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 Confirm 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.
