The
i
Series instruments include a built-in datalogging capability as a
standard feature. The operator is allowed to create two different types of
records, which for historical reasons, are named lrecs and srecs. Each record
can contain up to 32 different fields, or data items, and records can be
created at user-defined intervals ranging from 1 to 60 minutes.
Record generation is tied to the instrument’s real-time clock. For example,
if the logging period for srecs is set to 30 minutes, a new srec will be
generated on every hour and every half hour (10:00, 10:30, 11:00 …).
Lrecs and srecs function independent of each other. So, for example, an
srec containing just the current HCl level could be generated every 5
minutes while an lrec containing a full set of diagnostic data could be
generated once every hour.
The analyzer's computer system includes three megabytes of flash memory
which is enough to store a full lrec containing 32 data items and a full srec
containing 32 items once each minute for a week (>20,000 total records).
If logging is limited to the minimum content of date, time, HCl
concentration and error flags, the analyzer can store data once each minute
for 4 months (>190,000 total records).
The Datalogging Settings menu allows the user flexibility in how data is
stored and recorded.
