────────────────────────────────────────────────────
Notes on Use
In order to ensure safe operation and to obtain maximum performance from
the unit, observe the cautions listed below.
DANGE R
WARNING
Always connect the powermeter input (including clamp) to the
secondary side of the breaker. On the secondary side of a breaker,
even if the lines are shorted the breaker can trip and prevent an
accident. On the primary side, however, the current capacity may be
large, and in the event of a short-circuit there may be a serious
accident.
The maximum input voltage and current for this unit depend on the
input unit being used. Do not apply an input exceeding the maximum
input voltage and current specified for the input unit. Exceeding the
maximum input voltage or current could damage the unit or cause a
serious accident.
Before turning on the power, make sure that the voltage of the power
supply being used matches the supply voltage indicated on the rear
panel of the unit. If an attempt is made to use an improper supply
voltage, there is danger of damage to this unit and of life-threatening
risk to the operator.
The power switch has a microgap construction, and it is therefore
essential to use it close to a power outlet. When the unit is not in
use, and while making connections to the circuit being tested, isolate
the unit electrically from the power supply, for example by removing
the power cord plug from the outlet.
The unit is constructed so as to be connected to a ground line via a
three-core power cord that is supplied with the unit. In order to avoid
electric shock, connect the unit to a properly grounded (3-pin) outlet
using the power cord provided.
Do not remove the case of the unit. There are components inside
carrying high voltages or becoming hot, and this could cause an
electric shock accident.
Do not use the unit where it may be exposed to corrosive or
explosive gases. The unit may be damaged, or explosion may occur.
────────────────────────────────────────────────────
Notes on Use
viii
────────────────────────────────────────────────────
CAUTION
・ Should the unit emit smoke, or a strange smell or strange sound,
immediately stop testing operations, power the unit off, and remove
the power cord from the outlet, shut off the circuit being tested,
disconnect the unit, and consult your HIOKI representative.
Continued use of the unit could lead to fire or electric shock
accidents.
・ Do not insert foreign objects through the ventilation holes in the top
and bottom of the case. Particularly if metallic, liquid, or combustible
substances get inside the case, this may lead to fire or electric
shock, or to malfunction.
・ Never allow the ventilation holes in the top and bottom covers to
become blocked while using this unit. Blocking the ventilation will
cause internal temperature to rise, possibly resulting in fire or
damage to the equipment.
・ To prevent electric shock, do not allow the unit to become wet and
do not use the unit when your hands are wet.
・ This unit is designed for indoor use and can be safely used at
temperatures ranging from 0℃ to 40℃ and should be operated at
80% RH or less.
・ This unit is not constructed to be waterproof or dustproof, so do
not use it in a very dusty environment or in one where it will get
wet.
・ Do not store or use the unit where it will be exposed to direct
sunlight, high temperatures, high humidity, or condensation. If
exposed to such conditions, the unit may be damaged, the insulation
may deteriorate, and the unit may no longer satisfy its
specifications.
・ To avoid damage to the unit, do not subject the equipment to
vibrations or shocks during transport or handling. Be especially
careful to avoid dropping the equipment.
・ Do not place the unit on an unstable stand, or in an uneven
location. It may fall to the ground, or fall over, and either of these
events may lead to malfunction or accident.
・ Do not use the unit near any device which generates strong
electromagnetic radiation or near a static electrical charge, as these
may cause errors.
・ Avoid treading on or pinching the cable so as not to damage the
cable sheaths.
・ When unplugging the power cord from the power receptacle or from
the unit, grasp the plug, not the cord, in order to avoid damaging the
cable.
・ To avoid damaging the sensor cables or probes, do not bend or pull
them, especially where they connect to the sensor.
・ Use caution when taking measurements in circuits where the power
line are hot.
・ Keep the cables well away from heat, to prevent the possibility of
melting the insulation.
・ For long-term storage, remove the power cord.

