Analyzer Checklist
Beckman Coulter recommends that you follow this checklist before each sample run, even if no
change in Analyzer settings is required. For information on preparing for a sample run, see
Preparing the Analyzer for Sample Runs , page 1-18 .
Before starting a sample run:
1. Power on the Analyzer, open the Multisizer 4 software, and connect to the Analyzer (see
Opening the Multisizer 4 Software , page 2-1 ).
2. Fill the system with electrolyte solution.
3. Secure the correct aperture tube in place (see Installing an Aperture Tube , page 3-2 ).
4. Empty the Waste Tank, if necessary.
5. Place a Multisizer 4 Smart Technology Beaker or Accuvette® ST with clean electrolyte and
sample on the platform.
6. Raise the platform and make sure that the aperture is immersed in the electrolyte.
7. Close the Sample Compartment door.
