Definition:

1201 uses an averaging digital filter to yield a reading for display from a

specified number of measurement readings in the past. The past

may be in the range of 2 to 100. User may select one of the two modes

of digital filter operations: Moving Average and Repeating Average.

The moving average filter puts the specified number of reading
