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).
