The StirbBar screen is used to adjust the speed of the stir bar. The stir bar has two operating speeds: stir speed, where
the stir bar rotates smoothly in the sample module and jump speed, where the stir bar jumps to help clear air bubbles from
the module during the flush cycle.
Note: The sample module must be full of buffer when adjusting stir speed. To fill the module with buffer, see 7.2.3
Modules.
Touch the [Stir] button under Stirbar1. Verify the stir bar is rotating smoothly, but not jumping.
If the stir bar is jumping, use the Down Arrow Button to decrease the stir speed until the stir bar is spinning smoothly.
Touch the [Jump] button. The speed should increase to Jump speed and the stir bar should jump.
If necessary, increase the jump speed until the stir bar is jumping. If the stir bar won’t jump, even with the speed set to
maximum (100), replace it.
Touch the [Spin] button. Verify the stir bar is spinning smoothly and not jumping. If necessary, reduce the stir speed until
the stir bar is not jumping.
Touch the [Off] button under the same stir bar to stop the stir bar.
For the 2950, repeat this process for the remaining modules (Stirbar2 and Stirbar3).
After you have adjusted the stir speed for all modules, touch the [X] button to return to the Main display.
