This guide explores three important HIOKI platforms and explains how to choose a suitable solution for your application.

What Are HIOKI Data Acquisition Systems?

A data acquisition system, commonly known as a DAQ system, collects signals from sensors, converts them into digital data, and stores the results for analysis.

Depending on the instrument and installed modules, measurements may include voltage, current, temperature, resistance, humidity, strain, and vehicle communication signals such as CAN or CAN FD.

HIOKI offers different instrument categories to address different measurement requirements.

Data Loggers

Data loggers are designed to monitor multiple measurement points over extended periods. They are particularly useful for temperature monitoring, battery evaluation, environmental testing, and industrial process analysis.

Digital Oscilloscopes

Digital oscilloscopes display and analyze rapidly changing electrical waveforms. They are commonly used for circuit debugging, switching analysis, and signal integrity testing.

Memory Recorders and ScopeCorders

Memory recorders combine high-speed waveform capture with flexible multichannel recording. They are useful when engineers need to investigate transient events while observing several electrical or physical signals.

The best choice depends on the required bandwidth, sampling rate, recording duration, channel count, and measurement conditions.

HIOKI LR8450 Memory HiLogger: Flexible Multichannel Recording

The HIOKI LR8450 is a portable, modular data logger designed for applications requiring multiple measurement channels and flexible sensor integration.

It supports up to 120 wired channels, depending on the installed plug-in modules. The LR8450-01 wireless model can support additional wireless measurements when configured with compatible modules.

Key Features of the LR8450

Modular measurement capability: Compatible modules support different measurement types, including voltage, temperature, resistance, strain, current, and CAN/CAN FD data.

Wireless measurement options: The LR8450-01 can work with compatible wireless modules, helping reduce sensor wiring in vehicle tests and other installations where cables are difficult to route.

Portable operation: Its design supports laboratory and field measurement work, making it useful for engineers who need to collect data at different test locations.

Typical Applications

The LR8450 is suitable for electric vehicle battery testing, thermal mapping, HVAC evaluation, motor testing, strain measurement, and long-duration industrial monitoring.

For example, an engineer evaluating a battery pack may need to monitor temperature at multiple locations while collecting electrical or vehicle communication data. A suitably configured LR8450 can help bring these measurements together for analysis.

HIOKI MR6000 Memory HiCorder: High-Speed Waveform Analysis

The HIOKI MR6000 is a modular memory recorder designed for demanding tests involving transient signals, high-speed waveforms, and multiple synchronized measurements.

With the compatible U8976 High-Speed Analog Unit, the system supports simultaneous sampling at up to 200 MS/s on two input channels of that module. This capability is valuable when analyzing rapid switching events and other high-frequency electrical phenomena.

Main Advantages of the MR6000

High-speed sampling: The compatible U8976 module provides a maximum sampling rate of 200 MS/s and a frequency bandwidth of 30 MHz, supporting detailed waveform analysis within its specified limits.

Modular inputs: Engineers can configure the recorder with compatible input units for different electrical and physical measurement requirements.

Large recording capacity: The MR6000 supports up to 1 G-word of internal memory, depending on the applicable configuration and recording setup.

Advanced recording functions: Triggering and waveform analysis functions help engineers capture important events and investigate abnormal operating conditions.

Automotive communication measurements: With compatible modules and configuration, the system can support CAN, CAN FD, and LIN-related testing.

Typical Applications

The MR6000 is particularly relevant to inverter development, motor-drive analysis, switching power supply evaluation, automotive electronics, and power semiconductor testing.

For example, an engineer investigating an inverter may need to capture fast voltage transitions and compare waveforms across measurement channels. The MR6000 provides a suitable platform when its configured sampling rate, bandwidth, input range, and isolation meet the test requirements.

HIOKI MR8827 Memory HiCorder: High-Speed Multichannel Recording

The HIOKI MR8827 is another modular memory recorder designed for synchronized multichannel waveform acquisition.

It supports sampling rates up to 20 MS/s and configurations of up to 32 analog channels plus 32 logic channels, or 28 analog channels plus 64 logic channels when the required logic units are installed.

Its isolated input architecture makes it useful for measuring different signals in applications such as inverter evaluation, railway testing, industrial troubleshooting, and motor-drive analysis.

The MR8827 also supports a combination of analog and logic measurements, allowing engineers to investigate the relationship between electrical behavior and digital control signals.

One important purchasing consideration is that the main unit requires compatible input modules. Buyers should verify the complete configuration before ordering.

HIOKI Data Acquisition Systems: Technical Comparison

The following table summarizes the principal differences between the three instruments. Specifications depend on the installed modules and selected configuration.

Important: A 1 ms recording interval is not equivalent to a 1 MS/s sampling rate. Always compare the actual sampling specifications for the selected measurement module rather than treating these values as interchangeable.

Five Essential Factors When Selecting a HIOKI Instrument

Choosing among HIOKI data acquisition systems becomes easier when you define your measurement requirements before purchasing.

1. Determine the Required Sampling Rate

Start by identifying how quickly the signal changes. Temperature monitoring may require relatively slow recording, while switching transients can demand much faster sampling and sufficient analog bandwidth.

Select an instrument that can capture the signal characteristics relevant to your analysis.

2. Calculate the Required Channel Count

Count every signal that must be recorded simultaneously, including voltage, current, temperature, strain, and digital control signals.

Allow additional capacity if you expect your testing requirements to expand.

3. Verify Electrical Isolation and Safety

Isolation requirements depend on the measured voltage, circuit topology, installation environment, and applicable safety standards.

Check the ratings of the specific input module, probes, leads, and accessories. Never assume that every module supports the same voltage or safety category.

4. Confirm Sensor and Module Compatibility

Not every HIOKI main unit supports every input module. Before ordering, confirm the required sensor types, input ranges, connectors, sampling performance, and module compatibility.

Also check whether probes, cables, software licenses, and other accessories are included or must be purchased separately.

5. Evaluate Storage and Data Analysis

High-speed recording can generate large volumes of data. Consider recording duration, memory capacity, available storage options, export formats, and compatibility with your analysis workflow.

These factors can influence both the practical usability and total cost of the measurement system.

Applications of HIOKI Measurement Equipment

HIOKI instruments support a variety of industrial and engineering applications.

• Electric vehicles and batteries: Monitor temperature, voltage, current, and compatible communication signals.
• Power electronics: Capture switching waveforms and investigate inverter behavior.
• Motor and drive testing: Analyze electrical signals alongside compatible speed, strain, or vibration measurements.
• Industrial monitoring: Record equipment behavior and investigate intermittent faults.
• Transportation and railway systems: Evaluate electrical signals and related operating parameters during testing.
• Research and development: Collect synchronized measurements for product validation and engineering analysis.

The appropriate instrument depends on the required measurement range, sampling performance, input configuration, and test environment.
