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.
