3) Take the X and Y axes readings through the two holes in the three-sided box in a
similar manner as the for the Z-axis and record the results. (NOTE: For the 50 mm
range crackmeter, model 4415-5, all three measurements are taken from the square
bar to the three-sided cube as shown in Figure 3.)
4) The ambient temperature should be recorded each time readings are taken. Large
changes in temperature could have an effect on the readings.
3.3.2 Taking Readings with a Depth Micrometer
1) To read the Z-axis, slide the tip of the depth micrometer through the hole in the
rectangular bar of the crack meter.
2) Press the base of the micrometer firmly against the surface of the square bar and then
adjust the depth of the micrometer until the tip is touching the surface of the three-
sided cube. Record the measured depth as the Z-axis reading.
3) Take the X and Y axes readings through the two holes in the three-sided box in a
similar manner as for the Z-axis and record the results. (NOTE: For the 50 mm range
crackmeter, model 4415-5, all three of the measurements are taken from the square
bar to the three-sided cube as shown in Figure 3.)
