Below the toolbar Averager button (and its thin dialog pop-up button) is a "sunken" readout that shows the total frames acquired by the current waveform or spectrum average.

In Linear, Waveform Histogram, Waveform PSTH, or Spectrum Peak modes this counts up to the relevant waveform or spectrum Frames Request and stops; the display enters Pause mode to signify the average is done.

Activating Avg Add and Avg Sub when an average is done will cause the counter to continue to count up until another Frames Request amount of frames has been added. (Note that for Avg Sub the data values are subtracted, but the counter still records the total number of frames... it never counts down.)

In Exponential modes, the Frames Request acts as a time constant for the average. The counter stops increasing when it reaches this value, and 'TC' is appended to the count to indicate the time constant has been reached. The exponential average continues to run until explicitly toggled off.

In Spectrum Peak mode, if you set the Frames Request to 1 it signifies continuous peak hold. In this case the counter rises until it reaches 2147483647, after which it will change to 'Cont Peak'. Peak operation will continue until you hit Pause, or toggle Average off to abandon the peak display.

If you are averaging file data and an average completes and enters Pause mode, unPausing will abandon the average and cause the file to continue to scroll from that point. Alternatively, any manual file motion key will also cause the average to be abandoned. If you just use the unshifted <> keys you can abandon the average and see the last waveform or spectrum that was included in the average.
