What is the Scan Delay timer range?

• A. 0 to 60 seconds
• B. 5 to 60 seconds
• C. 15 to 120 seconds
• D. 10 to 180 seconds

Answer: (C)

The Scan Delay timer range determines how long the system waits between scans to let signals settle and measurements stabilize before the next check. A range of 15 to 120 seconds provides a balanced cadence: long enough for sensor signals and processing steps to stabilize for accurate readings, but short enough to keep the system reasonably responsive to changes. Shorter ranges (like 0 to 60 seconds) can produce noisier data due to insufficient settling, while longer, broader ranges (like 10 to 180 seconds) can slow detection of quicker changes. That’s why 15 to 120 seconds is the most appropriate design choice.
