Hi again,
I have the $41 dollar model from Dr. F/S , should be the same as any though. When I look through the eye piece I will sometimes see a very thin white line just a hair above the bottom of the blue area. I believe it is more noticeable when there is more water on the plate. Usually when I see it the blue doesn't have a crisp bottom edge. I am putting 3 or 4 drops on the plate to cover the entire plate , and sometimes gently press down on the clear plastic cover to disperse it evenly on the whole glass plate. The white line would make it read about .001-.002 higher than the bottom edge of the blue. Again the white line isn't always there, and my progressive bi-focals make it that much harder to read.
Any help on how to use this instrument will be useful, ie. Light source, amount of liquid, cleaning instructions, and common mistakes.
Thanks,
