MR8875 Memory Corder

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 X 1, USB 2.0 memory

Display

Touch-panel operation 8.4-inch SVGA-TFT color LCD (800 X 600 dots)

Communication interfaces

USB: USB 2.0 compliant, series mini-B receptacle X 1 (setting / measure with communication command, or file transfer SD card to PC), series A receptacle X 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)
