Tính năng Máy phân tích chất lượng điện Fluke 1750:

• Power quality that meets the standard: All measurements comply with IEC61000-4-30 standards for correct evaluation of all measured values including voltage, current, power, harmonics, flicker etc.
• Quick and reliable configuration: ARCHOS 43 Internet Tablet provides a window into what the instrument is recording, enabling quick and reliable configuration even in awkward test locations
• Threshold-free set up: Apply thresholds after data is collected with Fluke Power Analyze Software – no need to worry about missed information due to incorrect setups
• Captures everything: Cross-channel and current triggering capture every measurement, on every channel, every time
• Intuitive PC software: Easily analyze data and generate reports with automated EN50160 reporting and compliance
• Reporting has never been easier: Auto Report creates either standard reports or customized reports with the minimum effort or hassle. 
• Plug and play: Set up in minutes with self-identifying current probes and single-lead voltage connections
• No need to reconnect wires: Swap channels internally with the wireless PDA or PC when connections are not correct
