CAUTION
• Observe the following to avoid damage to the instrument.
• Use the battery pack in an ambient temperature range of 0°C to 50°C and charge it in
an ambient temperature range of 10°C to 35°C.
• If the battery pack fails to nish charging within the stipulated time, disconnect the AC
adapter to stop charging and contact your dealer or Hioki representative.
• Consult your dealer or nearest service station should liquid leaks, strange odor, heat,
discoloration, deformation and other abnormal conditions occur during use, charging
or storage. Should these conditions occur during use or charging, turn off and
disconnect the instrument immediately.
• Do not expose the instrument to water and do not use it in excessively humid
locations or locations exposed to rain.
• Do not expose the instrument to strong impact and do not throw it around.
• Heed the following instructions to avoid battery pack performance drop or leakage.
• The battery pack is a consumable. If you are able to use the instrument for only a limited period of time
despite the battery pack being properly charged, the battery pack’s service life is at an end, and it should be
replaced.
• When a battery pack that has not been used for a long time is used, charging may end before the battery
pack is fully charged. In such a case, repeat charging and discharging a number of time before use. (A
battery pack may also be in such a state immediately after purchase.)
• The life of the battery pack (when capacity is 60% or more of initial capacity) is approximately 500 chargedischarge cycles. (The life differs depending on the conditions of use.)
• To prevent battery pack deterioration when the battery will not be used for 1 month or longer, remove it and
store it in a dry location with an ambient temperature range of between −20°C to 30°C.
• When a battery pack is used, the instrument turns off automatically when the capacity drops. Leaving the
instrument in this state for a long time may lead to over discharge so be sure to turn off the power switch on
the instrument.
• The charging efciency of the battery pack deteriorates at high and low temperatures.
• The battery pack is subject to self-discharge. Be sure to charge the battery pack before initial use. If the
battery capacity remains very low after correct recharging, the useful battery life is at an end.

Operating Precautions
Attaching the Strap
Attach the strap securely at 2 locations of the instrument. If insecurely attached, the
instrument may fall and be damaged when carrying.
Using SD Memory Cards
• Do not remove a card while data is being written to it. Doing so may damage the card.
See “10.10 Removing SD Memory Card during Recording” (p. 127).
• Exercise care when using such products because static electricity could damage the SD
card or cause malfunction of the instrument.
IMPORTANT
•
Format the card with the instrument. Using a computer to format the card may reduce the
card’s performance.
See “10.9 Formatting SD Memory Card (Deleting All Files)” (p. 126).
• No compensation is available for loss of data stored on the SD memory card, regardless of the
content or cause of damage or loss. Be sure to back up any important data stored on an SD
memory card.
• Observe the following to avoid corruption or loss of stored data:
• Do not touch the electrical contacts on the card or inside the insertion slot with your skin or
metallic objects.
• While writing or reading data, avoid vibration or shock, and do not turn the power off or
remove the card from the instrument.
• Before formatting (initializing) a card, conrm that it contains no important information (les).
• Do not bend or drop the card, or otherwise subject it to intense shock.
CAUTION
CAUTION
• The operating lifetime of the SD memory card is limited by its ash memory. After long-term or frequent
usage, data reading and writing capabilities will be degraded. In that case, replace the card with a new one.
• If you are unable to write data to an SD memory card, manipulate folders and les, or format the card, check
the position of the write-protect lock and disengage it if necessary.
The connector of the SD memory card is used to judge whether the card is write-protected.
If the write-protected lock is in an intermediate position, the determination of whether the card is writeprotected will depend on the connector. For example, even if the instrument determines that the card is
not write-protected and allows data to be written to it, a computer may determine that it is write-protected,
preventing data from being written to it.
10
Using AC Adapter
• Use only the supplied Model Z1002 AC ADAPTER. AC adapter rated input voltage
range is 100 to 240 V AC at 50/60 Hz. To avoid electrical hazards and damage to
the instrument, do not apply voltage outside of this range.
• Turn the instrument off before connecting the AC adapter to the instrument and
to AC power.
• To avoid electrical accidents and to maintain the safety specications of this
instrument, connect the power cord provided only to an outlet.
Avoid using an uninterruptible power supply (UPS) or DC/AC inverter with rectangular

