a. Purity Jig
b. Helmhortz device
2. PREPARATION
a. Set the Helmhortz device to local magnetic field.
Horizontal : 0 ± 0.03 × 10-4T
b. Aging should have been performed over 60 minutes.
c. Receive the purity pattern (White pattern).
d. Picture menu : CONTRAST ... Max. BRIGHT ... Max.
e. Set V-CENTER to [4].
f.
Static convergence should have been roughly adjusted.
g. Connect DC current meter through FBT (pin 3) and adjust to [1200 ± 10%] µA.
3. ADJUSTMENT
a. Set both purity magnet´s knobs to top.
b. Adjust the purity so that the markers on monitor scope of purity jig become symmetrical in horizontal direction.
c. Only for stripe CRT, correct vertical centre by purity magnet too.
d. Set up deflection yoke so that the position of deflection yoke becomes [10 µm ± 5] forward on monitor scope at this time by
attention note to tile deflection yoke.
e. Repeat procedures (a) ~ (d).
f.
Tighten deflection yoke band.
g. Adjust beam landing by microscope. (Only for model change or check instruments)
