2.- ANALYZER MAIN FEATURES
2.1.- Basic features
The AR5 series analyzers are programmable instruments that measure,
calculate and store to memory the main parameters of three phase electrical
supply networks.

Setup: Analyzer’s setting is completed through a system of spreadable menus
that provide a friendly-use and intuitive configuration process.
Data visualization: By means of a liquid crystal graphical display, 160 x 160
pixels and with backlight ability, the user can view instantaneous, maximum and
minimum values of each parameter at each phase.
Internal battery: permits the user to accomplish with analysis works without
the need of an external auxiliary power supply. The analyzer is equipped with an
intelligent battery charging system, which expands the battery life span. For recharge
the battery is necessary to connect the power supplier.
Installation: Analyzer is suitable for analysis works over any type of electric
networks (single-phase, bi-phase, 3-wire and 4-wire).
Measuring: Measurement of average values of main electrical parameters, as
well as, recording of maximum and minimum values. To execute these
measurements, the analyzer is equipped with three a.c. voltage inputs and four a.c.
current inputs (through current clamps ../ 2 V a.c.).
Data collection: The analyzer has a 1 Mb on-board memory to save into all
the parameters measured or calculated by the analyzer, in order to be further
retrieved from a PC.
PC software: together with the analyzer, it is also factory supplied a friendly-
use, powerful software that permits data downloading from the internal memory to a
PC and a further complex analysis of recorded data.
