Accessories Operation Manual
*1. The response time is the rise time or fall time of the output signal to 10 to 90%.
*2. The ambient operating illumination is the illumination that changes the analog output +5% F.S. at 200 lx; it is not the
operational limit.
*3. An analog output of up to 6 V (or 24 mA) can be output. The output is 1 V (or 4 mA) when there is no incident UV light.
*4. F.S. stands for full scale. For a current output, full scale is 16 mA (4 to 20 mA). For a voltage output, full scale is 4 V
(1 to 5 V).
*5. Definition of the luminous energy integral: The physical unit of the luminous energy integral is energy (J: joules) and
this value is calculated by multiplying the UV intensity (mV) by the time of exposure (s), but it is dimensionless when
this sensor’s analog output value (V) is used for the UV intensity. The integral is measured with an 11 ms sampling
