Hioki MR6000 Memory HiCorder - Change the Way You Measure, Record and Analyze

The MR6000’s 12.1-inch capacitive touch panel facilitates smooth, intuitive operation by allowing you to select settings simply by tapping them and to zoom in on waveforms with standard finger gestures. Moreover, the Waveform Search function makes it easy to search large volumes of measurement data for the waveforms you wish to view. The instrument can also automatically search all measured data for anomalous waveforms.

High-speed isolated measurement at 200 MS/s

The High Speed Analog Unit U8976 boasts the highest sampling rate in its entire series, an order of magnitude faster than conventional models, enabling the unit to perform isolated measurement at 200 MS/s. Thanks to its overwhelmingly fast sampling speeds, the unit can accurately acquire changes in high-speed signals so that you can capture momentary phenomena.

Frequency band and isolated performance that let you accurately capture high switching frequencies

The MR6000 provides isolated channels that can accept 400 V DC direct input while maintaining high-speed sampling at 200 MS/s, allowing it to accurately capture switching waveforms in evaluation testing of inverter and power supply designs that are required to deliver high levels of efficiency. Smooth operation lets you read trace values simply by flicking the flicking the cursor to the side.

Completely isolated input

Connections between analog input channels, and between the input channel and the main unit, are fully isolated. This means that, unlike an oscilloscope, measurements can be made without concern with negative effects from potential differences. << Optical isolation devices (HIGH SPEED ANALOG UNIT U8976)　

Save Time Reduced to 1/30th

Transferring very large amounts of data measured over a long period of time used to be very time-consuming. The MR6000 features a brand new interface and faster internal processing, reducing the time required to save measurement data to media. For example, a save operation that took 1 minute on the previous model now completes in 2 seconds. This saves you the trouble of waiting for data to be saved and improves work efficiency.

Long-term recording and high-speed sampling in multiple channels

The real-time save function controls the available measurement duration without relying on the capacity of the internal memory. For long-term recording, we recommend a high-capacity SSD or HD unit. You can also use a more convenient USB memory stick or SD memory card. All phenomena can be recorded at a high sampling rate over a long period of time. 《Saving data directly to your PC》 Transfer measurement data directly to your PC by using the FTP sending function together with the real-time save function. This makes it easier to observe data after the measuring process.

An Extensive Line of Units for Detecting a Wide Range of Phenomena

Combine multiple units to record a range of phenomena. Use multiple logic units to measure relay ON/OFF signals or PLC (programmable logic controller) signals across up to 128 channels simultaneously. You can also measure temperature by attaching a thermocouple to a temperature unit. 《Unit selection guide》 HIGH SPEED ANALOG UNIT U8976 ANALOG UNIT 8966 4CH ANALOG UNIT U8975 4CH ANALOG UNIT U8978 HIGH RESOLUTION UNIT 8968 DC/RMS UNIT 8972 HIGH VOLTAGE UNIT U8974 DIGITAL VOLTMETER UNIT MR8990 3CH CURRENT UNIT U8977 CURRENT UNIT 8971 TEMP UNIT 8967 STRAIN UNIT U8969 FREQ UNIT 8970 CHARGE UNIT U8979 LOGIC UNIT 8973 See the “Options” tab of the MR6000 webpage for more information about units.

High-sensitivity, high-precision, broadband current probes and sensors

《Current probe》 Analyze minuscule current waveforms from low-power consumption devices in 100 μA resolution. Record device current consumption waveforms in high resolution over extended periods of time. Additionally, the optional Probe Power Unit Z5021 can supply power to current probes from the MR6000. 《Current sensor》 Clamp-type high-accuracy sensors deliver excellent temperature characteristics, allowing highly accurate measurements to be made even in the confined space of a vehicle’s engine compartment. The 3ch Current Unit U8977 lets you connect current sensors directly, allowing the MR6000 to power them and scale readings automatically.

