In HART, what does a health flag typically indicate?

• A. Device offline
• B. Potential issue requiring maintenance
• C. Calibrated successfully
• D. Healthy

Answer: (B)

In HART, a health flag is an indicator that the device’s diagnostics have detected a condition outside normal limits, signaling that maintenance or investigation may be needed. It’s a warning about health, not a confirmation that everything is fine or that the device is offline. The flag prompts you to review diagnostic data, check sensor drift, power and electronics status, and verify loop integrity, so you can schedule maintenance if needed. It isn’t a statement that calibration succeeded, and it isn’t simply confirming the device is healthy.
