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.
| 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 |
| 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 |
| Dimensions and mass | 298 mm (11.73 in)W × 224 mm (8.82 in)H × 84 mm (3.31 in)D, 2.4 kg (84.7 oz), (excluding input units and the Battery pack Z1003) Reference data: 3.47 kg/ 122.4 oz (including the MR8901 ×4 units and the Battery pack Z1003) |
| Included accessories | Instruction manual ×1, Measurement guide ×1, AC adapter Z1002 ×1, Protection sheet ×1, USB cable ×1, Shoulder strap ×1, Application disk (Wave viewer Wv, communication commands table, CAN Editor) ×1 |
