The analyzer has a 9 buttons keyboard to perform configuration and

control actions of all the instrument options.

- [ON] to turn the analyzer on.

- [OFF] (Quick press) to turn on/off the display back-light.

- [OFF] (5 seconds press) to turn analyzer off.

- [6666], [5555], [4444] & [3333]. To select among several options.

- [SET] to access setting options.

- [ENTER] to validate a setting option or to program some parameters of the visualization screens.

- [ESC] to select different visualization screens or to exit the setting actions.

specifications, the protection of the instrument can be damaged. Note that with

the instrument powered on, cover opening or elements removal actions may allow accessing dangerous parts. Therefore, before any adjustment, replacement, maintenance or repairing operation is carried out, the instrument must be disconnected from any power supply source.

When any protection failure is suspected to exist, the instrument must be

immediately put out of service. Contact then with a qualified service representative.

scale to obtain a better accuracy.

To start measurement works with the analyzer:

11) Connect to the main with the factory-shipped cables. Also connect the protection earth terminal to avoid possible disturbances over the analyzer.

12) Connect the voltage leads at each phase of the monitored system, as well as the neutral when it exists.

13) Connect the Current clamps at each phase conductor. Each current phase must coincide with its voltage phase.

14) Respect the connection modes shown at each diagram to correctly achieve powers, PF and energies readouts.
