Introduction
Slight deviation in the static convergence can be
corrected by using two permanent pairs of magnets
which are fitted around the neck of the CRT. These
are the 4-pole magnet and the 6-pole magnet.
The 4-pole magnet move the outermost electron 6-pole Beam motion producced by the
beams (R and B) parallel in the opposite direction 6- pole convergence magnet

Setting
- Before the static convergence setting can be made, S N
S
the monitor must be switched on for 30 minutes.
- The focus setting must be made correctly.
- Signal: 640 * 480, 31.5 kHz/60 Hz mode.
- Set the tabs of the 4-pole magnet in the neutral
position. This is when the tabs are opposite one
another. In this position the magnets do not affect the
deflection of the R and B electron beams.
- Set the tabs of the 6-pole magnet in the neutral
position. This is when the tabs are opposite one
another. In this position the magnets do not affect the
deflection of the R, B, and G electron beams.
- First set the 4-pole magnet optimally.
- Then set the 6-pole magnet optimally.
- If the convergence is not now optimal, then adjust to
the optimal setting with the 4-pole magnet and then with
the 6- Pole magnet again.
- Set the tabs of the 6-pole magnet in the neutral
position. This is when the tabs are opposite one
another. In this position the magnets do not affect the
deflection of the R, B, and G electron beams.
- First set the 4-pole magnet optimally.
- Then set the 6-pole magnet optimally.
- If the convergence is not now optimal, then adjust to
the optimal setting with the 4-pole magnet and then
with the 6- pole magnet again.
