Shipping precautions
Handling the Instrument
To avoid electric shock, do not open the instrument's case. The internal compo-
nents of the instrument carry high voltages and may become very hot during
operation.
• If the instrument exhibits abnormal operation or display during use, review the infor-
mation in "14.2 Trouble Shooting" (p.216) and "14.3 Error Indication" (p.218) before
contacting your dealer or Hioki representative.
• To avoid damage to the instrument, protect it from physical shock when transporting
and handling. Be especially careful to avoid physical shock from dropping.
• The protection rating for the enclosure of this device (based on EN60529) is *IP30.
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.
Handling the cords and clamp sensors
• To prevent damage to the instrument and clamp sensors, never connect or discon-
nect a sensor while the clamp sensor is clamped around a conductor.
• To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it
from the power outlet.
• To avoid breaking the cables, do not bend or pull them.
• For safety reasons, when taking measurements, only use the L1000 Voltage Cord.
• Avoid stepping on or pinching cables, which could damage the cable insulation.
• Keep the cables well away from heat sources, as bare conductors could be exposed
if the insulation melts.
• When disconnecting the BNC connector, be sure to release the lock before pulling off
the connector. Forcibly pulling the connector without releasing the lock, or pulling on
the cable, can damage the connector.
• To avoid damaging the output cable, grasp the connector, not the cable, when
unplugging the cable.
• When disconnecting the clamp sensor from the instrument, be sure to grip the part of
the connector with the arrows and pull it straight out. Gripping the connector else-
where or pulling with excessive force may damage the connector.

Usage Notes
8
About the AC adapter
• Use the 9217 Connection Cord (resin) when connecting to insulated BNC connector
(resin), and the 9165 Connection Cord (metal) when connecting to metallic BNC con-
nector (metal). If you connect metal BNC cable to insulated BNC connector, the insu-
lated BNC connector can be damaged and the connection equipment may be
damaged.
• Be careful to avoid dropping the clamp sensors or otherwise subjecting them to
mechanical shock, which could damage the mating surfaces of the core and
adversely affect measurement.
• Keep the clamp jaws and core slits free from foreign objects, which could interfere
with clamping action.
• Keep the clamp closed when not in use, to avoid accumulating dust or dirt on the
mating core surfaces, which could interfere with clamp performance.
Use only the specified voltage cords and input cables. Using a non-specified cable may
result in incorrect measurements due to poor connection or other reasons.
Before Connecting Measurement Cables
• To avoid electric shock, turn off the power to all devices before plugging or
unplugging any cables or peripherals.
• Be sure to connect the voltage input and current input terminals correctly. An
incorrect connection could damage or short circuit this instrument.
• In order to prevent electric shock or device damage, observe the following pre-
cautions when making connections to the external control terminals and other
interface connectors.
• Turn off the instrument and any equipment being connected before connecting
the measurement cables.
• Exercise care not to exceed the ratings of external control terminal and inter-
face connector signals.
• Make connections securely to avoid the risk of connections coming loose dur-
ing instrument operation and bringing wires into contact with other electrically
conductive parts.
• Ensure that devices and systems to be connected to the external control termi-
nals are properly isolated.
• To avoid electric shock and short-circuit accidents, use only the supplied voltage
cords to connect the instrument input terminals to the circuit to be tested.
Always turn both devices OFF when connecting and disconnecting an interface
connector.
• To avoid electrical accidents and to maintain the safety specifications of this
instrument, connect the power cord only to a 3-contact (two-conductor +
ground) outlet.
• Turn the instrument off before connecting the AC adapter to the instrument and
to AC power.
• Use only the supplied Model Z1002 AC Adapter. AC adapter input voltage range
is 100 to 240 VAC (with ±10% stability) at 50/60 Hz. To avoid electrical hazards
and damage to the instrument, do not apply voltage outside of this range.

