Wait for the foam to go down. Mine usually don't take very long. Then,look at the 2 deg increments between the #'s. You see the 1.xxx,the 10,20,30,etc. Then,the lil lines are 2,4,6,etc. So,for example you see1.010 mark,the liquid line 2 marks below that. You'd read 1.014. Just makin sure that's clear.
And thanx for the correction calc. Easy to use!
