HIOKI MR8875 Portable Modular Memory Recorder
The HIOKI MR8875 is a memory recorder for high-speed waveform monitoring and recording. The device 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 GND. The MR8875 is a portable and modular system using 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. The MR8875 is the main unit, individual I/O channel configurations can be achieved with a choice of 5 I/O unit/modules types.
- Memory recorder main unit MR8875 with 4 slots in handheld portable design.
- Choice of 5 functional I/O units.
- 1000 V direct input and instantaneous DC or RMS waveform measurement with analog unit MR8905.
- Multi-channel logger capable of thermocouple temperature measurement up to 60 channels at 10 ms intervals.
- Measure multiple channels simultaneously.
- Max. 2 µs 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.
- Interfaces: LAN, USB 2.0, SD card slot.
- Rugged against vibrations and extreme temperatures, ideal for in-vehicle testing and road tests.
Model Overview
| Model | MR8875 |
| 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...10 V/div , 11 ranges (when using the MR8901), 500 mV...50 V/div , 7 ranges (when using the MR8905), resolution: 1/1250 of range |
| Max. rated voltage | Between terminals: 150 VDC; between terminal to earth: 100 VAC, DC (when using the MR8901) |
| Frequency characteristics | DC...100 kHz (-3 dB, when using the MR8901) |
| Time axis | 200 µs...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 MWords, 8 MW each input unit (note: 1 Word = 2 Bytes, therefore 32 Mega-Words = 64 Mega-Bytes. Storage memory can be allocated depending on the number of channels used at each input unit. Removable storage: SD card slot, USB 2.0 memory |
| Display | Touch-panel operation 8.4"/21.3 cm SVGA-TFT color LCD (800x600 dots) |
| Communication interfaces | LAN: 100BASE-TX (DHCP, DNS supported, FTP server/client, web-server, send e-mail, command control); USB 2.0 (1x mini-B receptacle: Setting/measure with communication command, or file transfer SD card to PC; 2x A receptacle: USB memory, USB mouse/key-board |
| Power supply | AC adaptor Z1002; battery pack Z1003; external DC power 10...28 VDC (special cable on request) |
| Dimensions (mm) | 298 x 224 x 84; 2.4 kg (main unit without input units and the battery pack Z1003); 3.47 kg (including 4x unit MR8901 and battery pack Z1003) |
| Third party software support | LabVIEW and MATLAB script support available for MR8875 |
Included: HIOKI MR 8875, instruction manual, measurement guide, AC adaptor Z1002, protection sheet, USB cable, shoulder strap, application CD (Wave viewer Wv, communication commands table, CAN editor). Note: Test leads and I/O units are not included. Purchase the leads and units appropriate for your application separately. AC adaptor Z1005 is included as standard.
