Hioki MR8875 Memory Hi Corder
Hioki MR8875 MEMORY Hi CORDER
1000V Direct Input, Portable 16-channel Memory Recorder for
Data Acquisition During Vehicle Testing with Direct CAN Bus Input
Brand : Hioki (Made in Japan)
Code : MR8875
Key Features
- 1000V input and instantaneous DC or RMS waveform measurement with new Analog Unit MR8905
- Multi-channel logger capable of thermocouple temperature measurement up to 60 ch at 10 msec intervals
- Measure multiple channels simultaneously despite handheld portable design
- Max. 2 μsec high-speed simultaneous logging for all input channels
- Save directly to the SD Card in real time for uninterrupted long-term logging
- 16-bit high-resolution measurement of voltage, temperature, distortion and CAN signals
- FFT calculation, waveform calculation functions for advanced analysis
- Intuitive touch screen for optimal operability
- Tough against vibrations and extreme temperatures, with strengthened body ideal for in-vehicle testing and road tests
- 3 different power supplies
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.
Basic specifications
|
Number of input units |
Up to 4 slots |

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 |
|
Removable storage |
SD card slot ×1, USB 2.0 memory |
|
Display |
Touch-panel operation 8.4-inch SVGA-TFT color LCD (800 × 600 dots) |
|
Communication interfaces |
LAN: 100BASE-TX (DHCP, DNS supported, FTP server/ client, WEB server, send E-mail, command control) USB: USB 2.0 compliant, series mini-B receptacle ×1 (setting / measure with communication command, or file transfer SD card to PC), series A receptacle ×2 (USB memory, USB mouse/ key-board) |
|
Power supply |
1) AC adapter Z1002: 100 to 240 V AC (50/60 Hz), 56 VA 2) Battery pack Z1003: 7.2 V DC, 36 VA, continuous operation time: 1 hour with back light ON (AC adapter has priority when used in combination with battery pack), Charges while installed in the MR8875, recharging time: 3 hours 3) External DC Power: 10 to 28 V DC, 56 VA, (please contact your HIOKI distributor for connection cord) |
|
