IV. Operating the Maxwell
IV.A. Navigation
The installed firmware will prompt you through initiation of a purification run. Follow the prompts
displayed on the LCD screen. Use the "Scroll Up" and "Scroll Down" buttons to move the cursor to the
desired prompt. Once the cursor is moved to the desired position in the list, press the "Run/Stop"
button to make the selection. At any time during the selection process, you may press the "Menu"
button to return to the beginning.
IV.B. Operational Qualification
With instrument power on:
Each time you turn the instrument on, it will automatically go through a self-diagnostic test during
which the platform, plunger bar and magnetic rod assembly are moved to check that the instrument is
properly calibrated. Upon completion of this self-diagnostic test, the screen will display either
"Diagnostic Check Successful" or "Calibration Error".
During instrument runs:
During instrument runs, the instrument will automatically do periodic self-diagnostic tests to verify that
the platform, plunger bar and magnetic rod assembly are within calibration during the purification
procedure. If the instrument detects that any of these parts are not within calibration during a run, the
method will pause and display "Calibration Error".
If calibration error occurs:
If a calibration error occurs, you will see the "Calibration Error" screen. Note the Error Code Number
displayed on the LCD screen and refer to the Troubleshooting section of this manual (Section VI) for
more information on each Error Code. If you are in the middle of a run, you can choose to continue the
purification procedure or abandon the run by turning off the instrument. Continuing the run will not
damage the Maxwell
