Mine reads 60 with settings off the roll chart.
Using Settings from a chart I got off BAMA, (I think), it reads 90.
A and B settings the same. C is 43, U is 2-6, and D is 5
Switch 6 is in ( ) meaning it is for the gas test and 1-7 are normal for shorts.
I too used roll chart settings. So 60 seems normal.
Your alternate settings seem to show better what the tube is. New should read close to full scale I would think
