or calibration. When this occurs, the ‘Cleaning’ and ‘Hard cleaning’ maintenance function are available to perform
additional system cleaning on demand.
The ‘Cleaning’ and ‘Hard cleaning’ software maintenance functions are also available to perform deeper cleaning of
the system tubing and pneumatic components.
If the blank measurements are still too high after the ‘Cleaning’ maintenance function, it will be necessary to perform
the ‘Hard cleaning’ maintenance function for a more in-depth, thorough system cleaning. Running several blank
measurements may be required after performing software maintenance cleaning functions to return blank values to
within specifications.
If blank measurements do not return to normal after the ‘Clean’ or ‘Hard clean’ software maintenance functions and
after running several blank measurements, please contact your Diatron certified service engineer for additional
assistance.
17.8.1 Daily Cleaning
The Shutdown function at the end of the daily routine will request that a sample vial with 2-3 ml of
Diatro•Hypocleaner CC reagent with no cap be placed into the sample rotor. The software shutdown function will
clean the tubing in the measurement system.
Rubber sample caps are not designed for multiple punctures. The Diatro•Hypocleaner CC
reagent will cause rubber vial caps to harden, releasing small particles that will clog the
analyzer. Always remove the rubber cap when performing daily cleaning.
After this operation, you can leave the ‘Abacus 5’ analyzer powered on for the rest of the day. It will automatically
enter a low power state if left unattended.
17.8.2 Cleaning the Measurement System
During normal operation, the ‘Abacus 5’ analyzer may report high values after a blank measurement. Repeating the
blank measurement will usually bring the blank values down to within specification. If the blank values remain too
high, it will be necessary to perform a cleaning maintenance function.
If the system consistently reports high blank values, the measuring chambers must be cleaned.
1. Remove the cap from a clean, dry empty sample tube. Fill the sample tube with 2 ml of deionized water and 1 ml
of Diatro•Hypocleaner CC reagent. Do not replace the cap onto the sample tube.
2. Insert the sample tube with Diatro•Hypocleaner CC reagent into the sample rotor.
3. Click or tap the ‘Cleaning’ button on the maintenance functions panel in the ‘Cleaning’ group.
4. Follow the on-screen instructions.
5. Run a blank measurement and ensure the blank measurement values return to acceptable levels. Re-run the
blank measurement a few times if necessary.
17.8.3 Extended Cleaning (Hard Cleaning)
If the blank values do not return to acceptable levels after performing the ‘Cleaning’ maintenance function, repeat
the above steps except for clicking or tapping the ‘Hard cleaning’ button in step 3 rather than the ‘Cleaning’ button.
This maintenance function will perform a longer, deep cleaning of the measurement system, buffers and chambers.
