rate is not critical, as in static weighing, set FILTER= to:
If the sample

FILT ER=1 (FMAX=6, FBRK=12, SAMPLES=2/Sec) or

Critical Sample Rate
With a critical sample rate, as in a filling operation, use Custom Filtering (FILTER=3).
1. SAMPLES= S
Set the sample rate as close as possible to produce a display graduation change for
every graduation of material added to the scale.
