What the HIOKI 8730-10 /8731-10 WAVE COMPARATOR
can offer you:
Low price and easy operation
Physically designed for integration in production lines
Compared to the HIOKI MEMORY HiCORDER 8835 -01, waveform
evaluation can be implemented at less than half the cost. Operation
flow is suitable for a production line environment. The memory
capability of the multi-function MEMORY HiCORDER has
been streamlined for a single purpose. The setup screen employs
Windows-like pull-down menus for easy operation.
All operation switches and the display screen are arranged on the
front panel, while the measurement input and control input/output
connectors are located on the rear. The metal plate enclosure is flat
on all sides to facilitate installation in a rack or a control panel.
Handles and feet are removable and can be mounted on the top if
desired.
Resistant to tough working environments
Versatile external control
The sheet key switches have a flat surface and are accommodating to
environments where grease or other contaminants exist. There are no
openings between the controls and the unit chassis, so that the keys
cannot be gummed up by dust, etc. The PC Card slot on the front
panel is equipped with a lid that provides basic dust proofing, which
automatically closes when a PC Card is inserted.
The external control connectors are isolated and allow connection
also of a sequencer or other device with separate ground potential.
If 24V DC is externally supplied, the control signals can operate at
24V. Using the internal isolated 5V power supply for control is also
possible. Separate evaluation result output signals are provided for
area and numeric evaluation. The two-channel model has a dedicated
output for each channel.
Conveniently store data on PC Cards
High-speed operation with 1M-sample/second
Data compatibility with the HIOKI MEMORY HiCORDER 8835 -01
also makes it easy to display and print waveform data on the
8835 -01, as well as conduct further data analysis. An evaluation
area created on the MEMORY HiCORDER 8835 -01 can be used or
edited on the WAVE COMPARATOR 8730 -10 /8731-10.
The high sampling speed of the 8730 -10 / 8731-10 is ideal for
not only conventional mechanical systems but also electrical
applications. The sampling frequency is 1/100 of the time axis range,
resulting in 1-μs sampling at 100 μs/DIV.

Suitable for a wide range of uses. Realize your own ideas.
- Application examples Motor operation testing
Hydraulic pressure testing
Waveform evaluation can be used to test
whether a motor is operating normally. To
do this, the actual waveform is compared to
the control signal tolerance range. Because
t he 8 73 0 -10 / 8 731 -10 a l lows st or i ng of
measurement data on a PC Card, test data
management can be implemented easily.
X-Y waveforms such as pressure/flow of a pump or pressure/stroke
of a hydraulic press can be tested with the two-channel model
8731-10 . The two inputs are suitable for X-Y waveform
measurement, and Lissajous and other donut-shaped
patterns can also be evaluated.
Welding quality check
Gear pre-load testing
Machining precision is an important factor for
assuring that driving force transmission gears
mesh smoothly. Torque fluctuations
that arise during gear rotation can be measured
and evaluated with the WAVE COMPARATOR. Automatic storing
of waveform data for each sample makes data handling simple and
quick.
Simply monitoring the current value often
is not enough to evaluate the quality of a
welding step. Especially in automated lines
where welding robots are used, evaluation
of current waveform patterns is highly useful for checking and
maintaining quality.

Basic steps for area evaluation
- Operation examples Simple operation
Simultaneously perform area and numeric evaluation. The screen shown below is an example for a
PASS result, using a green background. The overall evaluation result is shown at the top left, with
details shown below this and numeric results displayed at the bottom of the screen.
This is a FAIL result screen.
The background is red, making the status
easy to discern also from a distance.
Operation is very simple, using the cursor
keys while watching the screen. To accept
a setting, press SET. To switch between
different screens, use the MENU keys at
the top.
The "Configure" menu at the top of the screen
opens a list for controlling the time axis and
making other settings. In the above example,
1DIV = 100µs is selected.
Load the measured waveform into the "Editor"
window. (You can also create a new area from
scratch without loading a waveform.)
The "Unit" menu at the top of the screen opens a
list for controlling the voltage range and making
other settings. In the above example, 1DIV = 1V is
selected.
Based on the loaded waveform, create an
evaluation area by expanding the graph in the
vertical and horizontal plane. The amount of
shift is specified in DIV increments.
Measure a "Good" waveform and use it to
create an evaluation area.
By placing a box frame around a section, you
can enlarge or reduce a specific segment of the
area.

