Congratulations. You have completed the Daily Setup with CHK course for the Dimension® EXL™ 200 integrated chemistry system. Listed below are the key points that have been presented. Take time to review the material before you proceed to the final quiz. Once you have reviewed the content on this page, you may proceed to the assessment portion of the course. Clean the sample area and empty cuvette waste: Press Pause to stop the sampler system from moving while cleaning the sample area. Remove all segments and clean inside the sample area with a damp cloth. When emptying cuvette waste, cut between the cuvettes at least 12 inches away from the instrument to prevent spilling of contents and prevent cuvette jams. If barcode readers need to be cleaned, use a cloth lightly moistened with water. Check for other maintenance requirements on Daily Maintenance Routines screen: If maintenance tasks are required, the Daily Maintenance Routine screen will display function keys to open applicable System Counters screens. On this screen, you also can view the last time a component was cleaned or replaced. Items that require maintenance will be displayed in red. Run a System Check: A CHK Flex® reagent cartridge must be loaded onboard the instrument to perform a System Check The Photometric Sampler, Reagent probes (R1 and R2), and HM system use the CHK solution from the onboard Flex® reagent cartridge. While viewing the Daily Maintenance Routines screen, press the Help key to find System Check specifications. Update Maintenance Log: Use the Daily Maintenance Log to record temperatures for the Cuvette, Reagent, HM, and confirm other tasks (empty cuvette waste and run System Check) have been completed. Use the Daily System Check Log to record Photometer wavelengths are OK, Mean & SD for R1, R2, Sampler, and HM, maximum LOCI® module reading and CHK lot number. Select Next to continue. Use the Daily Maintenance Routines screen to run routine tasks that are to be performed at least once every 24 hours. Performing these maintenance tasks daily will help keep the instrument running efficiently. Clean Sample Area Keep the sample area clean to prevent biohazards and chemicals from accumulating in the sample wheel and segments. Clean the sample processing area with a cloth lightly moistened with water. Do not spray into the sample area. If the barcode reader needs to be cleaned, use a damp cloth. Empty Cuvette Waste Empty cuvette waste at least once every 24 hours, but more often for high-volume use. Cut between the cuvettes to prevent spilling of cuvette contents. Cut the film strip at least 12 inches away from the instrument to prevent cuvette jams. Tip: Before cleaning the sample area, press Pause to stop the sampler system from moving. Select Next to continue. The Dimension® EXL™ 200 integrated chemistry system tracks when maintenance tasks are due. Screens display usage cycles and the last time the component was cleaned or replaced. Items that require maintenance will be displayed in red. To access the Daily Maintenance Routines screen, select: F4: SYSTEM PREP F8: DAILY MAINT. If maintenance is required, a function key will direct you to the appropriate screen: F2: CHECK COUNTS F3: CHK HM COUNTS Tip:Perform Other Maintenance tasks before running the System Check. Follow the appropriate Other Maintenance procedures in the Operator’s Guide. Daily Maintenance Screen Learn about the Daily Maintenance Routines screen. Checklist TitleChecklist TypeChecklist ContentDaily Maintenance Routines ScreenHTML Select each checkbox to learn more about the Daily Maintenance Routines Screen. Temperature CheckHTML Temperature check will display temperatures that will be recorded on Maintenance Log. You also will see these temperatures on the System Check printout. Pump PrimeHTML Pump prime indicates the number of prime cycles the instrument will perform before running the System Check. System CheckHTML System Check line details how many cuvettes remain on the cuvette film cartridge and how many cuvettes have failed the photometric QC check. Empty Cuvette WasteHTML Empty Cuvette Waste is always displayed in red as a constant reminder. CHK LotHTML The instrument stores 2 lots of CHK in memory. CHK Carton ValuesHTML Enter the lot specific CHK carton value which is located on the carton end flap. Other MaintenanceHTML Other Maintenance is required as indicated by F2 and F3 function keys and information in the message area. When complete, select the X in the upper-right corner to close the window and continue. The System Check verifies the accuracy and precision of the Dimension® EXL™ 200 system. Running a System Check once every 24 hours ensures proper operation of the following instrument components: Photometer system, R1, R2, Sampler, HM wash, and LOCI® module. You may be required to run a System Check as follow-up to some maintenance tasks. A System Check also can be useful when troubleshooting chemistry or hardware issues. The System Check can be programmed to run automatically at a convenient user-defined time of day. The System Check does not check the IMT module. For additional information, refer to the Dimension® EXL™ 200 IMT Technology Online Training course. Programming Automatic System Check Learn how to program a System Check to process automatically. From the DAILY MAINTENANCE ROUTINES screen, select F8: AUTO SETUP to access the DAILY MAINTENANCE AUTO RUN SETUP screen. Choose your customized run time using a 24-hour format. Always remember to select F1: SAVE CHANGES to store your preferences. When complete, select the X in the upper-right corner to close the window and continue. Running a System Check Learn tips about Running a System Check. A CHK Flex® reagent cartridge must be loaded onboard the instrument to perform a System Check. The sample probe, reagent probes (R1, and R2), and HM system use CHK from the onboard Flex® reagent cartridge. The CHK Flex® cartridge carton value for each lot is located on the outside of the reagent carton. You must enter this value into the Daily Maintenance Routines screen. The instrument will alert you if a CHK Flex® reagent cartridge is not onboard the instrument. When complete, select the X in the upper-right corner to close the window and continue. The System Check printout displays the System Check results. Be sure to record all System Check results onto the Maintenance log. Tip: If the System Check fails, rerun the System Check to confirm that a problem exists. Refer to the Troubleshooting section of the Operator’s Guide to assist troubleshooting the problem.

If any component did not pass specifications, the failed component will be highlighted. Photometer Wavelength: The Dimension® EXL™ 200 system checks absorbance readings for the 10 different photometer filters. Photometer Maximum: No CHK solution is used here. The photometer takes two readings of a blank cuvette and calculates the difference between the readings. The system performs this 5 times and prints the maximum difference. Reagent #1: System Check results for R1. Reagent #2: System Check results for R2. Sampler: System Check results for the photometric sampler. HM Wash: System Check results for HM wash 1 and 2 for systems that include an HM module. Sample Probe Cleaner: Checks for the presence of sample probe cleaner in the sample probe drain. Reagent Probe Cleaner: Checks for the presence of reagent probe cleaner in the R2 probe drain. LOCI® Results: Checks the performance of the LOCI® module Mean and SD are calculated from five consecutive absorbance readings for each of the five CHK aliquots aspirated. The Mean is compared to the carton value of CHK to assess accuracy. The SD is used to assess precision. When System Check results are printed: Record these results on the Daily Maintenance Log: Record Temperatures – Cuvette, Reagent, HM Check Empty Cuvette Waste Check Run System Check Tip: Do not log temperature results that appear in parentheses. This indicates the system is acquiring the temperature. Refer to the Daily Maintenance Routines Screen for current temperature. Record these results on the Daily System Check Log: Photometer wavelength: Are all wavelengths OK?
