TDLS8000 High Drift / Unstable Reading - Decision Tree
Step-by-step diagnosis to resolve high drift alarms:
- Inspect sensor/laser for contamination or aging
- Good → Next step
- Dirty/worn → Clean or replace
- Check measurement path stability
- Stable → Next step
- Unstable → Stabilize path
- Verify laser output stability
- Stable → Next step
- Fluctuating → Repair/replace laser
- Check electronics module
- Functional → Alarm should clear
- Faulty → Replace electronics module
