8.1.1. How to set the type of electrical system under test
This parameter permits you to select the type of electrical system under test among the
following configurations:
 SINGLE: single phase system
 3PH3W: 3 wires system (three-phase system without neutral)
 3PH4W: 4 wires system (three-phase system with neutral)
The connections to the instrument inputs will have to be in keeping with the type of system
selected.
Position the cursor on the corresponding word by pressing the keys
F1 and F2 and set the
desired value by pressing the keys F3 and F4 .
8.1.2. How to set the fundamental frequency
Position the cursor on the corresponding word by pressing the keys F1 and F2 and select
the network frequency between the possible values 50Hz and 60Hz by pressing the 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.
8.1.3. How to set the current range
The value of this parameter must be always equal to the full scale of the current
clamps used to take the measurement. In case multi-scale clamps are used, the value of
this parameter must be equal to the scale selected on the clamps.
Set the desired value by pressing the keys
F3 and F4 .
