Checking the instrument before use
Before using the instrument, check the instrument for any damage that may have been sustained
while in storage or transit, inspect it, and verify that it is operating properly. If you discover any
malfunction or damage, contact your authorized Hioki distributor or reseller.
DANGER
Damage to voltage cords or the instrument may result in electric shock. Check
voltage cords for worm insulation and exposed metal before use. If you nd
damage, replace the cords with those specied by our company. Failure to do so
may result in electric shock.
WARNING
To prevent electric shock, verify that the white or red portion of the cable
(insulation layers) are not exposed. If any color is visible from the inside of the
cable, do not use the instrument.
Installation
Installing the instrument in inappropriate locations may cause a malfunction of instrument or may
give rise to an accident. Avoid the following locations.
WARNING
• Exposed to direct sunlight or high temperature
• Exposed to corrosive or combustible gases
• Exposed to water, oil, chemicals, or solvents
• Exposed to high humidity or condensation
• Exposed to a strong electromagnetic eld or electrostatic charge
• Exposed to high quantities of dust particles
• Near induction heating systems (such as high-frequency induction heating
systems and IH cooking equipment)
• Susceptible to vibration
CAUTION
• Do not place the instrument on an unstable bench or inclined surface. Doing so may
cause the instrument to fall off the surface or to fall over, resulting in bodily injury or
equipment damage.
• Do not use an uninterruptible power supply (UPS) or a DC-AC inverter that produces
rectangular waves or pseudo-sine-wave output to power the instrument. Doing so
may damage the instrument.
11
Operating Precautions
Instrument placement
• Place the instrument right-side up.
• Do not block the instrument’s air vents.
• Leave at least 20 mm between the instrument’s air vents and surrounding surfaces.
See “1.3 Part Names and Functions” (p. 19).
Handling of the instrument
At least 20 mm on all sides
DANGER
To prevent electric shock, never remove the instrument’s enclosure. There are
high-voltage and high-temperature parts inside the instrument.
CAUTION
• To prevent damage to the instrument, avoid exposing it to vibration or mechanical
shock when transporting or otherwise handling it. Exercise particular care not to drop
the instrument.
• If the instrument malfunctions or displays an error during use, consult
“12 Troubleshooting” (p. 255) and then contact your authorized Hioki distributor or
reseller.
• Carry the instrument using its handle after disconnecting all cords and removing the
USB ash drive.
• Do not press down on the touch panel with excessive force or use hard or sharp
objects to press down on the touch panel. Doing so may result in equipment damage.
This instrument may cause interference if used in residential areas. Such use must be avoided
unless the user takes special measures to reduce electromagnetic emissions to prevent
interference to the reception of radio and television broadcasts.
12
Cord and current sensor handling
• Always connect voltage cords and current sensors to the secondary side of a
circuit breaker. The secondary side will be protected by the breaker in the event
of a short. Do not measure the primary side of a circuit breaker as it will carry a
larger current, increasing the amount of damage in the event of a short-circuit.
• When using the instrument, always use the designated power cord. Use of a
power cord other than the designated cord may result in re.
• Connect current sensors and voltage cords to the instrument before connecting
them to a live measurement line. Observe the following precautions to prevent
short-circuits and electric shock:
• Do not place the metal part of the tips of voltage cord clips across two
measurement lines at the same time. Never touch the metal part of the tips of
voltage cord clips.
• When a current sensor is in the open position, do not place the metal part
of its clamp tip across two measurement lines at the same time or use the
sensor on a bare conductor.
• Do not connect voltage cords unnecessarily.
Operating Precautions
DANGER
• To prevent short-circuit or bodily injury, use current sensors with circuits
whose voltage is less than or equal to the sensor’s maximum rated input-toground voltage. Do not use current sensors with bare conductors. (For more
information about a current sensor’s maximum rated input-to-ground voltage,
refer to its instruction manual.)
WARNING
• When using an AC/DC Current Sensor such as the CT6862, it is necessary to
cut the measurement line in order to route it through the sensor. To prevent
an electric shock or short-circuit, turn off all equipment before connecting the
sensor.
• To prevent an electric shock or short-circuit, use the designated voltage cords
to connect the measurement lines to the instrument’s voltage input terminals.
CAUTION
• To ensure safety, use only voltage cords designated by our company.
• To prevent a break in instrument wiring, grip the plug (not the cord) when unplugging
the power cord from an outlet or disconnecting it from the instrument.
• Exercise caution as conductors being measured may become hot.
• To avoid damaging cord insulation, do not step on cords or allow them to be pinched
between other objects.
• If a voltage cord melts, its metal conductor may be exposed. Do not use a cord whose
metal conductor is exposed. Doing so may result in electric shock, burns, or other
injury.
• Do not drop current sensors or subject them to mechanical shock. Doing so may
damage the core joint and adversely impact measurement. When disconnecting a
connector, always release the lock and then grip the connector to pull it out. Pulling
on connectors with excessive force before releasing the lock or pulling on cables will
cause damage to connectors. (p. 36)
• Do not connect or disconnect connectors while the instrument is on or while a sensor
is clamped to the conductor being measured. Doing so may damage the instrument or
current sensor.
13
Operating Precautions
Handling of the L6000 Optical Connection Cable
WARNING
When connecting an L6000 Optical Connection Cable that is already connected
to an operating optical output to the instrument, never look directly at the tip of
the cable or observe it with a device such as a magnifying glass. Doing so may
adversely affect your eyes or damage your vision.
