It is desirable to confirm the resistance value in steps 5 and 26. Because, when the terminal 10 of the electrofusion joint 1 and the terminal 20 of the controller 2 are connected, depending on the structure of the terminals 10 and 20, the line 2 and the line 24 may be earlier than the lines 23 and 24.
This is because there is a structure in which 5, 26 are connected.
