Touch Screen
for Intuitive Operation
Touch screen interface improves operating
efficiency
Buttons on the MR8875 are kept to a minimum by utilizing touch
screen technology. The high-definition 8.4-inch high-brightness TFT
color LCD is the interface of choice for improving productivity by
offering a more intuitive experience than traditional input methods.
While the connection terminals are located at the top panel of the
MR8875, when cables need to be connected from the bottom, simply
swipe the screen from top to bottom at either edge and the screen
will rotate correspondingly. The MR8875 can be set in a position that is
easier to use according to the installation location.
Touch to scroll back or scale the waveform
Display earlier waveforms during recording without stopping measurement by simply touching the scroll icons on the screen. You can also scale
the waveform amplitude by just swiping through the waveform up (to
zoom in) or down (to zoom out).
Advanced cursor read function for multichannel
analysis
Six cursors A, B, C, D, E, and F are available, compared with the
conventional A- and B-cursors.
Use the cursors to measure and display the following:
• A, B, C, and D: Potential and time from the trigger
• E and F: Potential
• A-B and C-D cursors: Time difference and potential difference
• E-F cursors: Potential
Split screen, sheet display, event mark input, and
jump functions indispensable for efficient analysis
Split screen and sheet display functions are provided to support
multiple channels. Individual display formats can be selected and
an application can be assigned to each sheet for analysis, increasing
productivity.
H For long-term recordings, tag important points with event markers. Up to 1000 markers can be placed so that you can quickly jump
to them later for detailed analysis.

Powerful Data Analysis Capabilities
FFT Analysis Function
MR8875 Ver. 2.01 or later
Simultaneously measure four phenomena
The MR8875's FFT analysis function can simultaneously analyze
four phenomena with a single measurement.
By performing FFT analysis of different signal inputs from channels 1 through 4, it is possible to analyze the frequency components of each channel occurring at the same time.
Additionally, you can simultaneously view the linear spectrum,
RMS spectrum, power spectrum, and phase spectrum for a signal
input to channel 1, for example.
Analysis functionality for a variety of
measurement scenarios
The MR8875 features calculation functions that are often used
during field measurements. The linear spectrum is used in analysis that focuses on waveform amplitude values, while the power
spectrum is used in analysis that focuses on energy, for example
noise and vibration measurement. You can select the calculation
function that best suits your application— for example, use a
transfer function for measurement that identifies internal systems based on I/O characteristics.
Peak value display function (marker display)
The peak value display function can be used to search for maximum and local maximum values and then display them. Characteristic values can be easily displayed even without using a cursor.
Since the MR8875 stores up to 200 frames (200 calculation results)
of data, it will automatically search for the peak value again if a
different frame is selected.
Running spectrum display function
The MR8875's running spectrum display function can be used to
continuously display spectra that change over time. Up to 200
frames* of the most recent calculation results can be stored.
Although Hioki's MR8847 Series only supports running spectrum
display for certain types of calculations, the MR8875 can generate
this display with all FFT calculation functions. Additionally, if the
selected frame is changed, the cursor value can also be loaded.
* Frame data is stored in the instrument's internal memory, regardless of whether the running spectrum display is used.
The MR8875 can also freeze the spectrum display on its screen
during measurement. This function allows data to be observed
without the inclusion of unneeded information on the screen or in
the data. All calculation results can be output as CSV data, which
can be loaded into a spreadsheet application such as Microsoft
Excel and used to create a three-dimensional graph.
Example of data displayed with Microsoft Excel
9
Extensive window functions
The MR8875 provides a total of seven window functions, including rectangular and Hanning variants. The rectangular function is used for
analysis that focuses on spectrum amplitude values, while the Hanning function is used for analysis that focuses on the degree of spectral
separation of frequency components. Additionally, by using an exponential window in impact measurement utilizing an impulse hammer, the
instrument enables more precise analysis by limiting unneeded noise components on the time axis.
Continuous calculation function
Number of skips
When analyzing a signal that changes over time, the number of
FFT calculation points becomes a limitation, preventing the waveform from being analyzed in all time domains. Furthermore, us-
Time waveform
ing too many FFT points prevents the desired results from being
obtained because the spectrum is averaged. The MR8875 resolves
these problems with its continuous calculation function. For data
covering extended periods of time, calculation points can be
shifted by a number of skip points* at a uniform interval. More-

over, calculations for up to 200 frames can be accomplished with
a single operation. Calculation results for different time periods
can be reviewed by changing the calculation frame, regardless of
whether you're using the running spectrum display or a singlescreen display.
* The number of skip points can be set from 100 to 10,000.
Overlay display function
The MR8875's overlay display function can be used to observe
variations in waveforms captured using continuous measurement
over time. Although previous Hioki models have not been able
to overlay FFT calculations, the MR8875 offers this capability, improving the visibility of analysis.
Visually appealing screen displays
The MR8875's display can be switched according to the applica-
Single-screen display
tion at hand. For example, its single-screen display can be used
when focusing on the correlation between channels, while its
four-screen display can be used to isolate complex spectra for
viewing. Additionally, time and spectrum waveforms can be displayed above and below one another when focusing on correlation with a captured time waveform.

* Finite impulse response (FIR) and infinite impulse response (IIR) digital
filters are offered. LPF (passing only the low-frequency component), HPF
(passing only the high-frequency component), BPF, and BEF (passing or
rejecting only a frequency bandwidth of a certain width) variants of each
can be configured.
* Although FIR calculation processing is time-consuming, it can yield waveforms with no phase distortion. By contrast, IIR calculation yields results at
a relatively faster calculation speed but is prone to phase distortion. Each
filter's cutoff frequency is use-specified.

CAN Signal Input
for Vehicle Testing
Synchronized mixed recording of CAN data and real data
such as voltage, temperature, or distortion signals
CAN bus signals that are used widely, particularly in automotive
applications, can be recorded, analyzed, converted to analog waveforms, and viewed. Simultaneous recording and viewing of analog
waveforms from sensors, in addition to the CAN data, allows you to
check the impact of noise and level changes on the communication
data.
Vector’s CAN database can be loaded using
supplied software
Industry standard CANdb® database files can be loaded into the
supplied setting software and associated to the CAN channel signals.
CAN messages can be viewed using the customer-specified message and signal names, as well as scaled engineering units. Since
parameters such as signal data type, start bit, length, and byte
sequence are all pre-defined in CANdb, users can concentrate on their
measurement tasks without needing to define signals.
CAN editor (bundled software)
Withstand extreme environmental temperatures,
vibrations, and data loss due to power outages
In road tests, extreme environmental conditions associated with the temperature and vibration are harsh for measuring instruments. The MR8875 has
the wide operating temperature range of -10˚C to 50˚C and is compliant with
the JIS DI1601 standard for vibration resistance performance. It is designed to
withstand the harsh conditions for in-vehicle measurement.
In the event of a power outage while data is being recorded, the power supply
is maintained using a built-in large-capacity capacitor until data is completely
written to the SD or USB memory. Risk of data loss or damage to the file system is minimized, and after power is restored, measurement can be restarted
automatically.
