Detects

  • Capacitive coupling from nearby energised wiring to the body
  • The effect of unplugging individual devices, one at a time
  • Whether a demand switch or shielded cable actually worked

Cannot detect

  • Magnetic fields
  • Radiofrequency fields
  • Anything comparable between homes unless the same grounding reference and protocol are used

What to insist on

  • Input impedance high enough not to load the measurement, typically ≥10 MΩ
  • A defined ground reference: protective earth or a dedicated ground rod, documented in the report
  • AC millivolt range with 1 mV resolution
