Correct Incorrect Phantom voltage results from capacitive coupling, and applying a low impedance load discharges it to show the actual voltage.

How can phantom voltage detected by a high-impedance meter be eliminated?

  • Switching to resistance mode
  • Connecting a low impedance load across the circuit
  • Increasing the meter's range
  • Using a higher input impedance meter
