assigned a LABADMIN role.

Pooling Manager Trace Messages

The Hamilton Microlab STAR IVD / STARlet IVD Pipettor communicates

with the Roche PDM software to log every action that is carried out

during the pipetting process. These log messages can be viewed by the

laboratory administrator and used to help troubleshoot pipetting errors

1 Click the Pooling button in the global command button area in

pipetting channels.

The Trace Results dialog box also displays the reason for the error.

The type of information that is displayed depends on the pipetting

step.
