   Standard resistance:

     Tester Connection | Condition | Specified Condition
     A-1 - B-1 | 23 to 25°C (73 to 77°F) | 0.5 to 2.5 Ω
     A-2 - B-1 | 23 to 25°C (73 to 77°F) | 0.5 to 2.5 Ω
     A-2 - B-2 | 23 to 25°C (73 to 77°F) | 0.5 to 2.5 Ω
     A-3 - B-2 | 23 to 25°C (73 to 77°F) | 0.5 to 2.5 Ω

   If the result is not as specified, replace the heater assembly.
