Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously measure multiple quick-changing phenomena due to complete isolation between channels and from each channel to the ground. The MR8880 is a data acquisition (DAQ) recorder built in with 4 analog channels that can accept direct input of 600V, enabling measurements of 3-phase systems.

Measuring Current Waveforms: How to Use Hioki Memory HiCorders

Learn how to use the Hioki MR8880’s trigger function to definitively record the startup current when a motor is powered on.

Pre-trigger settings let you capture details about the situation before and after the trigger is activated, and numerical data of the peak current waveform can be easily identified using the built-in cursor functions.

Key Features
