3. Deflection Adjustment Procedure
VL (Vertical Linearity) Adjust so that the boundary line between upper and lower half is in accord with geometric horizontal center of the CPT. VA (Vertical Amplitude) Adjust so that the circle of a digital circle pattern may be located within the effective screen of the CPT. SC (Vertical "S" Correction) Adjust so that all distance between each horizontal lines are to be the same. VS (Vertical Shift) Adjust so that the horizontal center line of a digital circle pattern is in accord with geometric horizontal center of the CPT.

HS (Horizontal Shift) Adjust so that the vertical center line of a digital circle pattern is in accord with geometric vertical center of the CPT. Press the OK(V) button to memorize the data.
