7.1.1. Type of electrical system under test
This parameter allows to select the type of electrical system under test among the
following configurations:
 SINGLE: single-phase system
 3PH3W:
3-wire system (three-phase system without neutral)
 3PH4W: 4-wire system (three-phase system with neutral)
The connections to the instrument inputs will have to comply with the selected type of
system.
Position the cursor on the corresponding word by pressing the multifunction keys F1 and
F2 and set the desired value by pressing the multifunction keys F3 and F4.
7.1.2. How to set the fundamental frequency
Position the cursor on the corresponding word by pressing the multifunction keys F1 and
F2 and select the network frequency between the possible values 50Hz and 60Hz by
pressing the multifunction keys F3 and F4. This parameter is important ONLY if the input
voltage is not sufficient to recognise the value of the frequency (for example, only the
clamps for the current measurement are connected). In this case the instrument generates
an internal synchronism equal to the value of the set frequency.
