• 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 charge-

discharge 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 efciency 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. 133).

• 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. 132).

• 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, conrm that it contains no important information (les).

• Do not bend or drop the card, or otherwise subject it to intense shock.

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 Hz/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 specications of this

• 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 specications.

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 specied 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

• When any device that does not accept the power supplied through Pin 9 is connected

to the RC-232C interface of the instrument, do not set the RS-232C connection destination to Bluetooth. Doing so will damage the connected device.

• 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.

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. 15).

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 specic time of the day or on a specic 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 voltage

• 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 (DC) / 1P3W / 3P3W2M / 3P3W3M / 3P4W / 3P4W2.5E

(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

50 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:

Preparations

16

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*

Congure 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*

Congure 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).

Procedure for Investigating Power Quality

1

Recording start*

Press the [START/STOP] key to start recording. See “7 Recording (Save) (SET UP Screen)” (p. 93).

Analysis/Actions

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.)

*: 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.

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. 97).

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. 111).

Check for heat and unusual sounds.



Motors, transformers, and wiring may produce heat or unusual sounds due to causes such as overloading or harmonics.

If a current peak over, i.e., that the peak of the current exceeds 400% of the present

range or falls below −400% of it, occurs, the background of the current range turns red.

If a current overrange, i.e., that the current exceeds 130% of the present range, occurs, the background of the current range turns yellow.

When a voltage value exceeds a certain ratio based on the declared input voltage, the background color turns any of the following colors: 110% < Yellow

90% ≤ (Regular background color) ≤ 110% 80% ≤ Yellow < 90%

Red < 80%

When the measured value is different from the declared frequency, the background of the declared frequency turns red. The background turns red even when measuring a DC voltage.

Measured value became overrange (the measurement is out of measuring range). The voltage that the instrument is capable of measuring is being exceeded. Immediately disconnect the instrument. If the current is overrange, increase the current range.

Measurement is not possible. Shown instead of the measured value. If there is no input, the power factor cannot be measured.

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. And if the range is too high, then errors will increase and accurate measurement will not be possible.

When measuring power lines that use multiple channels

Combine the multiple types of the current sensor. Example: Use current sensors of the same type from CH1 to CH3 for the 3-phase 4-wire system.

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. And if the range is too high, then errors will increase and accurate measurement will not be possible.

The present current value will be displayed.

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.
