Notes:
1) Conditions which have not been specified are to be taken as: 24 V DC supply voltage, + 20 ℃ + 68 ℉ ambient temperature, SELECT gain setting, 300 ms response time setting, measurement center distance, interference prevention function not used and white ceramic board object.
2) This is the value at the measurement center distance, and is based on the definition of 1/e² (13.5 %) of the beam axis light intensity. Take care that some amount of light spreads out of the specified spot diameter and, depending on the conditions around the measured object, may affect the measurement accuracy.
3) This is the typical value at the measurement center distance for a white ceramic board object. The given values are for the analog output of the applicable controller.
4) This is the value for white ceramic board object. The linearity may differ depending on the measured object. The given value is for the analog output of the applicable controller.
