErP Directive or Energy Star standard. It can also
be used to find the special parameters required by the standards – such
as THD, CF, and MCR.
Time-averaged effective integral power
Use this feature to measure the power of equipment that operates intermittently or is under
cycle control. Average power is calculated from the integral value of the fluctuating power.
THD (total harmonic distortion)
Indicates the total harmonic components in an AC waveform.
CF (crest factor)
Also known as the peak-to-rms ratio, the ratio of the waveform's peak
value to its effective value.
MCR (maximum current ratio)
Evaluation index of the current, calculated from the crest factor and
the power factor.
Example of intermittent operation
Example of cycle control
Auto-range integration
A function whereby the device jumps automatically to the optimal current range for the
consumed current as it measures and integrates the values. Power integration can be
carried out on separate ranges, enabling measurements for individual modes in equipment
that has fluctuations in power levels.

The PW3335 can output measurement
values to a data logger, Hioki Memory
HiCorder or similar, via voltage signals.
The power meter is also built in with
functions for outputting the high-speed
level of each successive fundamental
wave cycle*, in addition to instantaneous
waveform output and level output, and
provides in-depth analysis of powerconsuming equipment such as cutting/
grinding tool monitoring equipment.
PC communication
software
By using the bundled PC application,
you can control the power meter from a
PC without needing to code your own
communication program. The software
enables you to save data to the PC, display
waveforms, and perform efficiency
calculations*, etc.
Compatible with LAN, RS-232C, GP-IB
* For voltage and current, cycle-by-cycle updating
is possible only with an input of 45 to 66 Hz.
*Two or more PW3335s are necessary in order to
carry out efficiency computation.
Up to 8 units of
simultaneous control
Pair with current sensors
delivering a maximum
accuracy of ±0.26% to
measure 30 A and up
Use the simultaneous control feature for
measuring input/output efficiency of the
power source equipment, for making
comparisons between multiple equipment,
or for simultaneous parallel testing of
production lines and achieve measurement
with guaranteed synchronization. Efficiency
computation is also possible in conjunction
with PC software. Synchronization with
both the Hioki PW3336 and PW3337 Power
Meters is also supported.
(PW3335-03, PW3335-04)
You can input up to 5000A AC with the use
of an optional current sensor. Using Hioki
AC/DC high-accuracy pull-through sensors
will enable precise measurement with
maximum accuracy of ±0.26%.

Value monitoring
The Value monitoring function displays the PW3335's measurement values on the
PC screen. You can freely select up to 64 values, such as voltage, current, power, and
harmonics.
Waveform monitoring
This function enables you to monitor the voltage, current, and waveforms measured by
the meter right on the PC screen.
Meter setting
The application also enables you to configure the connected PW3335 from the PC screen.

When using multiple PW3335s, computation of the input/output efficiency of a power
converter and similar operations are supported. This feature can be used to synchronously
control up to 8 meters – including Hioki PW3336 and PW3337 series units – connected
together with synchronous control cables.
