Operating Basics: User Interface

If the first character of the time specification is a plus (+) or minus (–)sign, the time is taken relative to the current cursor position.

When the Time Axis display is set to Time of Day, times are taken as time-of-day; day specifications are relative to 0, the first day of the test. Thus, 1:00 PM on the day following the start of the test would be entered as 1d 13:00:00.

The Live Update check box causes the data display to track new data as a test is running. When it is set, the cursor is automatically positioned on the most recently acquired sample and the windows scroll accordingly. Moving the cursor automatically turns off this feature.

When the Zoom Out/In slider is set to a resolution other than the finest, the display may be automatically zoomed by clicking the mouse at one edge of the area of interest, holding down the left button, and dragging it to the other edge. The zoom setting and scroll position will adjust to show the selected area at the highest resolution possible.

The Test window shows the test start time and date, elapsed time, and test state.

The Data at Cursor window shows the cursor position (elapsed time or time-of-day, as selected), the count of the selected parameter at the cursor, and the maximum value for that parameter at the current display resolution.

The Search controls allow searching, forward or backward, for an occurrence of the specified parameter. The search starts from the cursor location; it will not wrap beyond the end (forward) or beginning (backward) of the data. For the B1, B2, FAS, MS-REI (REI-L), B3, REI-P, and TSE parameters, one may specify a search threshold: the search will find only intervals containing at least that many errors.
