|
|
Couple of questions:
1. What is the little black SW button near the center of the face plate for?
2. To ensure that the contrast adjustment pot is at 0.7 v should I turn the adjustment multi-turn pot screw counter-clock wise about 30 turns? Is there a way to check the contrast trim pot setting value?
Thanks

Ok but we want it to be left at 0.7 volts correct?
So to make sure contrast screw is set at 0.7 volts should we turn the contrast screw counter-clockwise about 30 turns?

As you adjust the gamma the output level will change. SO it is best to adjust the gamma then go back and check the output level and adjust it back to .7vpp. It does take some going back and forth but you need to do it to ensure you have .7vpp output at 100ire.
