The Dranetz PowerGuide® 4400 is a portable, hand-held, eight-channel power quality meter/monitor. This cutting-edge power quality instrument is designed with a color liquid crystal display (LCD) 1/4 VGA, using touch screen technology. It can monitor, record and display data on four voltage channels and four current channels simultaneously.The 4400 is designed to meet both the IEEE 1159 and IEC 61000-4-30 Class A standards for accuracy and measurement requirements. It can also monitor EN50160 compliance based on the EN (European) Standards. The statistical package called Quality of Supply (QOS) is built into the 4400, with monitoring and setup protocols set to determine voltage measurement compliance required for EN50160 monitoring. European standard EN50160 requires that measurement parameters must be within a specified percentage for 95% of the time.
