5.4.6. General

Parameters


This option permits the selection of network parameters for recording operation. This level
included several sub-level for a detailed selection depending on the type of system on test
(see § 5.3.1).
Depending on the selection performed, different error screen can be shown by meter. The
below situations are possible:

Fig. 88 shows the situation which the error due to no parameters selection is performed
also if the “General Parameters” is selected at display. Please note the text on grey
background and the not selected check box. In this situation other type of analysis as
Harmonics, Voltage Anomalies, etc.. are not possible. Pressing F3 key (or touch “SEL” at
display) to exit from this error condition. In this order the flag of “General Parameters”
check box it will be selected and the below screen (with black text background) is shown:

In example of the above picture 96 parameters are been selected on total of maximum 251
available and the correspondent autonomy is shown automatically by meter in this case.

CAUTION

The “General Parameters” check box activated flag, automatically select the
main electrical parameters whose number depends on the selected system
(Voltages, Currents, Frequency, Power Factor, Active, Reactive, Apparent
Powers, Active, Reactive, Apparent Energies). The failure to select “General
Parameters” flag automatically doe not select the above parameters.
