provide an ongoing record of performance.
The test uses the same standards used in IPV Setup. Photometric Test compares current spectra of
each standard to those stored during IPV setup. If any differences exceed normal tolerance values,
the instrument can be assumed to have changed in some manner, and may need service.
Because the calibrated photometric standards are the link to previous photometric performance, the
standards should always be stored in their wooden box, and protected from fingerprints, dropping,
or other damage. If any cup is opened, dropped, or otherwise altered, Photometric Test results may
fail.
To run Photometric Test, select it from the
Diagnostics menu.
Vision requests a “Standard File”. For
Photometric Test, use the RSSVxxxx.da file
stored in the Vision directory. This file was
created during IPV Setup. Current
photometric readings will be compared to
that initial file.
Click on the RSSVxxxx.da file as shown.
(The serial number will be different, of
course.) Click “Open”.
Do not use the file on the standards mini-
CD for Photometric Test, as it will cause
Vision to return an error message.
Vision requests a tolerance file. The
tolerance file was loaded in the C:\Vision
directory, and is an “XDA” formatted file.
Select this file and click “Open”.
