9.2.9 FIL TI (Filter Time Constant)

Filter time constant is used to determine the number of readings the meter
will average before displaying an input value. The choices are 001, 002,
004, 008, 016, 032, 064, or 128.
For fixed filtering, the averaged number of samples is fixed; for Automatic
Bandwidth Control, the chosen value is the maximum number of samples in
the average computed by ABC when the input is not changing significantly
(ABC, for slowly-moving signals, filters by averaging the "TI" number of
samples, but follows signal changes rapidly by decreasing that averaging
number).
Pressing the 'MENU' button stores your selection and moves on to "RESET
1" and then to "RUN" (unless setpoints, outputs, or communications have
been unlocked for programming change)