Operating Precautions
Wiring
• Do not short-circuit two wires to be measured by bringing the metal part of the
voltage cord clips or current sensor tips into contact with them. Doing so could
result in a severe accident such as arcing.
• To prevent electrical shock and personal injury, do not touch any input terminals
on the VT (PT), CT or the instrument when they are in operation.
• Do not use the instrument with circuits that exceed its ratings or specications.
Doing so may damage the instrument or cause it to become hot, resulting in
bodily injury.
• To avoid electric shock, be careful to avoid shorting live lines with the voltage
cords.
• We recommend measurements at the secondary side of the distribution
panel. Measurements at the primary side cause unrestricted current ow. The
instrument and equipment could be damaged if a short circuit occurs.
• To avoid short circuit or electric shock, do not touch the metal parts of the
voltage cords or current sensor tips.
DANGER
CAUTION
• To avoid damaging the instrument, do not short the voltage cord input terminals or
current sensor input terminals or input any voltage to them.
• To ensure safe operation, use only the voltage cord and current sensor specied by
Hioki.
Displayed values can frequently uctuate due to induction potential even when no voltage is applied. This,
however, is not a malfunction.
Using USB Connector (USB Cable)
CAUTION
• To avoid equipment failure, do not disconnect the USB cable while communications are
in progress.
• Use a common ground for both the instrument and the computer. Using different ground
circuits will result in a potential difference between the instrument’s ground and the
computer’s ground. If the USB cable is connected while such a potential difference
exists, it may result in equipment malfunction or failure.
• If the instrument and computer are both off and connected with the USB cable, turn on the computer and
then the instrument. Powering up the devices in a different order may prevent the instrument and computer
from communicating.
• Copying large data les from the SD memory card to a computer via the instrument’s USB interface can be
time-consuming. When you need to copy a large data le to a computer, it is recommended to use an SD
memory card reader.
12
Connecting the Instrument to an External Device
CAUTION
• Use a common ground for both the instrument and the computer. Using different ground
circuits will result in a potential difference between the instrument’s ground and the
computer’s ground. If the communications cable is connected while such a potential
difference exists, it may result in equipment malfunction or failure.
• Before connecting or disconnecting any communications cable, always turn off the
instrument and the computer. Failure to do so could result in equipment malfunction or
damage.
• After connecting the RS-232C cable, tighten the screws on the connector securely.
Failure to secure the connector could result in equipment malfunction or damage.
Using External I/O Terminals
WARNING
To avoid electric shock or damage to the equipment, always observe the following
precautions when connecting to external terminals or connectors.
• Always turn off the power to the instrument and to any devices to be connected
before making connections.
• Be careful to avoid exceeding the ratings of external terminals and connectors.
• During operation, a wire becoming dislocated and contacting another conductive
object can be serious hazard. Use screws to secure the external connectors.

