About the Instrument’s Voltage Sensors Appx. 2 About the Instrument’s Voltage Sensors Each of the instrument’s voltage sensors incorporates an internal electrode (metal plate). When the voltage sensor is clipped around the measurement target (wire), the minuscule current I flows due to capacitive coupling between the measurement target and the voltage sensor’s internal electrode.