────────────────────────────────────────────────────
NOTE
･ All options for this unit are factory-fitted, but it is also possible to add
options at a later date after purchase. In this case, however, it is necessary
for the unit to be returned to HIOKI headquarters.
･ With the appropriate combination of direct connection input units, this unit
can function as either an AC power meter or dual AC/DC power meter.
When used together with clamp input units, depending on whether the clamp
sensor used is for AC or DC, this unit can function as either an AC power
meter or dual AC/DC power meter. When used as an AC power meter, it is
not possible to measure a DC component superimposed on the AC signal
(half-wave rectification, or full-wave rectification upper and lower excluded
waveform).
･ Note that limits are specified for the range in which voltage and current level
accuracies are guaranteed.
･ In order to assure accurate measurements, allow this unit to warm up for at
least 1 hour before using it.
･ This power meter uses the calculations indicated in the specifications in
order to determine apparent power (S), power factor (
λ
), and reactive power
(Q) on the basis of the measured voltage (U), current (I), and active power
(P). The values displayed by this power meter may differ from those
produced by other testers that are based on different principles of operation
or testers that use different calculations.
･ Display of a polarity symbol (-) together with reactive power (Q), power
factor (λ) or phase angle (φ) occurs only when TYPE1 is selected as the
calculation type, and indicates that current is delayed with respect to
voltage. For reasons related to circuit design, the polarity symbol is
displayed even when input is "0".
･ Due to measuring error or a disproportionate load, the effective power may
exceed the apparent power, resulting in a power factor of 1 or more. In such
a case, this system is designed to make the apparent power equal to the
effective power.
･ There are two sorts of measurement: using analog calculation by the input
unit or by digital calculation using the harmonic analysis/flicker
measurement function, and since these have entirely different principles of
measurement, frequency range, and accuracy, and as a result the final
measured values may be different.
･ Accurate measurement may be impossible in locations subject to strong
external magnetic fields, such as transformers and high-current conductors,
or in locations subject to strong external electric fields, such as radio
transmission equipment.
･ For the current measurement of the 9600 AC/DC DIRECT INPUT UNIT, the
DC-CT (current transformer) method is used, so after measuring a large
current, there may be a very slight residual offset signal. The offset signal
produces the largest error effect in the minimum ranges; in this case, shut
off the current input, and carry out degaussing (DMAG).
･ The 9600, 9601, and 9602 active power measurement units operate with an
auto-zero circuit at 2.442 kHz. For this reason, an input signal with a
frequency of 2.442 kHz will result in a periodically fluctuating display
indication.
────────────────────────────────────────────────────
Notes on Use
x
────────────────────────────────────────────────────
NOTE
･ When the input is less than a certain level of measurement range, depending
on using the input unit, the display value is forced to zero. See the
specifications of the input unit to be used.
･ When measuring a high frequency voltage to earth (for example the
secondary side of an inverter), errors may occur in the measurement values.
･ To maintain the measurement accuracy of the unit, bear the following
cooling measures in mind:
Do not obstruct the ventilation holes
Keep away from sources of heat
If rack mounted, install a cooling fan
･ This unit switches the power supply voltage automatically. Voltage
fluctuations of 10% from the rated supply voltage are taken into account.
･ This unit has no external fuse. Thus if the unit does not operate when the
power switch is turned on and power is supplied, there is a fault. Disconnect
the power cord and measurement lines, and contact your dealer or HIOKI
representative.
･ This instruments 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.

────────────────────────────────────────────────────
1.2 Features
(1) Simultaneous measurement of multiple systems
Up to six input units can be installed on the meter and you can measure the
input and output of a 3-phase inverter with only one meter.
(2) Harmonic analysis up to 3000th harmonic
The power meter is capable of conducting an analysis including carrier
frequencies, not only the fundamental frequencies like those on the
secondary side of an inverter. This enables an analysis of a loss by a carrier
component.
The number of data that can be obtained is up to 50. Please see the
operations manual of the 9605-01 HARMONIC MEASUREMENTS UNIT.
(3) Phase measurement using external synchronizing signals
The power meter is capable of measuring phases using a signal from an
external device as the reference. When measuring a synchronous motor, for
example, the meter uses the pulses of the rotating shaft and measures the
difference in angle between the rotor and the stator due to the torque as an
electrical angle.
Please see the operations manual of the 9605-01 HARMONIC
MEASUREMENTS UNIT.
(4) Wide current measurement range
With a direct connection input unit, and no external current transformer, it is
possible to measure a maximum of 50 A rms. The internal current
transformer design keeps the losses in the current measurement meter
extremely low. Using a current sensor input unit, existing clamp sensors can
be used to measure up to 500 A.
(5) High accuracy
The basic accuracy of±0.1% rdg.±0.1%f.s. is high.
(6) Wide frequency range: DC and 0.5 Hz to 1 MHz (using optional
9600
AC/DC DIRECT INPUT UNIT
)
The wide frequency response supports the evaluation of inverter-motor
systems, inverter fluorescent lighting systems, ultrasound motors, switching
power supplies, and so on.

(9) Peak measurement function
It is possible to measure peak values of a voltage or current waveform.
Also, using the peak hold function, motor surge current peak values, and the
peak values of effective values can be measured.
(10) Separate integration values for each polarity
For current and active power, positive, negative, and total integrated values
are provided.
Each channel can be integrated separately.
(11) Three averaging functions
Time average, sliding average, or exponential average can be selected as the
averaging mode.
(12) Three-channel frequency measurement function
The unit has a three-channel frequency measurement function, allowing
separate frequency measurement when multiple systems are being tested.
(13) Direct input from torque sensor (Option: 9603-01 EXTERNAL SIGNAL
INPUT UNIT)
If it is a strain-gauge torque sensor, the sensor can be connected to the
power meter directly without an exterior amplifier.
The power meter is immune to the influence of cable length or bridge
resistance, thanks to its sense function.
The power meter also supports analog output signals (DC) from an exterior
amplifier.
Please see the operations manual of the 9603-01 EXTERNAL SIGNAL
INPUT UNIT.

(14) Harmonic analysis/flicker measurement function (option)
The harmonic analysis function can analyze up to the 50th harmonic of the
voltage, current, or active power waveform, for fundamental frequencies
from 5 Hz to 440 Hz.
There is also support for measurement according to IEC 61000-3-2 or the
Japanese Ministry of International Trade and Industry's guidelines for
harmonic suppression in household and general-purpose products. The flicker
measurement function follows the measurement method laid down by IEC61000-3-3.
(15) High visibility color LCD
The color LCD screen has a wide viewing angle, and allows simultaneous
display of different information without requiring screen switching, giving an
at-a-glance grasp of the overall state of the measured system. In combination
with the optional harmonic analysis/flicker function, it is possible to use
different colors to distinguish harmonic analysis graphs and waveforms.