Usage Notes

About the battery pack
Others
For battery operation, use only the HIOKI Model Z1003 Battery Pack. We do not
take any responsibility for accidents or damage related to the use of any other
batteries.
• 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.
• To avoid problems with battery operation, remove the batteries from the instrument if
it is to be stored several week or more.
Avoid using an uninterruptible power supply (UPS) or DC/AC inverter with rectangular
wave or pseudo-sine-wave output to power the instrument. Doing so may damage the
instrument.
Before Connecting to the Lines to be Measured
• To avoid short circuits and potentially life-threatening hazards, never attach the
clamp sensor to a circuit that operates at more than the maximum rated volt-
age to earth
(See your clamp sensor's instruction manual for its maximum ratings.)
• The maximum input voltage is 1000 VAC, ±600 VDC. Attempting to measure
voltage in excess of the maximum input could destroy the instrument and
result in personal injury or death.
• To avoid electrical hazards and damage to the instrument, do not apply voltage
exceeding the rated maximum to the input terminals.
• The maximum rated voltage between input terminals and ground is 600 VDC/
AC. Attempting to measure voltages exceeding 600 V with respect to ground
could damage the instrument and result in personal injury.
• Connect the clamp sensors or voltage cords to the instrument first, and then to
the active lines to be measured. Observe the following to avoid electric shock
and short circuits.
• Do not allow the voltage cord clips to touch two wires at the same time.
• Never touch the edge of the metal clips.
• When the clamp sensor is opened, do not allow the metal part of the clamp to
touch any exposed metal, or to short between two lines, and do not use over
bare conductors.
• When connecting a clip-type input cord, you will need to clip the line to the ter-
minal while it is hot. Bringing two wires into contact with each other while con-
necting the clips will cause a short-circuit.
• To prevent electrical shock and personnel injury, do not touch any input termi-
nals on the VT (PT), CT or the instrument when they are in operation.

Usage Notes
10
• To avoid electrical accidents, confirm that all connections are secure. The
increased resistance of loose connections can lead to overheating and fire.
• Ensure that the input does not exceed the maximum input voltage or current to
avoid instrument damage, short-circuiting and electric shock resulting from
heat building.
• To avoid electric shock when measuring live lines, wear appropriate protective
gear, such as insulated rubber gloves, boots and a safety helmet.
When the instrument's power is turned off, do not apply voltage to the instrument.
Doing so may damage the instrument.
While Measuring
If an abnormality such as smoke, strange sound or offensive smell occurs, stop
measuring immediately, disconnect from the measurement lines, turn off the
instrument, unplug the power cord from the outlet, and undo any changes to the
wiring. Contact your dealer or Hioki representative as soon as possible. Continu-
ing to use the instrument may result in fire or electric shock.

Chapter 1 Overview
The PW3198 Power Quality Analyzer is an analytical instrument for monitoring and recording
power supply anomalies, allowing their causes to be quickly investigated. The instrument can
also be used to assess power supply problems (voltage drops, flicker, harmonics, etc.).
Overview Chapter 1
1.1 Product Overview
Record abnormal waveforms
Record voltage fluctuations
Observe power supply waveforms
Measure harmonics
Measure flicker
Measure power
One instrument does it all!
How does the PW3198 record abnormal waveforms?
The instrument automatically judges and records a range of problems:
Transient voltages
Transient voltages are caused by lightning strikes, circuit-breaker and relay
contact obstructions and tripping, and other phenomena. They are often char-
acterized by precipitous voltage variations and a high peak voltage.
Flicker (V10, IEC)
Flicker is caused by blast furnace, arc welding, and thyristor control loads. The
resulting voltage fluctuations cause flicker in light bulbs and similar phenom-
ena.
Voltage dips (falling voltage)
Short-lived voltage drops are caused by the occurrence of a inrush current with
a large load, such as when a motor starts.
Interruptions
In an interruption, the supply of power stops momentarily or for a short or long
period of time due to factors such as a circuit breaker tripping as a result of a
power company accident or power supply short-circuit.
Voltage swells (rising voltage)
In a voltage swell, the voltage rises momentarily due to a lightning strike or the
switching of a high-load power line.
Harmonic and high-order harmonic elements
Harmonics are caused by distortions in the voltage and current caused by the
semiconductor control devices that are frequently used in equipment power
supplies.
