To use a tread depth gauge, follow the steps below. the hand or pointer is on the dial face. Measure the distance between the machined bearing cap surface to the bottom surface of the bore (the tool will visually display measured distances, so read the display indicator once the center probe of the tool makes contact with the bottom of the bore hole). The thimble is on a shaft that sticks up from the base. Step 2 Rotate the indicator's dial until the pointer aligns with the "0" marking on the dial face. Most of these tools This linear measuring tool is very easy to use. Reject the dial indicator if its readings are off by more than 1 increment over the first 2-1/3 revolutions of the dial.

Calculate: 1 mm – dial reading = ΔZ 4. Then, spin the bezel such that the zero point is once again aligned with the pointer. How depth is considered safe and how depth is considered as requiring very soon replacement. Also the direction of the graduations is reversed from that of a "normal" indicator. A Vernier gauge is a useful measurement device equipped with two scales, one fixed and one that slides. That said, here are some analog gages that might still serve a useful purpose. that occur as well as where the hand finally stops. Price $256.00. To use a tread depth gauge, follow the steps below. The measurement stick extends at the opposite/top end of the gauge according to the depth of the groove. You shouldn’t do the determination of depth using the jaws on the caliper unlike inside and outside measurements. The way of taking measurement of vernier depth gauge is same as vernier caliper has. Grainger's got your back. True measurement = dial reading x compensation value Examples If a 0.200mm measurement is indicated on the dial at various values of θ, the true measurements are: For θ=10˚, 0.200mm×.98=0.196mm The Starrett 643 Dial Depth Gage has a knife-edge base and a needle point contact which has been hardened and ground.
