Set Average Time

The average time is a multiple of the period of the voltage of current source. The settings
are automatically adjusted during measuring. For example: the average time is set to 19
ms; at a frequency of 50 Hz, it is automatically adjusted to 1 period, that is, 20 ms.
Short average times are useful, if you wish to analyze individual periods,
measuring even minute interferences. With long average times, for example
300 ms at 50 Hz, short-term interferences are not shown.
Value in column Tavg[s] is highlighted.
