§ The sensor outputs (power signal) must have a resistance of approx. 500 Ω for a
correct measurement. Since the data logger has an internal load resistance of 70 Ω, we
recommend you to install a commonly available 430 Ω load resistor on the sensor
output.
§
Pyranometers can be used to measure irradiance either on the horizontal plane or on
the module plane.
