Detects
- Door-seal and hinge leakage at the 5 cm reference distance
Cannot detect
- Communications signals — single-band instruments are blind outside 2.45 GHz
- Compliance, in the regulatory sense: FDA compliance testing uses a specified load and probe
What to insist on
- Range covering at least 5 mW/cm² without saturating
- A spacer that fixes the 5 cm reference distance
