The circuit from the service drop to the service
entrance, and to the power meter and primary
overcurrent protection device (distribution panel).
Measurement categories (Overvoltage categories)
9600, 9601 and 9602 instrument comply with CAT III (600 V or less)/ CAT
II (600 to 1000 V) safety requirements.
9603 instrument complies with CAT I safety requirements.
To ensure safe operation of measurement instruments, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT I to
CAT IV, and called measurement categories. These are defined as follows.
Higher-numbered categories correspond to electrical environments with
greater momentary energy. So a measurement device designed for CAT III
environments can endure greater momentary energy than a device designed
for CAT II.
Using a measurement instrument in an environment designated with a
higher-numbered category than that for which the instrument is rated could
result in a severe accident, and must be carefully avoided.
Never use a CAT I measuring nstrument in CAT II, III, or IV environments.
The measurement categories comply with the Overvoltage Categories of the
IEC60664 Standards.

Notes on Use
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 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 ( ), 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 (• •) or phase angle (• •) 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.

viii
Notes on Use
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
representative.

Overview
1.1 Product Overview
The 3193 POWER HiTESTER is a power meter that can test any type of
line ranging from single-phase lines to three-phase four-wire lines.
Based on the voltage, current, and active power measurements, this unit
calculates and displays reactive power, apparent power, power factor, phase
angle, and efficiency. It further has a wide range of measurement functions
including frequency measurement function, peak measurement function,
current integration, active power integration, analog outputs, monitor outputs,
and harmonic analysis/flicker function (option).

1.2 Features
1.2 Features
The 3193 POWER HiTESTER features a safe design that complies with the
IEC61010-1 safety standard.
This single power meter is capable of measuring power on all types of power
lines, ranging from single-phase lines to three-phase four-wire lines by
installing the input units.
Up to six input channels can be installed, so that for example, a single unit
can simultaneously measure the input power and output power of a three-
phase inverter.
By combinations with the optional external input units, the input power and
output power of an inverter and the output of a motor can be measured and
calculated with a single unit. Further, by using the efficiency calculation
function, the efficiency and overall efficiency of up to three points can be
measured simultaneously with one unit.
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 clamp input unit, existing clamp sensors can be used
to measure up to 500 A.
The basic accuracy of• •0.1% rdg.• •0.1%f.s. is high.
The wide frequency response supports the evaluation of inverter-motor
systems, inverter fluorescent lighting systems, ultrasound motors, switching
power supplies, and so on.
The cut-off frequency can be selected from three values. This function allows
an inverter fundamental frequency to be extracted, and also supports data
exchange with conventional devices.
Three types of calculation for apparent power and reactive power can be
selected, to support compatibility with conventional devices.

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.
For current and active power, positive, negative, and total integrated values
are provided.
Each channel can be integrated separately.
Time average, sliding average, or exponential average can be selected as the
averaging mode.
The unit has a three-channel frequency measurement function, allowing
separate frequency measurement when multiple systems are being tested.
Since the frequency ranges can be combined with low-pass and high-pass
filters, it is possible for example to measure the fundamental frequency of an
inverter or a carrier frequency.
It is possible to input a separate analog output (or pulse signal) from the
system undergoing power measurement, for easy on-screen conversion.
For example, inputting the analog outputs from a torque meter or rotation
counter enables the converted torque or rotation values to be shown on the
screen. The power can also be computed from the torque or rotation values.
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 IEC-
61000-3-3.
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.

1.2 Features
The built-in floppy disk drive facilitates data saving when required, and
automatic saving at preset times.
It is also possible to save the unit settings and reload them to restore the
previous state. Upgrades of the unit are also supported.
These output specified items, with an output of • •5 V corresponding to the
full scale range.
This provides three efficiency calculations from measured power values.
These outputs provide 5 V full-scale analogs of the voltage, current, and
active power ranges. (Excluding 1000 V range)
When the response is set to FAST, these have a 100 ms response time.
These outputs provide 1 V full-scale waveform outputs corresponding to the
voltage and current ranges, allowing waveform monitoring with a recorder or
oscilloscope.
This provides a printout of the measurement data and screen displays.
The display language can be selected as English or Japanese.
