Abstract : A device for measuring unwanted electric and magnetic field induced voltages in remote measurement sensors. A test lead is encased within a magnetic shielding conduit and is electrically connected to a remote sensor. Another electrical lead, identical to the test lead and also encased within the magnetic shielding conduit, is terminated by a short circuit in the vicinity of the sensor. This electrical lead travels through the same environment as the test lead on its way to the measuring equipment. Electro-magnetic field interference along the path of this electrical lead is an indication of the electro magnetic field interference along the path of the test lead.
