DESCRIPTION OF THE INSTRUMENT

Active virtual alarms warners.

Current energy drain indicator (kWh) by means of flashing, proportional to the measured energy (the

higher the flashing frequency, the higher the energy drained. Max. frequency 16Hz pursuant to stan-
dard EN5047-1).

The keyboard is divided into two areas, the top area is dedicated to the measurements with direct access
to specific visualization screens.

Visualization of the counters screens: each pressure of the button corresponds to the visualization of

a screen with counters related to different energies (see the table with the measurement screens
below).

Visualization of the current voltage and frequency (see the table with the measurement screens below).

Visualization of the instant cosf and powers (see the table with the measurement screens below).

Visualization of the harmonics (see the table with the measurement screens below).

The keyboard in the bottom area is especially dedicated to instrument programming.

Exits the submenus, exits programming.

“Up” button, enables to browse the menus and to increase the values to be set.
