4.2 The kind of display
4.2.1 Measurement display
A measurement value display has the two following types of displays.
The change of the measurement display element of the main monitor by switch operation and the change of the
phase / line display of voltage is possible (temporarily).
In an instantaneous 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.
① Measurement display
Measurement factors, such as 3-phase voltage, zero-phase voltage, and frequency, are displayed.
The measurement value of four factors is displayed at the maximum.
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 no operation.
