Standard Operating Method: Stirrer Settings
Use Step 4 of the SOM Wizard (see Standard Operating Method: Stirrer Settings on page 4-10 ) or the
Stirrer tab of the Edit the SOM window (see
Editing SOM Settings
on page 4-23 ) to enter beaker size
and stirrer position.
You can also use the Stirrer window to disable stirrer buttons on the Analyzer Control Panel for the
duration of a run. If not disabled, these Control Panel buttons allow the operator to modify stirrer
speed or direction and turn the stirrer on or off (see page
1-5 ).
The Edit the SOM / Stirrer tab includes an additional feature that allows the operator to copy
manual settings into the SOM (see
Copying Manual Stirrer Settings
on page 4-11 ).
NOTE
The Multisizer 4 will automatically position the stirrer based on the beaker size you select in the
SOM. Beckman Coulter recommends that you use Multisizer 4 Smart Technology Beakers with
automatic stirrer positioning to ensure consistency and accuracy of results.
To use the SOM/Stirrer Settings window:
1. In the Sample Beaker pane, select Accuvette® ST or the beaker size you will be using. To enter
the beaker size automatically, hold the bar code in front of the Bar Code Reader on the Analyzer
Control Panel. For more information on the Bar Code Reader, see page
1-7 .
In the Other field, enter a description (maximum length: 40 characters) for a non-standard
beaker size.
2. In the Stirrer Position pane:
• Select Automatic to automatically position the stirrer inside the beaker or Accuvette® ST.
For consistency and accuracy of results, Beckman Coulter recommends that you use Smart
Technology Beakers with automatic stirrer positioning.
You can turn the stirrer off by pressing the stirrer ON/OFF button on the Analyzer Control
Panel or by selecting
Run > Stirrer Off
on the Main Menu bar.
