*1 It is definition with the center strength, 1/e2(13.5%) at the center of measuring. There is leakage light except for the specified spot size and in case of the objects with high reflectance around detecting distance, it may be affected.
*2 This value is for average numbers, 256 times(with exclusive amplifier) and white ceramic(when glass measuring for XHA-25KL)
*3 This is typical value at the center of measuring for average numbers, 256 times(with exclusive amplifier). It may be changed depending on the objects.
