Specifically engineered in shape and functionality for seamless integration into production lines, the units are reasonably priced and easy to operate. Compared to the more expensive multi-functional devices, the 8730-10/8731-10 can accomplish a specific number of tasks with optimum efficiency. Define a range and perform area evaluation, conduct numeric evaluation using upper and lower thresholds, or perform both of these functions all at the same time. 2 Use the WAVE COMPARATOR for evaluation or store data for subsequent PC analysis - 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 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. 3 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. ■ External view and dimensions Color LCD Sheet key switches are impervious to dirt 144 mm (Protective cover can be easily replaced if scratched) Measurement input terminals with M3.5 screws (Isolated from each other and from chassis) Screw type terminals are provided for easy wiring in production lines.

When mounting the unit on top of a control installation, screw fastening is possible by removing the plastic extensions and fitting the supplied left/right brackets. Large handle for convenient por tability and transport. By angling the feet, the instrument can be positioned as desired for easy viewing. 4 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. 5 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 ) 6 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.)

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.
