5. INITIAL SETTINGS
CAUTION
The instrument may be configured only through the relevant management
software, except for the selection of the electrical system, which may also be
performed through the SYSTEM key in the instrument's keyboard
5.1. SETTING THE ELECTRICAL SYSTEM
This parameter allows selecting the type of electrical system to be analyzed. It is possible
to select the electrical system through the SYSTEM button in the instrument's keyboard.
Following configurations are available:
Single-phase system
Three-phase system without neutral (3-wires)
Three-phase system with neutral (4-wires)
Each electrical system is associated with a list of parameters automatically recorded by
the instrument (not modifiable).