CAN/CAN FD Measurement

CAN buses carry not only control information, but also sensor information required by the ECU for control purposes. Analog values for sensor input signal quantities such as voltage, strain, temperature, flow rate, RPM, torque, vehicle speed, and vibration can be measured at the same time as these signals. 《Capture all data on the CAN bus during measurement》 The MR6000 captures all frame data on the CAN or CAN FD bus during the set recording time. After measurement, you can specify the signals you wish to check and display them on the screen.

Calculate measurement data during measurement (Real-time waveform processing) *MR6000-01 feature

The MR6000-01 further features powerful technology designed for robust real-time waveform processing. This function performs the four arithmetic operations (addition, subtraction, multiplication, and division), differentiation calculations, or integration calculations during the measuring process, letting you use check the calculated results via waveforms while measuring or apply triggers during monitoring. Results can be further processed after measurement and saved.

Observe clear waveforms without noise (Digital filter calculations) *MR6000-01 feature

Remove harmonic noise or specific frequency noise from measurement data. Use it to eliminate the noise that cannot be resolved with the standard filter installed in the unit.

Triggers that detect targeted events

Set triggers on any channel to record data whenever an event occurs. Triggers can be set for all channels. Level trigger : Compares to one voltage value. Window trigger : Compares to two voltage values. Voltage drop trigger : Detects voltage drops in commercial power lines. Period trigger : Monitors periods. Glitch trigger : Detects anomalies in pulses. Pattern trigger : Compares when the logic signal is ON/OFF.

Observe fluctuations for extended periods of time without reducing the sampling rate (Envelope function)

The system uses the envelope measurement method to record maximum and minimum values at set intervals while performing oversampling at 100 MS/s. The internal memory has a capacity of 1 G-words, which ensures that the measuring process can continue for a long time without any data loss. Save data in real time while measuring.

Measure anomalies during extended testing with high-speed sampling (Dual sampling function)

In vibration testing, it's necessary to record comprehensive test data for several hours. At the same time, it’s necessary to capture areas of the waveform where anomalies occur with high-speed sampling for analysis once measurement is complete. The dual sampling function is useful in such situations. (1) Record the entire trend waveform Use the envelope function to record comprehensive test data for several hours. (2) Check details with the instantaneous waveform Anomalies occurring during the test will be captured with high-speed sampling based on triggers that have been set up in advance. By tapping on a trigger mark’s number, you can display the instantaneous waveform for the anomaly that occurred at that waveform area.

Display Functions

《Scroll function》 You can use the scroll function to check the waveform as if viewing it on paper. 《Zoom function》 The zoom function allows you to display all measurement waveforms on a single screen, in the manner of an oscilloscope, and to view desired locations in greater detail. 《Sheet function (display group)》 Switch among 16 sheets to analyze the waveform from various perspectives.

Easily search for waveforms in huge volumes of measurement data

The Memory HiCorder Concierge function automatically calculates the characteristics of a reference waveform set by the customer and then searches all measured data while identifying waveforms that do not resemble the reference waveform as anomalous waveforms. This drastically reduces the amount of time required to search for anomalies by eliminating the need to scroll through measured waveforms and checking them visually. Additionally, this function is ideal for situations where it is difficult to set the right triggers before measuring because the nature of potential anomalies cannot be predicted.

Numerical calculation function

By performing numerical calculations on measured waveforms, you can perform analyses using numerical parameters. Not only analog channels and logic channels, but also results of the real-time waveform calculation function can be used in this calculations. 《Calculating switching times measured using logic channels (t1, t2, t3, T) 》 You can calculate time differences by applying numerical calculations to signals measured using logic channels. 《Calculating the time that elapses until a reading falls from the maximum value to a defined level (50 V) after a capacitor is charged during capacitor charge/discharge testing》 You can calculate the desired value by calculating the time at which the maximum value occurs and the time at which the specified level occurs using numerical calculations and then performing your desired arithmetic operations. 《Calculating the motor inrush starting current time (t1) 》 You can derive the desired time by calculating the burst width using numerical calculations.
