Measures - LEGRAND DPX3 250 Installation Manual

III – Measures :
The ALPTEC controller provides a set of measurements on the alphanumeric display, in
conjunction with the cos phi which is always displayed on the main screen.
The key allows access to different measures which you can find the detail below :
