Window Symbols and Pop-ups
There are several different graphic symbols and pop- up windows that can
occur on the power meter display. These can occur for a variety of
reasons, for example:
• An error or warning occurs
• 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 a numeric value
There are three different colors used to signify the pop- up status:
• Green - used to allow data entry
• Orange - used to display information
• Red - used to display an error
Warning Symbol Pop-up
The warning symbol is displayed either in a pop- up window or directly in
the measurement 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, for example, to indicate that a
power sensor has insufficient bandwidth or a previous entered frequency
value in a table. Depending on the severity of the warning, the pop- up
may be displayed in Orange or Red.
