Applied Biosystems 7500 Maintenance and Calibration When to Calibrate the ABI 7500 When you install the system. You must perform all calibrations in the following order: ROI, Background, Optical, Dye, instrument verification. Every 6 months, or as often as necessary, depending on instrument use. After replacing the lamp. IMPORTANT! After every ROI calibration, you must perform a background calibration, optical calibration, dye calibration, and instrument verification. Maintenance Menu Region of Interest Calibration The ROI calibration maps the positions of the wells on the sample block so that the software can associate increases in fluorescence during a run with specific wells of the plate. Because the instrument uses a set of optic filters to distinguish the fluorescence emissions gathered during runs, you must generate a calibration image for each individual filter to account for minor differences in the optical path. 1 Troubleshooting Condition: The ROI image is faint or you cannot generate a successful calibration. The sample block may be in its lowered position. If the CCD Control Settings in the ROI Inspector displays Block Up, click Block Up to raise the sample block. Check that the heated cover assembly is pulled all the way forward to ensure that the tray can be pushed in properly Background Calibration Background Calibration If the instrument did not complete the background calibration run: Repeat the calibration. If the problem persists, contact Applied Biosystems. If the background calibration failed: One or more wells of the background plate produced spectra that exceed the maximum limit for background spectra on the Applied Biosystems 7500/7500 Fast Real-Time PCR System. Repeat the calibration using the same background plate. If the calibration fails again, repeat the calibration using a different background plate. If the calibration fails again, determine the source of the contamination. 2 Optical Calibration Optical Calibration As per ROI calibration. Same plates and handling conditions. Compensates for the extra deep red filter found in 7500 series. Spectral Calibration Spectral Calibration Spectral Calibration Spectral Calibration 3 Lamp Status Lamp status The Lamp Status/Replacement dialog box displays: Condition – Indicates one of the following conditions: Good – The lamp is functioning well and does not need to be replaced. Click Close. Failed – The lamp bulb must be replaced. Click Close, then replace the lamp. Change Soon – The lamp usage is above 2000 hrs; Applied Biosystems recommends that you replace it. Click Close, then decide whether or not to replace the lamp. Usage (Hours) – The total number of hours that the lamp has been illuminated. Lamp Current – The output current of the lamp in amperes (A). Low current can indicate a potential future failure of the lamp. Date Last Replaced – The date of the last lamp replacement.
