Rebuilding an I-Mag 423 Cold Cathode Sensor includes Disassembling the 423 I-Mag Sensor, Cleaning the 423 I-Mag Sensor & Assembling the I-MAG Sensor. Tools required for Disassembling the 423 I-Mag Sensor includes clean tweezers; clean smooth-jaw, needle-nose pliers. Cleaning process Depending on the degree of contamination and application of the Sensor, the internal parts may be cleaned - either ultrasonically, with mild abrasives, or chemically. it is suggested that measure the resistance between the ion current feedthrough pin and the grid washer to verify that the leaf spring is in contact with the cathode. The measurement should indicate a short circuit between them. There should be an open circuit between the ion current feedthrough pin and both the high voltage feedthrough pin and sensor body. The I-Mag sensor is ready for installation. If it is not immediately installed, cover the flange with clean, vacuum grade aluminum foil and cap with a flange protector.
