... Sensitivity shift If the incident light is stable in either the object present or object absent state, by shifting the threshold level towards this state, stable sensing is possible even if the incident light is unstable in the other state. The setting level is the same as for limit sensitivity setting. However, since the operating level is shifted after the normal sensitivity setting, output operation is selectable ...