CAUTION
• When connecting an L6000 Optical Connection Cable to the instrument, exercise care
to ensure that there is no dirt or dust in the optical connector. In particular, exercise
caution concerning the end face (ferrule). Accurate measurement may be impossible
if the cable is connected while there is dirt or other foreign matter on the face, or if the

1.1 Product Overview
The PW6001 series of power analyzers comprises models with simultaneous measurement capabilities
for targets ranging from one 1-phase/2-wire circuit to two 3-phase/4-wire circuits, enabling them to
accommodate a variety of measurement lines. Variants offer from one to six channels.
For use in the development and evaluation of increasingly efcient inverter motors
• The PW6001 can perform high-precision, high-stability, wideband inverter power measurement that is highly
reproducible.
• The instrument can perform electrical angle measurement, which is a necessary part of motor analysis.
• When connected to a high-precision torque meter and encoder, the instrument can measure motor efciency.
For use in the development and evaluation of alternative energy technologies,
including solar power, wind power, and fuel cells
• The PW6001 can simultaneously measure AC power and DC power at a high level of precision and calculate
efciency.
• The instrument can measure power drawn from the grid, power sold to the grid, and power by consumption/
generation by means of DC mode and RMS mode current and power integration.
1
Overview
For use in the measurement of high-frequency power in wireless power feeds
and DC/DC converters
• The PW6001 can measure power at frequencies of up to 1 MHz.
• The instrument can measure and analyze harmonic distortion of switching waveforms at frequencies of up to
300 kHz.
1.2 Features
Simultaneous measurement of multiple circuits incorporating various types
of power lines (p. 41)
• For 3-phase/3-wire circuits, users can select a Hioki model 3193-compatible 3V3A connection or a Hioki
model 3390-compatible 3P3W3M connection in addition to the two-wattmeter method. The 3P3W3M
connection is particularly well suited to measuring power with inverter motors that have high-frequency leak current.
High accuracy and highly stable circuitry for high measurement reproducibility (p. 75)
The instrument delivers best-in-class basic accuracy and DC accuracy for active power and therefore provides
support for DC/AC conversion efciency with high-accuracy measurement performance.
High-bandwidth, high-speed opto-isolated sampling
• The PW6001 can measure increasingly high-speed switching waveforms accurately thanks to wideband
voltage and current input circuits (DC, 0.1 Hz to 2 MHz) and 5 MS/s, 18-bit high-speed, high-resolution
sampling capability.
• Thanks to its use of voltage inputs that use new optical devices to implement isolation with a high dielectric
strength, the instrument delivers a CMRR of 80 dB (at 100 kHz), enabling it to aggressively reject highfrequency common-mode noise when measuring inverters.
Support for a variety of current sensors (p. 36)
• In addition to conventional power measurement sensors, the PW6001 supports wideband current probes
designed for use with megahertz-order frequencies.
• The instrument ships standard with a power supply for 3270 series clamp-on probes.
17
Features
New functionality to take full advantage of current sensor performance (p. 125)
The instrument’s phase compensation calculations can correct current sensor’s high-frequency phase
characteristics.
Complete six-channel + dual mode harmonic analysis function (p. 69)
The PW6001 supports simultaneous harmonic analysis for all channels. By performing simultaneous harmonic
analysis for multiple circuits with different frequencies, the instrument can perform simultaneous harmonic
analysis for both the primary and secondary sides of an inverter.
Waveform observation functionality on par with that of an oscilloscope (p. 93)
The PW6001 can record waveforms of up to 100 sec. in duration (10 kS/s sampling) or 10 sec. in duration (at
100 kS/S sampling) thanks to its large waveform storage memory (1 Mword × 6 voltage/current channels).
Standard USB ash drive support and large internal memory (p. 139)
• Thanks to its large, 64 MB internal memory capacity, the PW6001 can continuously record data for numerous
parameters even when using a high-speed interval.
• Data can be saved directly on a USB ash drive, screens can be copied to a USB ash drive, and data can
be copied from the internal memory to a USB ash drive.
Easy-to-understand touch panel and key operation (p. 19)
• The PW6001 can be controlled using either dedicated hardware keys or an easy-to-understand touch panel.
• Comments can be entered on the touch panel when saving screen copies and measurement data.
Robust motor analysis functionality (option) (p. 182)
• When fed output from a torque meter and tachometer, the PW6001 can measure motor power and motor
efciency.
• The instrument supports A-phase/B-phase pulse output from a rotary encoder as rotation input and can
detect the direction of rotation.
• It also supports Z-phase output from the encoder and can measure the motor’s electrical angle.
• A single PW6001 can simultaneously accept two sets of torque and RPM input, leveraging its six channels of
input to allow simultaneous analysis of two motors.
• The instrument can simultaneously display either the torque waveform or the encoder pulse waveform along
with voltage and current waveforms.
• Since all inputs are functionally isolated, they can be used for two-channel voltage measurement at up to
±10 V or pulse waveform measurement across four channels at up to 1 MHz.
High-speed D/A output with waveform capability (option) (p. 173)
The PW6001 incorporates 20 channels of D/A output, enabling it to generate analog output for 20 userselected measurement parameters.
• When using waveform output mode, voltage and current waveforms for the number of channels with which
the instrument is equipped are output in order at 1 MS/s and 16 bits. Safe, isolated voltage and current
waveforms can be input to another waveform measuring instrument for analysis.
High-performance remote synchronization function using optical ber (p. 169)
• Optical ber can be connected to the synchronization interface to enable synchronized measurement at
multiple locations with different instrument power supply potentials.
• Up to two instruments separated by up to 500 m can be synchronized to perform measurement.
Dedicated communications application software (downloadable from Hioki’s
website) (p. 189)
