1000V Direct Input, Portable 16-channel Memory
Recorder for Data Acquisition During Vehicle Testing
with Direct CAN Bus Input
|Hioki Memory HiCorders are high-speed waveform monitoring and recording|
devices that can simultaneously measure multiple physical phenomena such
as voltage, current, temperature, vibration, weight, acceleration and
rotation due to complete isolation between channels and from each channel
to the ground. The MR8875 data acquisition (DAQ) recorder accommodates
plug-and-play input modules to meet applications such as onboard vehicle
analysis, current consumption testing of portable devices, and measuring
the voltage waveforms of superconducting materials and contacts.

How to Use Memory HiCorders: As a Multi-channel High-speed Data Logger
The Hioki MR8875 revolutionizes data logging by letting you record data to the SD Card in real-time in high speeds. Up to 3 full seconds of data logged in as fast as every 2μsec can be precisely captured, and when recording up to 50μsec of data, you can store up to 60 channels of signals, all in real-time into one single SD Card.
|How to Use Memory HiCorders: Measuring Acceleration using a Strain Unit|
Abrupt fluctuations in acceleration can cause unacceptable motion errors in automobiles, transportation equipment and industrial robots. The Hioki MR8857 Memory HiCorder installed with the strain measurement module can greatly assist in helping you measure and analyze these unexpected acceleration fluctuations across 16 channels. Watch this video to learn how to connect distortion gauge acceleration sensors and make proper settings with the intuitive interface, as well as use the recorder’s scaling function to efficiently record waveforms.
|Performance and Durability Testing|
With its multichannel, long-term recording capabilities, the MR8875 is ideally suited for use in development applications such as performance and durability testing. Record sensor output, evaluate sensors and other devices, and even use as a flatbed X-Y recorder.
|Inverter and Motor Testing|
Install the High-voltage Input Unit MR8905 to easily measure and capture waveforms from the primary- and secondary-side of UPS power supply as well as commercial power supply transformers.
|Number of input units||Up to 4 slots|
|Number of channels||Max. 16 analog channels (Max. 60 channels when using the MR8902) + standard 8 logic channels + 2 pulse channels|
Note: For analog units, channels are isolated from each other and from the MR8875’s GND. For CAN unit ports or standard logic terminals or standard pulse terminals, all channels have common GND.
|Measurement ranges (20 div full-scale)||5 mV to 10 V/div , 11 ranges (when using the MR8901), 500 mV to 50 V/div , 7 ranges (when using the MR8905), resolution : 1/1250 of range|
|Max. rated voltage||Between terminals: 150 V DC|
Between terminal to earth: 100 V AC, DC (when using the MR8901)
|Frequency characteristics||DC to 100 kHz (-3 dB, when using the MR8901)|
|Time axis||200 µs to 5 min/div, 21 ranges, sampling period: 1/100 of range, External sampling possible|
|Max. sampling rate||[When using MR8901] 500 kS/s (2 μs period, all channels simultaneously)|
[When using MR8902] 10 ms (all input channels are scanned at high speed during every recording interval)
[When using MR8903] 200 kS/s (5 μs period, all channels simultaneously)
External sampling: 200 kS/s (5 μs period)
|Measurement functions||High-speed function (high speed recording), Real-time calculation between channels, FFT calculation, or other functions|
|Storage memory capacity||Total 32 M-words (memory expansion: N/A, 8 MW each input unit)|
Note: 1 word = 2 bytes, therefore 32 Mega-words = 64 Mega-bytes.
Note: Storage memory can be allocated depending on the number of channels used at each input unit
