Figure 2-1. Measurements with TAveragc < 1 second
For averaging times of more than 1 second, the x value is given by the formula
= XM (l - + Sample. (T^)
\ / \ -^avg )
Where
Xnew is the new, displayed result,
Xoid is the previously displayed result,
Sample is the value read by the hardware,
Tavg is the averaging time (as set by the user), and
Tsampie IS the time taken, by the hardware, to make a reading.
If the measurement conditions are changed (for example, by a range change in
autoranging) Xoid is reset, and the averaging starts again. This is why the display
update seems faster in autoranging.
