We use the Dial Indicator to measure __ overall rotor thickness. parallelism issues. rotor thickness variations. rotor runout.

## Step 1<br />A Dial Indicator is a device used to measure small linear distances. It is often used in engineering to measure the overall rotor thickness, parallelism issues, rotor thickness variations, and rotor runout.<br /><br />## Step 2<br />The overall rotor thickness is the total thickness of the rotor, which can be measured using a Dial Indicator.<br /><br />## Step 3<br />Parallelism issues refer to the alignment of the rotor with the axis of rotation. A Dial Indicator can be used to measure any deviations from perfect parallelism.<br /><br />## Step 4<br />Rotor thickness variations refer to the changes in the thickness of the rotor at different points. A Dial Indicator can be used to measure these variations.<br /><br />## Step 5<br />Rotor runout refers to the deviation of the rotor from its ideal circular path. A Dial Indicator can be used to measure this deviation.
