      (Spiral Cable with Sensor Sub-assembly)

      Measure the resistance between the terminals of the spiral cable with sensor sub-assembly according to the value(s) in the table below.


      1. After setting the spiral cable with sensor sub-assembly to the center position, rotate the spiral cable with sensor sub-assembly 2.5 times clockwise and measure the resistance. Then rotate the spiral cable with sensor sub-assembly 2.5 times counterclockwise and measure the resistance.

      2. After setting the spiral cable with sensor sub-assembly to the center position, rotate the spiral cable with sensor sub-assembly 2.5 times clockwise. Then while rotating the spiral cable with sensor sub-assembly 5 times counterclockwise, measure the resistance.

      Standard Resistance
      Tester Connection Condition Specified Condition
      z5-2 (SUP) - P19-8 (SUP) Always Below 3 Ω
      z5-4 (SDN) - P19-1 (SDN) Always Below 3 Ω
