under Configure, Options. That is, if the IPV Setup file is acquired with Reference Standardization
switched on, and with Window Correction switched off, then Photometric Test should be performed
using the same settings. The System Manager should pay particular attention to this. If options are
not consistently applied, there will be a bias in the results of Photometric Test. The bias may be
enough to cause test failure, depending upon selections.
Because the XDS MasterLab is a sensitive instrument, it can detect differences in temperature of the
standards, and results may be affected slightly. To minimize this effect, be sure the standards are at a
stable temperature before use. If lab temperatures vary, the user may place the standards inside the
RCA cover for some time to let them equilibrate to a stable temperature.
IPV Setup is run as follows:
Select IPV Setup from the Diagnostics menu.
Vision requests a “Standard File”. This is provided
on a mini-CD, packed in the wooden box with the
standards.
Insert this mini-CD into the CD drive, select that
drive in the dialog box, and click on the
TSS4xxxx.da file as shown. (The serial number will
be different, of course.) Click “Open”.
(The standard file is “Standard File” format, which
is used where it aids in file transfer.)
The Standards file was selected from the E: drive. It
may also be copied into the C:\Vision directory for
regular use.
For Number of Replicates, the default setting is 1 for this
instrument.
Click on “OK”.
Vision will begin to take an instrument reference scan.
The red progress bar at the bottom of the Vision screen
indicates status.
