Fig.4 Mark the overlapping line between the folded end and the other end of the paper, mark A
point as shown.
Fig.5 Mark C point (A and C into 180° symmetric), extended C level again, determined to
point B, L = BC, L is transducer spacing in Menu 25.
Fig.6 Remove the positioning paper, prepare weld the ball valve bases on A and B point, note
that the center point of Ball Valve Base coincidences with the A, B points.
