for particular process conditions, go through the manual Tuning/

•
TIME BASE (Sec) - The time base is the length of time in seconds
between two weight readings that are subtracted to determine the
flow rate.
•
DERIVED LOSS OF WEIGHT SLOPE (Interpreted as GAIN-IN-
WEIGHT) graph. (See Fig. 6-7)
•
This graph shows the “worst-case” slope derived from
weight readings taken at the beginning and end of the
Timebase Period. The first reading was taken at a low
spike while the second reading was taken on a high spike.
As a result, the HI 2160RC
PLUS
interprets this information
as “GAIN-IN-WEIGHT” data instead of ‘LOSS-IN-
WEIGHT” data. On the Action display an
↔
graphic
appears. (See Fig. 6-6) The arrow appears only when try-
ing to run the feeder at low feed rates, where the weight
variations exceed the amount of weight lost within the
TIMEBASE period.
