True or False: A detector fails a sensitivity test when within 5% of its upper listed sensitivity range.

True or False: A detector fails a sensitivity test when within 5% of its upper listed sensitivity range.

• A. True
• B. False
• C. Not enough information
• D. Not applicable

Answer: (B)

Sensitivity testing checks that the detector’s response matches its published sensitivity within a defined tolerance. The key idea is how far the actual sensitivity can differ from the nominal (expected) value, not how close you are to the upper end of the published range. If the tolerance is, for example, ±5%, then a reading that is within 5% above or below the nominal value is still acceptable. Being within 5% of the upper limit simply means you’re near the high end of what’s published, but it doesn’t automatically constitute a failure. A failure would occur only if the measured sensitivity lies outside the allowed tolerance—too low or too high beyond what the spec permits.
