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.
Wait Symbol
The wait symbol is displayed when the power meter is carrying 
out a procedure but no action is required from you. The symbol 
may appear directly in the measurement window or in a pop up 
window. It may appear, for example, during, zeroing or 
calibration.
