5.2.1. How to set the type of electrical system under test
This parameter permits 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) (see paragraph 16.3.2)
•
3PH4W: 4-wire system (three-phase system with neutral)
The connections to the instrument inputs will have to be in accordance with the type of
system selected.
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 .
5.2.2. 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 recognize the frequency value (for example, only current clamps
are connected). In this case the instrument generates an internal synchronism equal to the
value of the set frequency.
5.2.3. 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 multifunction keys
F3 and F4 .
