What is a Starrett dial indicator used for?
Dial indicators translate small linear distances into rotational movement to measure dimensions to 4.000″, with accuracies up to 0.0001″. They are typically fixed to a magnetic base or other Starrett fixture.
What is a precision dial indicator?

Adjust the dial indicator in such a manner that when the contact point of the spindle rests firmly on the comparator stand base, the hand registers 0.000. 10.5. 2.2 Record the zero reading on the dial indicator calibration form.
How do you calibrate a dial test indicator?
Detailed Procedure
- Using index finger, depress the IUT contact point slowly and evenly over the full range, slowly allow the contact point to return to its starting position.
- Securely position the attachment arm onto the indicator checker.
- Position the micrometer thimble and test indicator to obtain zero readings.
