Capture High- to Low-Voltage Signals in a Single
Device! Rugged, Professional and Ready for the Field
Exclusive Academic Offer

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.

Model No. (Order Code)

MR8880-204ch, printer unit option, English model

Note: Input cords and Battery Pack are not included.
Purchase the cords appropriate for your application
separately. Printer Unit MR9000 is optional and sold

Key Features

• CAT III 600V isolation performance; directly measure a 480V power line
• 4 completely isolated channels let you simultaneously record data on a 3-phase power line plus have one extra channel
• Tough against harsh environments; -10°C to 50°C operating temperature range
• Built to withstand mechanical shocks and vibrations (ships standard with side protectors)
• Make settings easily with PRESETS function

How to Use Hioki Memory HiCorders: Measuring Current Waveforms

Watch this video to 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.

How to Use Hioki Memory HiCorders: Recording PLC Timing

Watch this video to learn how to use logic probes to analyze the timing of control signals via the 8 logic and 4 analog channels built-in to the Hioki MR8880. Based on the AND / OR settings, the MR8880’s trigger will activate with respect to the specified logic level. Pre-trigger settings let you capture details about the situation before and after the trigger is activated.

How to Use Hioki Memory HiCorders: Recording Voltage Drop During a Power Outage

Watch this video to learn how to easily detect when a voltage drop on the commercial power supply will occur by using the trigger function on a Hioki Memory HiCorder and setting the peak waveform level as the voltage level. The waveforms can also be automatically printed onsite and saved to portable external media for later analysis on a PC.
