The following data are indicated:

Type:

Type of measurement set:

Fix: The instrument has detected and saved an event when the current's

RMS value, calculated in each half-period, exceeded the value of the

threshold defined by the user.

Var: The instrument has detected and saved an event each time the

current's RMS value, calculated in each half-period, exceeded the

previous RMS value (i.e. the RMS value calculated in the previous

half-period) by a quantity equal to the threshold defined by the user.

Limit:

Set current threshold.

Duration:

Set observation interval.

This page also shows the total number of inrush currents occurred (Number of Inrush
Currents
).

The following keys are active on this page:

 The

F3 and F4 keys (or the MOD(+) and MOD(-) items on the display) enable

the user to filter the inrush currents to be selected. It is possible to select All,
Phase1, Phase2, Phase3, Neutral.

 The ENTER key (or the smart icon on the display) confirms the selection

previously made and displays the table of inrush currents.

 The ESC key (or the smart icon ) to exit the function and go back to the

“Inrush currents” page (Fig. 135).


This page shows the graph, the cursor position, the maximum/minimum current and
voltage values, the current and voltage value relative to the cursor position of the selected
inrush current.

Fig. 137: Inrush current graph


The following keys are active on this page:

 The

F1 key (or the SEL V,I item on the dislay) shows the voltage and current

graph.

 The

F2 key (or the SEL V item on the dislay) shows the voltage graph.

 The

F3 key (or the SEL I item on the dislay) shows the current graph.

 The right and left arrow keys move the cursor to the right or to the left along the

graph.

 The

ESC key (or the smart icon on the display) to exit the function and go back

to the “Inrush currents” page (Fig. 135).
