FEATURES
For Evaluation Testing and Troubleshooting
Robust Housing
To minimize the risk of failure due to drops and shocks, the Memory HiCorder MR8848 employs a rugged housing with protectors for enhanced durability.
Safe and Reliable Measurements
When inspecting lines of differing electrical systems simultaneously (e.g., power lines and signals), short-circuit are a serious risk. Unlike oscilloscopes, memory HiCorders have isolated channels, so short-circuit accidents will not occur between differing circuits.
Correlation Analysis of Various Physical Phenomena
Troubleshooting and analysis can be more in depth than ever before through simultaneous recording of various physical phenomena.
The Memory HiCorder MR8848 records and analyzes multiple physical parameters—including voltage, current, temperature, vibration, pressure, and strain—for identifying correlations and root causes.
Onsite, Tamper-Proof Printing (Factory-Installed Option)
The factory-option printer lets you immediately print and share tamper-proof hard copies of your measurements right at the site, so that data cannot be tempered with.
Record Long-Duration Waveforms with High-Capacity Storage
Long-term waveform recording becomes possible by storing data on the large-capacity 1 TB SSD (U8334) with the Direct Write to Storage option (MR9001-01).
For example, in railway vehicle measurement, the Memory HiCorder will record over 10 parameters at a sampling rate of 10 µs/S for more than an hour.