Overview
1.1 Procedure for Investigating Power Quality
By measuring power quality parameters, you can assess the power quality and identify the causes
of various power supply malfunctions. The ability of the instrument to measure all power quality
parameters simultaneously makes this process a quick and simple one.
The following is the description of the investigation process for the power quality.
Step 1: Clarifying the purpose
To nd the cause for the power supply malfunction
A power supply malfunction such as an equipment failure or malfunction has occurred and
you wish to address it quickly.
Go to Step 2 (p. 16).
To assess power supply quality (power quality)
There is no known problem with the power supply, and you just want to assess the power
quality.
• Periodic power quality statistical investigation
• Testing after the installation of electric or electronic equipment
• Load investigation
• Preventive maintenance
1
Overview
Go to Step 3 (p. 16).
Step 2: Identifying the malfunctioning component (measurement
location)
Check the following:
(1) Where is the issue occurring?
• Principal electrical system
Large copier, uninterruptible power supply, elevator, air compressor, air conditioning compressor,
battery charger, cooling system, air handler, time-controlled lighting, variable-speed drive, etc.
• Electric distribution system
Conduit [electrical conduit] damage or corrosion, transformer heating or noise, oil leak, circuit
breaker operation or overheating
(2) When does the issue occur?
• Does it occur continuously, regularly, or intermittently?
• Does it occur at a specic time of the day or on a specic day of the week?
(3) What type of investigation (measurement) should be performed to nd the cause?
• Measure the voltage, current (power) continuously to analyze voltage and current trends when
the issue occurs.
• Concurrent measurements at more than one location
Examples:
• Dedicated systems lines in the electrical substation (can be measured only by the power
companies)
• High-voltage and low-voltage lines of the service entrance
• Distribution panels and switchboards
• Power feeder and outlets of power supply for electric and electronic equipment
15
Procedure for Investigating Power Quality
(4) What is the expected cause?
• Abnormal voltage
RMS value trends, waveform distortion, transient overvoltage
• Abnormal current
Leakage current, inrush current
Step 3: Checking investigation (measurement) locations (collecting
site data)
Collect information (site data) from as many locations as possible to prepare for the investigation.
Check the following:
(1) Wiring
1P2W / 1P3W /
3P3W2M / 3P3W3M / 3P4W
3P4W2.5E (available after the
rmware update)
(3) Frequency
50 Hz/60 Hz
(5) Current capacity
Current capacity is required to
select current sensors used for
the measurements.
(2) Declared input voltage
100 V to 800 V
(4) Is the voltage between the neutral line and ground,
and neutral line current required to be measured?
If the measurements are required, CH4 of the wiring settings
should be set to ON. See p. 48, and p. 64.
(6) Other items related to the whole facility
• Other systems causing power supply malfunctions
• Principal electrical system operating cycle
• Any additions or changes to facility equipment
• Check of the power distribution system in the
facilities
Step 4: Making measurements with the power quality analyzer (measurement procedure)
Measurements are performed using the following procedure:
16
Preparations
Attach accessories and optional equipment required for the measurements to the Power
Quality Analyzer.
See “2 Preparing for Measurement” (p. 35).
Measurement settings/Connections/Wiring*
Congure the conditions required for the measurements and connect voltage cord and
current sensors to the instrument.
Connect the wires to the measuring object and check if there is any mistake.
See “Installation Environment” (p. 7) and “4 Wiring (WIRING Screen)” (p. 47).
Recording settings/Event settings*
Congure the conditions and events required for recording.
If the EVENT indicator on the screen (p. 32) frequently changes to red, too many events
have occurred.
When the number of events reaches 9999 during recording/measurement, subsequent
events will not be recorded (trend recording continues). Adjust the event settings as
required.
See “5 Setting Change (SET UP Screen)” (p. 63).
Measured value check
Press the [MONITOR] key, and use the MONITOR screen to check if there is any problem
with the values measured.
See “6 Verifying the Waveform, Measured Values (MONITOR Screen)” (p. 81).
Recording start*
Press the [START/STOP] key to start recording.
See “7 Recording (Save) (SET UP Screen)” (p. 91).
Analysis/Actions
Procedure for Investigating Power Quality
1
Overview
Continue recording for the period necessary for the analysis, check the state of the power
supply malfunction based on the detected events.
Check while recording
Check after recording is
stopped
Next, take the preventive measures for the power supply malfunction.
(The instrument is effective not only for the power supply investigation but also to check
after taking the measures for the power supply malfunction.)
“8 Verifying the Trends (Fluctuations) in Measured
Values (TREND Screen)” (p. 95), and “9 Checking
Events (EVENT Screen)” (p. 105).
“11 Analysis (with Computer)” (p. 129)
*: Use “Quick Set” for easy and secure setting, and recording start!
The Quick Set allows easy and secure procedure for setting and recording start by following the
navigation of the instrument.
The event settings also allows typical setting by only selecting the menu.
(Menu: Voltage events, Inrush current, Trend record only, EN50160)
See “3 Quick Set” (p. 45), supplied Measurement Guide.
17
Procedure for Investigating Power Quality
Advice for identifying the cause of abnormalities
Record voltage and current trends at the power circuit inlet.
If the voltage drops while the building’s current consumption rises, the likely cause for power
abnormality lies inside the building. If the voltage and current are both low, the cause is likely to lie
outside the building.
It’s extremely important to select the right measurement locations and measure current for
troubleshooting.
Check power trends.
Overloaded equipment can cause problems. By understanding power trends, you can more easily
identify problematic equipment and locations.
See “8 Verifying the Trends (Fluctuations) in Measured Values (TREND Screen)” (p. 95).
Check when the problem occurs.
Equipment that is operating or turning on or off when events (abnormalities) are recorded may be
the cause of malfunction. By understanding the precise times at which events start and stop, you
can more easily identify problematic equipment and locations.
See “9 Checking Events (EVENT Screen)” (p. 105).
Check for heat and unusual sounds.
Motors, transformers, and wiring may produce heat or unusual sounds due to causes such as
overloading or harmonics.

While taking measurements on the secondary side of a voltage transformer (VT), if you set the VT
ratio, you can display the voltage value by converting it to primary-side voltage values.
Example: If the voltage on primary side of a VT is 6.6 kV and the voltage on secondary side is 110 V
then the VT ratio = 60 (6600 V / 110 V)
As the voltage range of 1000 V is xed, it would be multiplied by the VT ratio of 60 to obtain a
voltage range of 60 kV.

Selecting an appropriate current range
Set the current range based on the anticipated maximum load current that will generate during the
measurement. (Refer to the operating status, load rating, breaker rating, and other data to make this
determination.)
If the range is too low, then an over-range current will be generated during measurement, and
accurate measurement will not be possible.

While taking measurements on the secondary side of a current transformer (CT), if you set the CT
ratio, you can display the current value by converting it to primary-side current values.
Example: If the current on primary side is 200 A and the current on secondary side is 5 A then the
CT ratio = 40 (200 A / 5 A)
If the current range of 5 A is selected (with the current sensor), it would be multiplied by the CT ratio
of 40 to obtain a current range of 200 A.

Using the Instrument During an Interruption
7.2 Using the Instrument During an Interruption
If the supply of power to the instrument is cut off while recording is in progress, measurement
operation will stop during the interruption. The setting conditions will be backed up.
When the power supply is restored, the recording will reset once and it will be resumed as a new
recording.
If the Model Z1003 Battery pack has been installed, the instrument will automatically switch to
battery power in the event of an interruption and continue recording.
IMPORTANT
If the supply of power to the instrument is cut off while accessing the SD memory card, les on
the card may be corrupted. Since the SD memory card is accessed frequently when recording
with a short recording interval time, le corruption is more likely to occur if an interruption occurs
during such use.
It is recommended to avoid such inuences of interruptions by using the Model Z1003 Battery
pack supplied as an accessory.
