Description:
The Fluke 434-II Energy Analyzer and 435-II Power Quality and Energy Analyzer are designed to help you minimize downtime, quickly troubleshoot power quality issues and easily discover the costs of wasted energy. Downtime is expensive and getting the data you need to solve to critical power quality problems quickly is key. The 434-II and 435-II Analyzer’s measurement process and data output have been optimized to help you access the most critical information easily.
Multiple parameters are measured simultaneously and displayed in formats that quickly describe overall power quality health. The detailed information helps you make better maintenance decisions—whether you’re trying to reduce energy waste, find the source of power quality issues or see how motor startups are affecting your electrical system. Data can be accessed as simple digital values, trend graphs (for fast insight into changes over time), waveforms, or phasor diagrams. The data can also be analyzed and organized into tabular formats. Detailed event data allows you to see the magnitude, duration and time stamping of anomalies enabling you to rapidly correlate the problems you are experiencing in your facility.
