Measurement in the field

  • Enhanced usability
    Shorten setup time with virtual amplifier setup screen and AUTO button
  • Direct input sensors
    Directly input voltage, strain, temperature, vibration, pressure or rotational pulse signal with 11 types sensors inherited from the RA1000 and RA2000 series.
Measurement modes
  • Pen recorder mode
    Pen recorder mode is used to output data to chart paper directly. This mode shows pen-written waveforms on the screen. Amplifiers and chart speed can be set similar to a chart recorder.
  • Paper feed speed: 100 mm/s to 1 mm/min
  • Recording resolution (time axis): 20 to 80 dots/mm
  • Recording resolution (amplitude axis): 8 dots/mm
  • HD recorder mode
    HD recorder mode saves data to a 160 GB HD or 256 GB SSD for long term storage. One microsecond sampling is possible when only 1 channel is used. When all 16 channels are used data can be recorded every 10 µs.
  • Continuous recording
    Data is recorded to two gigabyte chunks. When more than two gigabytes is recorded another chunk is created and recording continues. Previously recorded data can be viewed during measurement. Moreover, this also limits damage caused by file corruption caused by power outages, etc. during recording.
  • Sample data and peak data
    The Omniace is a digital recorder that converts analog input signals for storage as digital data. Error is introduced to the recorded data due to the relationship between the speed of this AD conversion and the frequency component of the input signal.
    When the Omniace records an input signal, it is possible to record high frequency noise independent of the print speed. Additionally with the HD recorder, data can be stored to a hard disk for analysis.
    • Sample data
      With this method, raw data is faithfully recorded at the designated recording speed (every 10 ms in this example).
    • RA2300MKII Exterior
    • Peak data
      Sampling is performed at the maximum sampling speed over the set recording interval (10 ms in the example) and the maximum and minimum values are recorded. This allows compression of data without losing peak values. However, peak data requires twice the recording capacity of the sample data method.
    • RA2300MKII Exterior
  • Data looping
    Data can be looped endlessly when recording over uncertain timeframes with unpredictable anomalies. With this function the most recent data is always stored to the hard drive.
  • Reduce recording paper costs
    Two gigabytes can hold two-hundred and nine 30 m recording paper rolls.
  • Memory recorder
    Record data at high speeds (up to 1μs) to internal memory (2 mW/ch). Memory from unused channels can be used for up to 32mW recording on one channel. Additionally, various measurement conditions can be set with trigger functions.
    Data input to memory can be output to recording paper or other storage device.
  • Sample rate: 1 μs to 100 s (depends on the input device)
  • Memory capacity: 2 megawords/ch
  • Memory divisions: 1-128
  • Recording operations
    By partitioning the memory block, it is possible to repeat multiple recordings.
    • One time
      Data is recorded until a single partition is full. ※Full use of recordable time on partition
    • Repeated
      Data is recorded until all partitions are full.
    • Endless
      After recording data over all memory blocks, data is overwritten from the beginning. Recording ends with the stop key.
  • Pre-trigger functions
    • Trigger modes
      • OR - Recording begins when any trigger conditions are true
      • AND - Recording begins when all trigger conditions are true
      • WINDOW - Recording begins when the signal level of the specified channel falls within the set range (IN) or when it deviates from the range (OUT).
    • Pre-trigger (only in memory recorder mode)
      With this function a trigger point is set as a boundary and data leading up to the trigger point can also be recorded. Data can be recorded before and after the trigger point which is set as a percentage of the full memory capacity of the block. The example shows the pre-trigger set to 25%. In this case data before the trigger event will be saved to 25% of the memory capacity of the block.
  • Multi-recorder mode
    Multi-recorder mode enables simultaneous recording to paper output, hard drive and memory.
    It is possible to record sudden phenomenon to the memory while recording on the chart paper or to the HDD or SSD.
  • RA2300MKII Exterior
  • X-Y Recorder
    This mode records input signals from selected channels on an X-Y chart (X-axis: 1 channel, Y-axis: 3 channels). Output can be printed to chart paper at high resolution (1600 dot x 1600 dot).
Replay Display Function
  • Search large amounts of data quickly
    The RA2300 MKII is equipped with functions to search large amounts of data quickly.
  • Thumbnail bar
    The waveform image of the recorded data for one selected channel can be displayed on the thumbnail bar. This data is easy to read and can be expanded by touching the point you want to see in greater detail.
  • RA2300MKII Exterior
  • Jump search
    The four methods below can be used to search data.
    • Time - Jump to a specific time.
    • Address - Jump to a time from the start of measurement.
    • Significant point - Jump to the maximum and minimum values.
    • Event - Jump to the marks made during recording.
    • RA2300MKII Exterior
  • Numeric display of waveforms
    Scale, signal name, numerical value and/or time interval can be displayed for waveforms between the 2 cursors on the replay monitor. RA2300MKII Exterior
Useful features
  • Shutdown
    Memory data and measurement conditions are automatically saved to the hard drive when the device is turned off. This information is automatically loaded from the hard drive the next time the device is started so measurement can begin with the same settings.
  • Easy setup
    Up to 4 measurement conditions can be saved. Measurement conditions can be saved for each test, eliminating the need to make complicated configurations each time.

  • Timer
    Automated measurements are performed at specified times and intervals. RA2300MKII Exterior
  • CSV file conversion
    The RA2300MKII can output files in CSV format for processing measurement data with spreadsheet or analysis software. It is equipped with functions to reduce measurement data size or convert large amounts of measurement data at once.
Connecting PCs or peripherals
  • PC connection
    The RA2300 can be controlled remotely via Ethernet connection to a PC. You can use Unifizer NS3300 (optional software) to record data, configure settings and start recording. RA2300MKII Exterior
  • Sharing files with a PC
    File sharing with a PC via Ethernet is possible. You can transfer the recorded data to your PC. RA2300MKII Exterior
  • High-capacity data storage
    File sharing with a PC via Ethernet is possible. You can transfer the recorded data from your PC.
  • Measures against power failure during long-term recording
    When the RS2300MKII is connected to an uninterruptible power supply (UPS), the shutdown procedure will be performed automatically during a power failure. If a power outage occurs during long term recording, the recording operation can be terminated by a signal from UPS and the RA2300MKII can be turned off.
    ※Optional RS232C unit or remote unit is required
