For use with 69500 Series Reel Isotherms. Unroll the cable, open the wiper so that the old cable can slide through, remove the two screws at the end of the cable that are attached to the grounding position and the insulated post, and pull the old cable assembly out. Take the new cable assembly through the wiper system, attach the longer of the two wires to the insulated post and the shorter wire to the grounding position on the drum. Rewind the cable and re-calibrate the unit. For further information on calibrating the I-2000, please go to "Instructions" of this web site to watch a video on the calibration system using the 69550CAL tool.
