The Yokogawa CW500 is a portable power meter that utilizes current clamp-on probes, navigation screens and quick start guides to enable user friendly power consumption and power quality measurements in the field that conform to IEC61000-4-30 Class S.

The CW500 has a simple and direct navigation screen for setup of connections and detail settings. Stored measured data is easily accessible through the PC software by use of an SD card or USB connection to the PC. The CW500 is available with or without Bluetooth.

The Yokogawa CW500 power quality analyzer is loaded with advanced diagnostic features including: power measuring and logging (1-phase 2-wire to 3-phase 4-wire), power quality measuring (voltage swell, voltage dip, voltage interruption, transient overvoltage, inrush current, harmonics and flickers), user support (start guide function and automatic detection of current clamp probe), and data analysis and report generation (automatically create graphs and reports of measured data by a single click).
