Terminal No.	Standard
1 and 5	27⁺³_-2 Ω (when 20°C (68°F))

Connect the battery positive terminal to the terminal No. 5 and the battery negative terminal to the terminal No. 1. Plug the port (B) with your hand and check that air is not discharged from the port (C), when supplying air to (A).

NOTE: The purpose of this inspection is to check the valve movement, and it would be success if a large change of flow can be checked resulting from valve opening/closing. Therefore, it does not indicate a malfunction if a small amount of flow from the port (C) is detected when the valve is closed.
