Upon the completion of any set of readings taken subsequent to the <br />baseline, of particular interest is the relative movement of the inclinometer <br />casing over time. To obtain this information, the baseline reading is <br />subtracted from each subsequent reading to yield a displacement relative <br />to the intial installation shape. Graphically, this provides a plot of <br />displacement of the inclinometer casing over its depth and over time, <br />shown in Figure 5 below. The "A" axis shows movement in the direction <br />of anticipated movement, while the "B" axis (not shown) shows <br />movement in the direction perpendicular to anticipated movement. <br />Figure 5. <br />For purposes of comparison, readings <br />subsequent to the baseline reading are <br />"normalized" by subtracting the baseline <br />deviations from horizontal from the <br />subsequent reading to arrive mathematically <br />at the total displacement of the latest reading <br />from the baseline reading. This is shown <br />graphically here, where the baseline reading <br />would plot as a perfectly straight and vertical <br />line. <br />PA M-6 L1 BH0535, A-AXIS <br />-1.00 -0.50 0.00 0.50 ILO <br />Cure.
