Advanced LCD Display

New icon type display, with white backlight to ensure good visibility in environments with low light conditions. Scrolling text with 4 characters to show :

  • Alarm messages configured by the user
  • Help messages for the user
  • Description of the setup menu and parameters. The text is available in 5 languages (English, Italian, French, Spanish and Portuguese)

USB and Communication Dongle

Through the optical port, direct connection to a PC USB Optical Module or via WiFi dongle module is allowed. Wifi dongle can furthermore make :

  • Copy of the parameters
    All parameters in the Analyzer can be saved in the Wifi Dongle memory and in case reloaded on the same device (backup function) or on a different one of the same type (replication of the configuration)
  • Clone of the device settings
    In addition to the copy of the parameters, the current values of the energy meters and hour counters can be saved in memory as well, in order to fully replicate a Analzyer on another device of the same type or to restore the Analyzer to a previously saved state.
