4.2 Preparing the Measurement
4.2.1. Using the Multi Sample Tray
Fill the appropriate volume of samples into Cedex Sample Cups (maximum 20) and place them on the Multi
Sample Tray according to the desired sequence. Gently insert the tray into the notch until the automatic tray
rope starts pulling it in.

As a safety precaution, leave all of the empty Cedex Sample Cups in the Sample Tray after the measurements
have been completed.
4.2.2. Ejecting the Multi Sample Tray
The Multi Sample Tray can be ejected by gently pushing on the tray only when the system is idle. The tray
cannot be ejected if the system is moving or the needle is down in a cup.
If a problem occurs with the system when the needle is down (see, for example, “Disruption of Measurements”),
restart the Hardware Management to render the tray ejectable again (see “Carrying out an LM Shutdown
and HW Shutdown”). In some cases it may be necessary to restart the Cedex HiRes Software 2.2 and Analyzer.
