RV904

Adjusting method:
1)

Rotate RV904, and adjust so that the bright/dark sections of
gray scale are displayed correctly. (The bright section should
be unsatisfactory till the cross hatch appears vague in the
monoscope circle. The dark section should be unsatisfactory
till the darkest section of the gray scale cannot be differentiate.)

“1-5-5. Horizontal Amplitude Adjustment” and “1-5-6. Vertical
Amplitude Adjustment” should be both satisfy the specified values.
If not, perform the adjustments from the beginning again. In this
case, perform “1-5-7. Brightness Adjustment” again.
Moreover, check the focus, and if it found to be vague, perform “1-
5-3. Focus Adjustment” and “1-5-4. Aberration Adjustment”.
