Using the Crack Width Gauge

Selecting a location where the edges of the crack are reasonably straight and parallel, hold the Crack Width Gauge in contact with the crack (at right angles to the crack).

Align the Crack Width Gauge where the calibration and the crack are the same width. Record the width, length and location of the crack.
