- Features -

How the WAVE COMPARATOR has answered customer

demands:

● The power of the MEMORY HiCORDER is ideal for

waveform evaluation, but integration into a control

rack is difficult...

● We are looking to replace our old oscilloscopes used

for visual monitoring, but we have a budget to meet...

● We've been using waveform evaluation instruments

made by a control equipment manufacturer, but we

can't store our data...

● Our existing evaluation devices can't sample at

higher rates...

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

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

the 8730-10 /8731-10 allows storing 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.

Gear pre-load testing

Welding quality check

Machining precision is an important factor for

assuring that driving force transmission gears

mesh smoothly. Torque fluctuations

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.

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.

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

The "Unit" menu at the top of the screen opens a

create an evaluation area.

other settings. In the above example, 1DIV = 1V is

selected.

Load the measured waveform into the "Editor"

window. (You can also create a new area from

scratch without loading a waveform.)

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.

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

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 can be stored on PC Cards 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.
