Product overview: Fluke 120B Series Industrial ScopeMeter handheld Oscilloscopes
Simplified testing, more insightThe compact ScopeMeter® 120B Series, is the rugged oscilloscope solution for industrial electrical and electro-mechanical equipment troubleshooting and maintenance applications. It’s a truly integrated test tool, putting the functions of an oscilloscope, multimeter, and high-speed recorder into one, easy-to-use instrument. The ScopeMeter 120B Series also integrates with Fluke Connect® mobile app and FlukeView® for ScopeMeter software to enable further collaboration, data analysis, and archiving of critical test information.*Not all models are available in all countries.

Voltage and current unbalance
Check the voltage unbalance at the input terminals of the frequency speed drive so you can ensure the phase unbalance is not too high (> 6-8 %), and that the phase rotation is correct. You can also check the current unbalance, as excessive unbalance may indicate a drive rectifier problem.
Extended harmonic measurements
Excessive harmonics are not just a threat to your rotating machines but also to other equipment connected to the electrical power system. The MDA-550 provides the ability to discover the harmonics of the motor-drive but can also discover the possible effects of inverter switching electronics. The MDA-550 has three harmonic ranges, 1st to 51st Harmonics, 1 to 9 kHz and 9 kHz to 150 kHz giving the ability to detect any harmonic pollution problems.
One of the interesting aspects of the publication is its emphasis on Predictive Maintenance (PdM). While Chapter 5 defines, explains, and provides comparisons and examples of maintenance program types, the guide devotes an entire chapter (Chapter 6) to PdM. Three of the PdM technologies presented in the guide include thermography , vibration analysis, and performance trending. I’ll come back to this.
