Notes: 1) Be careful when installing the thru-beam type ber equipped with the expansion lens, as the beam envelope becomes narrow and alignment is difcult.
Especially when installing a ber with many cores (sharp bending bers and heat-resistant glass ber), please be sure to use it only after you have
adjusted it sufciently.
2) The ber cable length practically limits the sensing range to 3,500 mm 137.795 in long (FT-P81X, FT-H20W-M1 and FT-H20-M1: 1,600 mm 62.992 in).
3) The sensing ranges are the values for red LED type amplier. Please contact our ofce for details on sensing ranges for other types of ampliers.
4) The ber cable length for the FT-H30-M1V-S is 1 m 3.281 ft. The sensing ranges in U-LG and LONG modes take into account the length of the FT-J8
atmospheric side ber.
5) Refer to p.76~ for the ambient temperatures of bers to be used in combination.
