Abstract
A Hall effect sensor is transported to and away from a conductor to vary the sensitivity range of the sensor to current flow in the conductor. The device comprises a bracket supported on the conductor which holds a jack screw. At the lower end of the jack screw is a sensor block which holds the Hall effect sensor. The sensor block translates in a slide guide of the bracket, but is prevented from rotating. At the upper end of the jack screw is a knob for rotating the jack screw. Rotating the jack screw causes the sensor block to slide closer or farther from the conductor, which varies its sensitivity in measuring a magnetic field generated by a current in the conductor.
