| Error Message | Likely Cause | Fix | | :--- | :--- | :--- | | | Laser warming up or interlocks open. | Wait 15 min. Check fluid levels. | | "Compensation failed: Singular matrix" | One single-stain tube has no signal. | Re-acquire that tube. Increase voltage. | | "Area scaling factor is off" | FSC-A/FSC-H doublet discrimination is non-linear. | Adjust FSC Area Scaling (slider in Cytometer window). | | "Events are off scale" | Voltage too high. | Reduce PMT voltage. Do not use "Scale" in analysis. |

This article explores the capabilities of FACSDiva, its role in the laboratory, and why it remains a cornerstone of clinical and research cytometry despite the evolving landscape of analysis tools.
