The Fluke SV225 stray voltage adapter solves the problem of stray voltage appearing in electrical installations due to the capacity between wires without compromising safety. Without the SV225, erroneous readings on high impedance meters may occur. With the SV225 on energized wires, the meter will indicate the real voltage, on non-energized circuits the meter will read close to zero (even if there are stray voltages). The SV225 can be used on all meters with standard input spacing.
