Non-Critical Sample Rate
If the sample rate is not critical, as in static weighing, set (+.6'4 to:
y (+.6'4 (NO Filtering)
y (+.6'4 ((/#:, ($4-, 5#/2.'5/Sec) or
y (+.6'4 ((/#:, ($4-, 5#/2.'5/Sec).
Critical Sample Rate
With a critical sample rate, as in a filling operation, use Custom Filtering ((+.6'4).
1. 5#/2.'5 SAMPLE RATE (1 to 200 samples/second) determination:
Set the sample rate as close as possible to produce a display graduation change for
every graduation of material added to the scale.
Material Flow Rate (lbs/second)
Interval
= 5#/2.'5
100lbs/sec EXAMPLE:
10lbs
= 10s/s = 5#/2.'5
2. ($4- FILTER BREAK RANGE (1 to 64 graduations) determination:
Turn the filtering off by setting (+.6'4. Operate the system as it will be normally
used and, by observation, determine the number of grads of instability that needs to be
filtered out. Set the break range (($4-) to that value.
Weight Change
Interval

EXAMPLE: 20,000 x 10lb capacity scale with 800lb variation in the weight display.

= ($4-
3. (/#: MAXIMUM FILTER LEVEL (0 to 255) determination: Set to desired results.
4. If stability is unacceptable with any setting of (/#:, reduce the sample rate and/or
increase the break range, ($4- setting for increased filtering.
