In Detail:
The MR8848 Memory Recorder is a modular, high-speed data acquisition system designed
for accurate waveform recording under demanding conditions. Its rugged construction and
shock-resistant housing make it suitable for both field and lab environments, especially
where vibration, temperature fluctuations, or harsh handling are expected. With a buttonoperated interface and robust design, the MR8848 is intended for long-term, real-world
testing where reliable performance is essential. The system features eight input slots and supports a broad range of interchangeable
modules, offering flexibility for various measurement scenarios. It can simultaneously record
multiple physical parameters – including voltage, current, logic, temperature, vibration,
pressure, and strain – facilitating comprehensive analysis of complex systems. Users can
configure the system for either simultaneous isolated measurement on up to 32 analog
channels, or for high-speed acquisition at up to 20 MS/s, depending on the selected
modules. For high-voltage measurements, another specialized module enables direct input
up to 1000 VDC or 700 VAC. The MR8848 enhances flexibility by enabling direct connection
to HIOKI’s high-accuracy current sensors. Wideband current probes like the CT6711 can be
used together with analog modules such as the U8978. Dedicated current modules, including
the U8977 and 8971, provide accurate measurements across a broad current range and are
designed to work effortlessly with precision clamps and sensors like the CT6841A or
CT6904A. These specialized current modules automatically detect and supply power to
connected HIOKI sensors and clamps, making setup simple and efficient.
Four built-in logic inputs support up to 16 logic channels when used with 4-channel logic
probes. If additional logic channels are needed, logic input modules can be added to further
expand capacity.
Three compatible output modules provide functions such as pulse output and waveform
generation for signal testing and simulation. With the Arbitrary Waveform Generator Module
U8793, users can program and output custom waveforms, making it perfect for replicating
and simulating anomalies. The free SF8000 software makes it easy to create waveforms by
entering data directly and supports tasks like simulating noise or combining waveforms for
complex applications.
To support extended and uninterrupted recordings, the MR8848 features the optional realtime saving function MR9001-01 that enables data to be written directly to the optional 1 TB
SSD or to another external storage, e.g. SD card or USB drive, during measurement. Unlike
conventional systems that rely on internal memory buffers, this approach eliminates the need
to pause testing for data offload, allowing continuous acquisition over long durations. In
addition, real-time saving minimizes the risk of data loss in the event of unexpected power
interruptions, ensuring stable and reliable data logging throughout the measurement process.
The DC Power Unit 9784 is a factory-installed option for the MR8848 Memory Recorder,
enabling operation from external DC sources between 10 V and 28 V – such as vehicle
batteries. This wide input range removes the need for AC power or external converters,
making it ideal for field measurements, mobile testing, and other demanding environments.
Seamlessly integrated during production, the 9784 provides a compact and reliable power
solution for use on the go.
The U8351 Printer Unit is a factory-installed option for the MR8848 Memory Recorder that
enables immediate, tamper-proof printouts of waveform data and measurement results
directly at the test site. It is ideal for applications requiring verifiable hard copies, such as
regulatory documentation, service reports, or customer acceptance records. The printer is
especially useful in environments where digital media are impractical or restricted, providing
fast documentation without needing a PC or USB storage.
Included software tools support a smooth workflow. Use the free MR6000 Viewer and
Waveform Viewer to display, analyze, and export your data with ease. For more advanced
tasks, the 9335 Wave Processor adds powerful processing and batch conversion features.
Integration with LabVIEW, MATLAB, and operation via SCPI commands allows flexible
automation and control.
The MR8848 is widely used across a range of infrastructure and transport sectors, where its
high-speed, multi-channel capability and modular input options make it a powerful tool for
system diagnostics and validation. In electric power systems, it supports UPS operation
testing, ensuring reliable backup activation by recording voltage, current, and temperature
behavior across both input and output sides. In hydropower generation, it enables detailed
load rejection testing, capturing multiple signals such as turbine speed, generated current,
and water pressure to verify that the turbine shuts down safely after a sudden load drop.
For high-voltage circuit breaker testing, the MR8848 precisely measures the time difference
between command signals and contact response across all three phases, helping identify
switching delays and ensuring timing compliance. In the railway sector, it records drive motor
voltage and current, vehicle speed, brake pressure, and vibration during actual operation,
making it a key solution for correlating multi-parameter behavior and validating safety-critical
subsystems.
