D4 Tools allows you to see what is causing an error in the D4 instrument and remediate it. In D4 Tools, click "Online Status", then click the icon on the left (Figure ##A), this connects the D4 Tools software with the D4 instrument and completes a diagnostics (identifies any errors). The initial screen (Figure ##) shows the instrument status. Any red squares indicates an error. You can investigate the error by clicking on the square. Only trained techs should be trouble shooting errors (errors other than drive initialization) on the D4. To initialize the drive(s) that did not initialize with the commander software click the '+' positioning drives, then click the drive that did not initialize (Figure ##B). Click the Adjust button (Figure ##A). Please note that when you initialize the drives you can hear the drives moving inside the D4. If you hear a clank or bang and the instrument stops working you will have to get a trained tech (trained in D4 trouble shooting). There is a in-depth sample changer procedure to correct for misalignment in the Bruker Manual (cupboard in XRD lab) but it should only be preformed by trained techs. Alternatively, you can contact Bruker and they can advise or remote into the D4 to fix any errors. Note that some errors can be fixed by clicking the Red Cross icon (Figure ##C). The program can identify and fix some errors. Try that icon before contacting Bruker.
