Place the 99% standard in the sample drawer as
shown. Note the position, so that it can be rotated
as directed.
The standards should have 4 scribed lines to help
set the rotational position.
Gently place the probe into the middle position
when prompted by Vision.
Close the drawer first, then gently lower the Smart
Probe, into light contact with the standard window.
Vision requests rotations for replicates.
Lift the Smart Probe slightly, then rotate the
standard 90 degrees each time, and continue.
Select the requested standard from the set.
Labels on the back identify each standard.
Note the mini-CD that contains the
“Standards File”. This file is used during IPV
Setup, but not during Photometric Test.
Photometric Test uses the file that is created
during IPV Setup. The newly-created file is
stored in the Vision directory.
7.2 Evaluation Diagnostics
Evaluation Diagnostics are used to verify that the instrument is operating within allowable
parameters. These tests should be run approximately once per week.
This information is meant to guide the user through the tests in an expeditious manner. A more
complete description of these tests is given in the Vision Manual, in the Diagnostics section. A
discussion of the theory and interpretation of results is provided in the Vision manual.
