OK, thát causes the confusion.
Setting latitude or setting elevation of a polar mount are two ways of talking about the very same thing.
The elevation needed for a polar mount is dependant on the site latitude: at a latitude of x degrees, the elevation should be 90-x degrees.
So if one mentions the one, the other is known directly; and vice versa.
In your case latitude 38.2* means elevation needed is (90-38.2=) 51.8*.
However the scale on the mount could give degrees latitude, or degrees elevation. Both ways are possible, but in principle identitical.
In your case, the scale mentions Latitude. So to set the correct elevation of the mount, you should set it to the correct number of degrees Latitude.
To set the elevation of 51.8* right, on the scale you should look for 38.2*. So a coarse value of 30*, and 8.2* with the fine-adjustment.
Your angle measuring instrument, however, seems to measure elevation angle (angle relevant to the horizontal), when used in the way you have shown in your pictures.
So on that instrument, you must strive towards values of 51.8*.
Does this make it clear?
