zero_span
The zero_span table contains data from the automated zero/span sequences.
Records are written to this table when the calibration sequence is run (either
automatically initiated based on time, or manually initiated). Each zero/span
sequence will put multiple records in the zero_span table, corresponding to the
steps in the sequence. The actual number of records will depend on which
options are chosen. If a step is skipped, no record will be written to table for
that step. See Section 6.2, Automatic Zero and Span, for details.
The records in the zero_span table are distinguished by the first two values:
Sequence_Step (1 to 11) and V alveNumber (0 if no valve is selected, or 1 to
6). Space is allocated on the card for 33,000 records (approximately 200 days
