This measurement was not accurate enough to be a true parallelism measurement because it wasn't down to the .0001". What is a more accurate description of this measurement? Rotor Runout Nominal Thickness Thickness Variation Rewatch

## Step 1<br />The problem is asking for a term that describes a measurement that is not accurate enough to be considered a true parallelism measurement. The term 'parallelism' in this context refers to the precision of a measurement.<br /><br />## Step 2<br />The term 'Rotor Runout' refers to the deviation of a rotating object from perfect circular motion. This term does not context of the problem as it does not describe a measurement that is not accurate enough.<br /><br />## Step 3<br />The term 'Nominal Thickness' refers to the standard or expected thickness of an object. This term does not fit the context of the problem as it does not describe a measurement that is not accurate enough.<br /><br />## Step 4<br />The term 'Thickness Variation' refers to the deviation of the thickness of an object from the standard or expected thickness. This term fits the context of the problem as it describes a measurement that is not accurate enough.<br /><br />## Step 5<br />The term 'Rewatch' does not fit the context of the problem as it does not describe a measurement that is not accurate enough.
