Description

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.

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

■ Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)

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)
