Window Symbols
There are a number of different graphic symbols and pop- up windows that can
occur on the power meter display. These can occur for a variety of reasons
such as when:
• an error or warning occurs.
• a confirmation is required.
• you are required to wait while the power meter carries out a procedure.
• you are required to select an entry from a list.
• you are required to enter an alphanumeric value.
Warning Symbol
The warning symbol is displayed either directly in the
measurement window or in a pop- up window when such an
event occurs. A pop- up window is displayed for
approximately two seconds. The text in the pop- up window
gives details of the warning type. This symbol may also
appear on a measurement window, for example, to indicate
that a power sensor is not connected.
Confirmation Window
This pop- up window is displayed when
you are required to press
to
verify your previous selection. For
example, prior to a preset being carried
out.
