  1. Connect three 1.5 V dry cell batteries in a series.
  2. Connect the positive pole of the battery to auto leveling sensor terminal A, and the negative pole to terminal C, then apply voltage of 4.5 V between terminals A and C.
  3. Connect the tester as shown in the figure.
  4. Verify that the voltage fluctuates linearly in the 0.5 to 4.1 V range while the links are moved up and down slowly.
