Length Units
Under the parameter conguration menu use p and q to highlight “Length Units.” Press Enter to select the desired units of
measurement (Figure 3-16). Press to exit.
Index of Refraction (IOR) Conguration
Because IOR is a key factor affecting the speed of laser transmission in optical ber, the IOR conguration has a direct impact
on the accuracy of measurement. In general, the IOR parameter is provided by the optical ber manufacturer, and it can be set to
the accuracy of four digits after the decimal point between 1.0 and 2.0.
Under the parameter conguration menu use p and q to highlight “IOR.” Press Enter to enter a value (Figure 3-17).
Press to exit.
Use t and u to adjust the position of the highlighted area. Use p and q to change the digits. After setting, press Enter to
conrm.
Scatter Coefcient Conguration
Scatter coefcient determines the value of backscatter power. This conguration affects the calculation of reection value.
Under the parameter conguration menu use p and q to highlight “Scat. Coef.” Press Enter to enter a value (Figure 3-18).
