Irradiation test

The voltage between the connections LUM and GND_Sens is
in direct proportion to the irradiation measured by the ET
sensor.
Measuring a voltage
1. Measure the voltage U
and GND_Sens.
2. Calculate the irradiation I
I = U x 560
RR irrad
U = 1.50 V

I = 1.50 x 560

I = 868 W/m²

3. Estimate whether the irradiation value is realistic (in this
example, I = 868 W/m

Irradiation values depend on the weather. The following table
provides an overview of the realistic irradiation values that
can be expected under different weather conditions:
