Length Units
Under the parameter conguration 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) Conguration
Because IOR is a key factor affecting the speed of laser transmission in optical ber, the IOR conguration 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 conguration 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
conrm.
Scatter Coefcient Conguration
Scatter coefcient determines the value of backscatter power. This conguration affects the calculation of reection value.
Under the parameter conguration menu use p and q to highlight “Scat. Coef.” Press Enter to enter a value (Figure 3-18).
