Inside this section the meter permits to perform basic and advanced selections relative to
the type of electrical installation under test. In particular it is possible to:
 Select the type of system, the frequency, the kind of current clamp, the full scale of
current clamp and the VT ratio of external voltage transformer which can be connected
with meter (Analyser Configuration).
 Setting the Manual mode for the customisation of full scale on graphic screen of Real
Time section, the type of harmonic to be shown on screens, the percentage or absolute
values of harmonics, the harmonics zoom, the average calculation of voltages,
currents, active and reactive powers (Advanced Settings).
We suggest the use of smart icons and in order to perform a complete interaction with
the meter.
5.3.1. Analyzer
Configuration screen
Inside the “Analyzer configuration” section a screen depending on the type of system
selected by user during the last operation is shown by meter: The instrument is granted
for a correct measurement only in connection with the following electrical systems:
 Three phase system 4-wire WYE (three phase + neutral + ground).
 Three phase system 3-wire DELTA (three phase + ground).
 Three phase system 3-wire ARON DELTA (three phase + neutral + ground).
 Single phase system (phase + neutral+ ground).
Below the possible screens of above systems’ options are described:
