2)
measured on white ceramic sheet

3)
the response time depends on the reflectivity of the object
For objects with a reflectivity < 7% (OADM 20x2480/S14C), the response / release time is increased automatically
up to max. 2.8 ms.
*4)
Missed measurements up to 30 cycles will be suppressed. During this time the analog output stays on hold.
*5)
xx% of full scale measuring range / °C
* 6) maximum sunlight on a white measuring surface
