    Power Quality Analysis With the help of powerful digital signal processing technology, the Acuvim II intelligent power meter can be used as an online power quality analysis instrument. It can simultaneously and continuously give out the analysis results such as THD of voltage and current, harmonics up to 31st order and unbalance factor of voltage and current, etc.
  • Page 12 Easy to Use With a large high density LCD screen, the display of the Acuvim II is easy to read and use. All the measuring data and setting parameters can be accessed by using panel keys or a communication port. The setting parameters are protected in EEPROM, which will maintain its content after the meter is powered off.
