3.2 Setting of Measurement Function and Interface
Display
The power meter has three interface display styles for measurement of basic
parameters. At most five pages are displayed in each style. When one or more
important measurement parameter(s) should be highlighted, the View1 or
View4 mode can be freely enabled to design the humane display style. When
you need to view all parameters at the same time in one interface, the View12
mode can be enabled.
Take power measurement as an example. The interface can display four
parameters in the large font form: effective voltage, effective current, active
power and power factor. Operating procedures are as below:
Operation steps
1. In the “Meter” interface when the soft key corresponding to “VIEW 4” is
pressed, 10 measurement parameters can be displayed in total, 4 of which
are displayed in an amplified manner. Other measurement parameters can
be viewed by pressing
key to turn pages, as shown in the figure
below.
2. When the soft key corresponding to “CONFIG” is pressed, the
measurement function can be selected and the interface display
