- Strong electromagnetic interference environment (near high-frequency welders and large inverters): Shielded cables and filters are recommended
- Frequent replacement of target materials without recalibration: Will cause increased measuring errors
- Included angle over 5° between probe and target surface: Affect measuring accuracy; vertical installation is suggested
- Thick insulating coating on target surface (＞0.1mm): Block eddy current penetration and lead to inaccurate measurement
- Humid environment without moisture-proof treatment: High protection level cannot prevent internal circuit damage from long-term immersion
