I have a question about the 10 turn potentiometers on the LCDPS and LCPBS power supplies. Do they have to be changed from default and if so how are they tested ? Sorry, newbie question.

You have to check and adjust the voltage output before you connect the PSU to the rest of the system. You will need a voltmeter/multimeter to do that. If the voltage is too high or too low, the units will not work properly and there might be damage to components.

I have another question regarding the adjustable pots' also. Can they get turned too far. If so, how does one get back into their range . I have one on the LCDPS supply, where I cannot get it to change very much, maybe 6.5 to 7.1 volts, I am sure I have turned it too far.

Yes, you can damage the pots by turning them excessively beyond their limits. Though I have gotten away with going a little beyond before.

When you feel the adjustment screw begin to resist stop turning.
