Unlike the conventional models, the E3S-C scarcely has sensitivity variations between products. Therefore, you need to make the
above adjustment on only one diffuse reflective model of E3S-CD that will be used for detection under the same conditions, and
match the indicator points of the other diffuse reflective models of E3S-CD with the above adjusted one. (You need not match the
sensitivity of each sensor.)
