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

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      1 (HA1A) - 2 (+B)
      		20°C (68°F)
      		1.8 to 3.4 Ω
      1 (HA1A) - 4 (A1A-)
      		Always
      		10 kΩ or higher
