Thread: Dial indicator help

Small inner scale - each number is 0.1 of an inch
Outer scale - each division is 0.001”

Each full turn of the large pointer will move the small inner dial 1 division eg 1 to 2 or 2 to 3 etc, all the way to 9 to 0 which is the limit of 1.00”

Is the picture upside down?

If it’s the outer screw, it should lock the outer rotating ring/bezel that allows you to 0 (zero) the large pointer on the outer scale.

You are correct it looked different on my phone changed to 7 o'clock in OP for future reference.

Thanks for the explanation that makes sense now!
