What is a Last Word indicator used for?

The horizontal-face dial test indicator has a hard, chrome-plated, steel ratchet contact point for taking precise measurements in machining, layout, and inspection work.

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.

How do you read test indicators?

As you press the indicator against the part surface, lock the indicator into place and begin to watch the reading on the dial while rotating the part. As you rotate the part, the pointer on the indicator will move when it detects runout or surface distortion.

What is a dial test indicator?

A dial test indicator, also known as a lever arm test indicator or finger indicator, has a smaller measuring range than a standard dial indicator. A test indicator measures the deflection of the arm, the probe does not retract but swings in an arc around its hinge point.

How do you read a .0001 indicator?

How to Read A 0.001 Dial Indicator

  1. multiply the total inner scale divisions to 0.1″ (for example, 2 divisions, then 2 x 0.1 = 0.2″)
  2. multiply the total outer scale divisions to 0.001″ (for example, 10 divisions, then 10 x 0.001″ = 0.01″)
  3. add those two values of inner scale and outer scale (0.2″ + 0.01″ = 0.21″)

What is the least count of dial test indicator?

0.01 mm
What is the Least count of Lever Dial Gauge(Test Indicator)? The least count of Test Indicator(Lever dial gauge) is 0.01 mm with a range of 0.80 mm or up to 2 mm. But some special type of lever dial gauge has the least count of 0.001mm with a range of 0 to 1 mm.

What are the major differences between dial test indicator and a regular dial indicator?

Test indicators enable only a single revolution of the pointer around the dial, and test indicator pointers always travel clockwise. The dials are balanced, meaning that the numbers keep ascending in both directions from zero.

What should I look for in a dial indicator?

Once the dial indicator is zeroed, you can take measurements by moving the target part through its range of travel. The dial indicator will show movement either positive and/or negative. Always be sure to read the dial face straight on for the most-accurate reading.
