Waveforms give a graphical representation of what’s happening with your power during a particular moment.
Quickly isolate potential power problems.
Excellent for troubleshooting problems that occur continuously.

28. Disturbance Detection and Advanced Waveform Capture (PM870)
The PM870 has the ability to detect, alarm upon, and capture voltage and current sags and swells that can cause unwanted trips and process interruptions, damage motors and more.
Twelve factory configured voltage disturbance (sag/swell) alarms provide warning and trigger a disturbance waveform capture.
Disturbance alarms can be reconfigured for current sag and current swell using System Manager software.
Voltage sags are often caused by heavy loads being started. The PM870’s disturbance detection features can help isolate the source of troublesome sags and swells.
