Installing an Aperture Tube
This section describes how to correctly place an aperture tube in the Analyzer. After installing the
aperture tube, you will need to:
• Calibrate the aperture
• Follow the step-by-step guide provided in the Change Aperture Tube Wizard. The Change
Aperture Tube Wizard allows you to verify calibration, test aperture settings, and enter the new
aperture tube size and serial number in the Multisizer 4 software.
To install an aperture tube:
1. Clean the new ST Aperture Tube. For instructions on the proper aperture cleaning procedure,
see Cleaning the Aperture Tube, Beakers, and Accuvette® STs, page 1-15.
