Abnormal background display on the screen
An abnormal background error on the Mindray BC-2800 can be caused by several factors:
1. Dirty or Contaminated System – Cleaning tests should be performed to remove any buildup or debris.
2. Electrical Issues – Poor grounding or electrical noise can interfere with the system.
3. Reagent Problems – Ensure the use of genuine Lyse reagent.
4. Electrode Issues – A greenish color on the electrode inside the counting bath may indicate a soldering problem between the silver plate and the copper wire. Resoldering or replacing the bath may be necessary.
5. Faulty Tubing or Connections – Loose tubing connections can contribute to the error.
6. Startup Procedure Needed – Running the startup procedure by pressing [F3] at the Count screen may resolve the issue.
If the issue persists after these steps, contacting Mindray Customer Service or a distributor is recommended.

A/d interrupt abnormal
"A/D interrupt abnormal" on the Mindray BC-2800 indicates a problem with the analog-to-digital (A/D) interrupt function. This may suggest an issue with the system’s ability to properly convert analog signals to digital data, which could affect test accuracy. The test for this function is done by selecting “A/D interrupt” in the “Circuit” group. If the test result is not normal, service may be required.
