In this video, learn how to capture random events on The Fluke 190 Series ScopeMeter® Portable Oscilloscope.
The Fluke ScopeMeter 190-204/S combine the highest safety ratings and rugged portability with the high performance of a bench oscilloscope. Designed for plant maintenance engineers and technicians, these tough ScopeMeter test tools go into harsh, dirty, and hazardous industrial conditions to test everything from micro-electronics to power electronics applications.
The ScopeMeter 190-204/S is the one test tool you will reach for to tackle just about any troubleshooting task. They include a multimeter, TrendPlot™ and ScopeRecord™ roll paperless recorder modes and hands free operation with Connect-and-View™ triggering, and much more:
• Four electrically isolated inputs
• 200 MHz bandwidth model
• 2.5 GS/s
• Deep memory: 10,000 samples per channel waveform capture so you can zoom in on the details
• Connect-and-View continuous auto-trigger, single shot, pulse width, and video triggering
• ScopeRecord roll mode, capture waveform sample data for up to 48 hours
• TrendPlot, trend measurement readings for up to 22 days
• Advanced automatic measurements, power (Vpwm, VA, W, PF) and time (mAs, V/s, w/s)
• IP-51 rated for dust and drip proof to withstand harsh environments

So... I can see a change in the phase angle height but the amplitude of the rest all seem the same...?

Hi there - Thanks for the question. Note that these signals were simulated, so the way these phases react may not be how a three-phase system would act. Also note that the voltages of each phase are around 6V-7V, which is not the typical voltage for a three-phase power system. In this demonstration there was a simulated decrease in voltage on phase A and an increase in voltage on phase C. There was no change in voltage simulated in phase B. The fourth channel was actually the phase difference between phase A and C (not A and B as stated in the video). You can tell by looking at each individual channel that phase A had a smaller decrease in amplitude than phase C, which had a greater increase in amplitude, so one would expect to see a small increase in the difference between phase A and phase C, which was indeed the case. Please let us know if you have any additional questions. Thanks!
