Unmeasurable state refers to a state where the light receiving waveform of CMOS does not allow for correct calculation of measured values. The types of unmeasurable states are as shown below.
Page 105: Alarm Delay Count
4.7 Alarm Setting 4.7.1 Alarm Delay Count ■ Overview You will be notified of an alarm if an unmeasurable state is detected. This function allows you to delay the notification until the set sampling count is reached. While an alarm is being delayed, the last measured value is held.

4.9 1 point/2 points/3 points Teaching 4.9 1 point/2 points/3 points Teaching ■ Overview This method is used to set the HIGH set value and LOW set value using one or more sensing objects. ● When performing teaching, it is necessary to set a teaching type in advance. For details on setting the teaching type, refer to "4.4.4 Teaching Mode".
Page 120: Point Teaching
4.9 1 point/2 points/3 points Teaching 4.9.1 1 point Teaching ■ Overview This method is to perform teaching on sensing objects and set the value obtained by adding the tolerance to the teaching result as the HIGH set value and the value obtained by subtracting the tolerance from the teaching result as the LOW set value.
Page 121 4.9 1 point/2 points/3 points Teaching Press the<ENTER>key. Teaching will be executed. When teaching is completed, "Success" is displayed on the display section. Then, the newly set HIGH set value and LOW set value are displayed in sequence, and the display returns to the measurement display.
