The MAR-715L network power analyzer is fully programmable measuring instrument that measure and record in memory all the electrical parameters from any electric power system. This instrument is equipped with four voltage inputs and other four current inputs to carry out the measurement of any parameter from either balanced or unbalanced three-phase power systems.

Instantaneous readouts are displayed by a 160 x 160 pixels graphic screen, and, simultaneously, these results can be saved in an internal memory according to preset file types. That way, records can include average, maximum and minimum values of voltages, currents and powers, but also wave form snapshots, values of accumulated energy, disturbances, etc.).

The MAR-715L is also a re-programmable instrument, so that, by means of an external cartridge connected to the built-in communication output, diverse operation programs can be loaded or updated in order to accomplish any analysis involving the control of electric power or the quality of distribution systems.

Several operation programs are presently available the MAR-715L, which can be indistinctly selected when the instrument is turn on. Each program permits a periodical record in memory of some parameters, just continuously along the time or by predefined trigger conditions. All the setting process is done by means of intuitive menus shown on the instrument screen.

STANDARD OPERATION PROGRAM, ENERGY:
Basic program that permits to measure voltages, currents, powers and energies to save in memory the results over regularly recording periods  at user-defined time intervals of data files,  that contain average values, maximum and minimum values, etc. This files can be further managed in a PC by means of the VISUAL software.

When the MAR-715L is loaded with this program, the analyzer permits to effectuate detailed analysis on power factor correction, electric power consumption; and to obtain graphs of average, maximum and minimum values of 20 discrete basic electrical parameters.
