ADJUSTMENT OF CONVERGENCE
1. INSTRUMENT
a. Helmhortz device
2. PREPARATION
a. Set the Helmhortz device to local magnetic field.
Horizontal : 0 ± 0.03 × 10-4T
b. Receive the crosshatch pattern.
c.
Picture menu : DYNAMIC Normal and adjust BRIGHT DAC until gray portion of crosshatch.
d. Set DY to CRT not to tilt (up and down and left right).
3. ADJUSTMENT
a. Static Convergence Adjustment
a. Make sure that the magnets are positioned as shown as in Fig. 1.
b. Adjust the 4-pole magnets (Fig. 1) to align centre dots of R and B adjust 6-pole magnets to align centre dots to G.
c.
After adjustment, secure magnets with magnet lock of white lacquer.
•
Beams move with rotating when static magnet is turned. Rotational reduce of beams differs by angle of two
magnets. Therefore, repeat magnet adjustment several times so that all aligned completely.
b. YHC, YV, XV Adjustment (Fig. 2)
a. Adjust that static and Dynamic convergence is best with YHC VR, YV VR and XV coil. In case of static convergence
is tilted, repeat (1) Static Convergence Adjustment.
c.
Dynamic Convergence Adjustment
a. When dynamic convergence is bad, fixing permalloy between neck and DY so that dynamic convergence best.
Fig. 1
4. CONFIRM THAT LEFT UPPER SIDE LINE IS STRAIGHT.
When left upper side line is not straight, put magnet on DY and adjust the left upper side line to straight.
