Horizontal Circuit
Adjustment
1. | POSITION adjustment
To adjust the horizontal position of waveform under
the normal sweep condition, proceed as follows:
With the T POSITION set to its mechanical center
position, adjust V R 2 0 6 (POS A D J ) so that the
waveform starts at the left end of the scale.
2. X POSITION adjustment
To adjust the horizontal position of the waveform
when the S W E E P TIME/DIV is in the X - Y position,
perform the same adjustment and then adjust V R 2 0 5
so that the bright spot comes to the center of the
scale.
