4.2 The kind of display
4.2.1 Measurement display
The change of the measurement display element of the main monitor by switch operation and the change of
the phase / line display of current / voltage is possible (temporarily).
In a general measurement display, if switch operation is not performed for 10 minutes after changing a
display element, it returns to the original measurement display element automatically.
Measurement factors, such as current, voltage,
and active power, are displayed.
The measurement value of four factors is
displayed.
Setting which always displays a measurement
factor is possible. And, it is possible to
change to a display of the maximum value and the
minimum value, about the measurement factor
which performs holding of the maximum value and
the minimum value by switch operation.
These maximum values and the minimum value are
reset by switch operation (it updates to the
instantaneous value at the time).
In addition, as for the maximum value and the
minimum value, power-supply reset is not
cleared either. And, this display is held by
even after 10 minutes of switch non-operation.
