How are the upper and lower thresholds configured?

• A. They are programmed together
• B. They are programmed separately
• C. They cannot be configured
• D. They are fixed

Answer: (B)

Upper and lower thresholds are set as separate programming parameters to define a guard band around the normal range. This separation lets you tailor the high limit and the low limit independently, so you can raise or lower one without changing the other and still maintain a meaningful detection window. If the thresholds were programmed together, adjusting the high limit would automatically shift the low limit, reducing flexibility and potentially increasing false alarms or missing true events. Saying they cannot be configured or that they are fixed isn’t accurate for most programmable systems, which are designed to allow individual adjustment of each threshold.
