3-2. CONVERGENCE
(1) Horizontal and Vertical Static Convergence
1. Receive DOT HATCH signal adjust [BRT], [PIX] to looks
easily.
2. Set V. STAT Mg, BMC Mg to standard condition.
3. Correct V. STAT Mg.
(Correct vertical lag of R, B-DOT around the center of CRT.)
(Fig.3-5)
4. Adjust BMC Mg.
(Make evenly horizontal lag of R, B-DOT toward G-DOT
around the center of CRT.)
5. Adjust H. STAT VR. (RV701)
(Adjust horizontal lag of R, B-DOT around the center of CRT.)
(Fig.3-5)
6. Have to tracking adjust V. STAT Mg, BMC Mg because DOT
moves influence each other.
(Correct vertical lag of R.G.B.-DOT.)
