What does a high impedance meter indicate when measuring a stray voltage?
A high impedance meter presents virtually no load to the circuit under test. By design, this is the ideal situation, since you don’t want to have the meter loading the circuit and affecting the circuit measurements. However, in capacitive coupling situations, a high impedance meter measuring between ground or neutral to the unconnected cable will indicate some amount of voltage present. Typically this voltage reading may be as high as 50% of the energized voltage in the same proximity. Is this voltage real? Yes, it is, but it’s static voltage, containing no real energy or current flow. For users who need to determine whether a circuit or connection is energized or not this stray voltage reading presents a real source of confusion. Is the connection hot or not? The solution, the SV225 stray voltage adapter: The stray voltage adapter is a digital multimeter accessory that allows the DMM to measure circuits subject to stray or ghost voltages from adjacent energized wiring.
