I bought 2 refractometers on amazon, they are ATC, my question is concerning the specific gravity, mine often reads on both from 1.024-1.027 I would like a gravity of 1.026,and sometimes they do land on it, why do they do this? I follow normal refractometer usage protocol: wipe, calibrate, rinse, test, wash, although I notice when I'm done measuring salt and rinse it off and re calibrate it, reads 30 or 38 instead of 35, and so I have to adjust it again and again after almost every test. I'm stumped
