Pro Trend 三相电能质量分析仪是先进电力监测仪器，8.4" color touch screen display.可帮助发现、预edict, and troubleshoot problem in three and single-phase power distribution systems. Troubleshooting is faster with on-screen display of trends and captured events. A wide range of 电力监测 data is collected, analyzed and tabulated to quickly identify areas of concern. Automated setups provide instant detection of circuits and configurations, guaranteeing that the instrument is ready to successfully collect data. Pro Trend collects data at 256 samples per cycle per channel, meets IEEE 1159, IEC 61000-4-30 standards. Pro Trend is perfectly suited for field use, having a weather-proof case weighing in at just 4½ kg.
