    2. Check that the float moves smoothly between E and F.

    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance
      Tester Connection Condition Specified Condition
      1 - 2 Float level is F (upper) 3.0 to 5.0 Ω
      1 - 2 Float level is between F (upper) and E (lower) 3.0 to 111.0 Ω (Gradually changes)
      1 - 2 Float level is E (lower) 109.0 to 111.0 Ω
