Automating Measurements
Statistical
Process
Control
lf
you collect data on your production process, you can use statistics to
control and improve your process. lbols such as histograms, Pareto diagrams,
and scatter plots can help you to quantify your process’s behavior, and
identify trends, cycles, and other “unnatural” patterns.
You can purchase computer programs such as SAS and
SPlus
to perform
statistical analyses. HP VEE, which you can use to control your analyzer, also
offers some statistical capability. You can also use add-in macros for popular
spreadsheet programs.
Transferring
Files
Two example programs
(“GETFILE”
and “PUTFILE”) demonstrate how to
transfer
liles
from the analyzer’s mass memory to and from mass memory of
an external controller via
HP-B
Instrument states and program files may
be transferred to or from the analyzer’s internal non-volatile memory,
MEM,
internal-volatile memory,
RAM,
and the internal 3.5” floppy disk, INT. This
can be a convenient method to archive data and programs to a central large
mass storage hard drive.
These example programs are found on the Exumple Programs Disk that was
shipped with your analyzer, and are described and listed in the Programmer’s
Guide. ‘lb run these programs, connect an external controller to the analyzer
with an
HP-lB
cable.