Model 8731-10 has two inputs for simultaneous evaluation
of two waveforms
- Operation examples Two channels for further enhanced performance
The inputs of Model 8731-10 (2-channel model) are shown below. The M3.5mm screw terminals are convenient when designing the
wiring layout of a production line. For different requirements, specifications can also be changed to BNC connectors. (Please contact your
local HIOKI distributor for details.) For safety, all inputs are isolated from chassis ground and from each other.
Rear view (input terminals)
Front view (2-channel evaluation example)
Evaluation screen can be divided into two windows without impairing resolution
When performing 2-channel evaluation with the 8731-10 (2-channel model), you can tile the screen horizontally into two sections. On
screen, this means that display resolution is halved, but evaluation precision is not affected. The internal processing memory continues
to perform highly accurate evaluation using the full screen resolution.
When tiling the screen
horizontally, display
resolution is reduced
by a factor of 2, but...
Full screen display example
Tiled screen display example: Evaluation is still performed at
full screen resolution, so there is no drop in accuracy.
Time axis evaluation of X-Y Lissajous waveform and donut-shaped patterns
Because area evaluation is based on screen
display pixels, complex donut-shaped patterns
such as shown at right can also be evaluated.
Evaluation devices from other manufacturers
use A/D conversion and base their area
assessment on digital values. Therefore, they
can only judge whether nor not the upper and
lower limits have been exceeded. Models
8730 -10 and 8731-10 on the other hand can
also perform FAIL evaluation in the center of
the range, something that is not possible with
competing products. (X-Y measurement is possible
only with Model 8731-10)
Evaluating a time axis waveform using a donutshaped area : FAIL evaluation of a pulse with
insufficient amplitude
Using 2-channel input for X-Y Lissajous waveform
evaluation: Vertical and horizontal voltage input allows
Lissajous waveform evaluation.
(Only with Model 8731-10 )

Numeric processing and evaluation, data store capability,
communication ready
- Operation examples Numeric processing and evaluation functions
Choice of four different types of numeric evaluation functions available. Upper and lower limits can be set against which the results of
numeric processing are to be compared. Besides maximum and minimum values, many other processing items (total 20 items) are also
provided. Dual evaluation capability means that area evaluation and numeric evaluation can be performed at the same time. The evaluation
result screen shows the overall PASS/FAIL result at the top left, and details on area evaluation and numeric evaluation 1 - 4 below this.
Store evaluation area data and setup parameters for repeat applications
The internal memory of the unit holds information on up to 16
different evaluation areas. Separate area evaluation settings can
be stored for each channel. Memory slots are numbered A01 A16 and can be selected freely. A reduced size graph of the area
shape is shown besides each selection, making it easy to pick the
one you want.
In addition, 16 different setup parameters can be stored in the
internal memory and selected also via external control or key
operation.
Convenient data save and transfer functions
Measurement data ca n be stored on PC Ca rds which is
convenient for archiving test data for production lines.
A LAN connector (10BASE-T) and RS-232C interface are provided
as standard features. This lets you link the units to a PC network
for easy access to important data.
(LAN COMMUNICATOR 9333 is required to save data on a PC network, sold
separately.)

Output timing of evaluation result
- How it works -
External control connectors insulated from chassis
External DC power can be 12V or 24V, and control signal
input also operates at this voltage. Using the internal isolated
5V power supply for control is also possible. Because the
terminals are isolated from chassis ground, connection of a
sequencer, relay bank, or other device with separate ground
potential presents no problem.
External control connectors provided as standard equipment (rear panel)
Evaluation result output timing
The diagram below shows the evaluation output cycle when performing area evaluation only for a 1kHz sine wave signal. When
auto store is selected, data store processing occurs after the evaluation processing step. The evaluation time and evaluation cycle for
numerical processing depend on the processing type and recording duration, and also on the evaluation waveform.
