Powerful Troubleshooting Capabilities
The Fluke 430-II products were specifically designed with the needs maintenance engineers and technicians in mind; users who need to get to the solution of the power quality problem as quickly as possible so that they can minimize expensive downtime. The measurement process and display of data is optimized to get to the most important information as quickly as possible. Multiple parameters are measured simultaneously and displayed in formats that quickly describe the state of the power quality of the system. Data can be quickly accessed as simple digital values, trend graphs, waveforms, phasor diagrams or analyzed and organized into tabular format such as the event data where the magnitude, duration and time stamping enable rapid correlation to problems experienced.
