QA-Calibrate uses Microsoft's Setup program, which will
not function properly if your Autoexec. bat file does not include the
line:
SET TEMP=C:\DOS
Note that the backslash is recommended.
When installing QA-Calibrate to a protected network, follow
these guidelines:
- Users must have Read / Write access to: CALIB.MDB,
CALIB.LDB, CALIBA.MDB and CAILIBA.LDB.
- When using the Repair/Compact utility, a temporty file
is created in QA-Calibrate's directory and then deleted. Users that
run this utility must also have create and erase access to this directory.
The printer should be using the same font as shown on
screen (Times New Roman, a True Type font).
If the printer is printing different from that, or that is illegible,
then it is most likely due to either a printer substitution table or a
printer driver that is scaling poorly.
When a Calibration is performed, the measurement readings
that are taken are the "results" of the calibration. These results
are compared to the measurment standard's last calibrated value and the
acceptance criteria. If the readings do not fall within these acceptance
criteria, the gage has FAILED its Calibration. As a result of failing
the Calibration, several actions may be taken, including maintenance or
adjustment of the gage. A subsequent Calibration must then be performed
and documented to return the gage to service.
This methodology allows you to easily see that the instrument was out
of calibration when found. The Calibration History can be reviewed to
see how often this occurs, which would be a condition suggesting more
frequent calibration.
