P60013 BlkSz 16384
The Block Size parameter displays the size of the largest
contiguous block of memory available for use by the
database feature. This parameter will be seldom used.
However when either multiple databases of various sizes
are used or if rows are updated and/or deleted quite often,
the available memory can become quite fragmented.
If a situation arises where the total amount of available
memory, as indicated by P60011, is sufficient to create a
row and yet the "OutOF Memry" error message results,
then the maximum block size parameter can be checked
to determine if there is enough memory available in one
contiguous block to perform the operation.
If there is insufficient memory, the only remedy is to
compact the stored rows. This can only be accomplished
by downloading all of the stored database records and the
database setup to a computer and default the database
using parameter P65010. Then reload the setup and the
database records using the "Up-load" command.
P60014 dbase Error
The results of the last database operation can be checked
with this parameter. Each database operation sets a code
indicating the results of the operation. The
corresponding error message is displayed at this
parameter.
The next 16 database info modes display the number of
records (rows) created in databases which have been
setup. If a database has not been setup, then the
parameter for the number of rows within that database is
skipped.
P60021 dbas1 XXXX
through
P60036 dbas16 XXXX
Parameter P60021 will display the number of rows
currently stored within database 1, P60022 for database
2, etc... with P60036 indicating the current number of
rows stored in database 16. The last database info mode
allows the entire database setups to be cleared and
determines whether any of the database memory is
allocated to general use to allow large macro setups.
28.3 Identification Information
Parameters
P60100. 1993
This parameter provides the software copyright
statement.
P60101.0574 - 01007
This parameter provides the software revision code. This
should match the label on the EPROM at U13 inside the
instrument. Refer to this parameter along with P60102 to
determine the exact firmware version in your instrument.
P60102. YYMMDD
This parameter provides the date code of the software
release.
28.4 Audit Trail Parameter Information
AUDIT TRAIL
The 574 supports a recently accepted technique, called
the Audit Trail, to control the modification of calibration
and setup parameters. To prevent fraud in weighing, lead
seals have generally been used in the past to seal an
insturment by a Weights and Measures inspector after
having verified its operation and accuracy. The lead seal
is placed in such a manner as to prevent the removal of
an access plate which would need to be removed to
change the setup of the weighing device. However, with
the advent of weighing devices that are completely
controlled by software, it has become practical to require
the keying in of a special code in order to allow changes
to the setup parameters. The Audit Trail method is
becoming more accepted by Weights and Measures
officials as a way of controlling setup changes in
electronic scales. Basically, the Audit Trail provides a
count of the number of times that calibration or other
contolled parameters have been changed. Using this
method, the Weights and Measures inspector can verify
the operation and accuracy of the instrument and log the
Audit Trail counter by recording it in a log book or
writing it somewhere on the unit. The inspector can then
verify during future inspections that the Audit Trail
counter has not changed since the last approval. If the
counter was changed, this would be the equivalent of
finding a broken lead seal. In addition, for the indicator
to be considered an NIST approved, certain parameters
must be set to specific choices. If these parameters are
not set to the allowed choices, a warning message NOT
H-44! is displayed alternately with the Audit Trail value
for one second each.
TRADITIONAL SEALING METHOD
Some states and Canada have not yet accepted the Audit
Trail method. Therefore, the traditional method of
