Use Instrument Calibration (XDS only)

This is a method to adjust the instrument wavelength profile to an external, traceable wavelength
standard. It is checked as a default for XDS. Required for Calibration Transfer.

Use Window Correction (XDS only)

This is only used with specific XDS process Instruments. Do not select this option.

When calibration or library transfer (between instruments) is anticipated, be sure that Blank
Correction and Instrument Calibration are selected. These features assure best method
transfer between similar instruments.

Some of these selections are spectroscopic
calibrations, and are used to apply corrections to
the instrument to minimize differences between
units of the same configuration.

The correction programs are accessed from the
Diagnostics menu bar, shown at right. The
diagnostic steps are explained in the sections that
follow.

7.1.1

Instrument Identification

When Vision first communicates
with the instrument (or after
disconnection and re-connection)
this screen is shown.

Vision must establish the
configuration and have it verified
by the user. This assures that test
data is sent to the correct location
in the Diagnostic Database.

The monochromator Instrument
Serial Number and the Sample
Module Serial Number are read
from stored information inside the
instrument.

Click “OK” to accept the instrument
identification.
