4.3 Shading mechanism

The shading mechanism serves to obtain the dark (zero-offset) signal of the pyranometers and the

measurement chain. The shading mechanism blocks all light illuminated from the lamp.

4.4 Lamp mounting pillar

The lamppost serves to position the lamp at a certain height above the pyranometers. In view of the fact

that the packaging has to stay within certain limits, the lamppost consists of two parts. The lower part is

painted black in order to avoid reflections of the lamp.

4.5 Lamp housing

4.5.1 115VAC/60 Hz Calibration Facility

The 115 VAC / 60Hz calibration lamp is a PAR CDM luminaire, constructed of cast

aluminium with non-corroding hardware and fittings.

4.5.2 230VAC/50 Hz Calibration Facility

The 230 VAC / 50Hz calibration lamp is a medium-sized, high-grade, rotation-

symmetrical floodlight with a narrow beam.

4.6 Lamp bulb

The lamp serves to generate an input signal for comparing the pyranometer responses. The calibration of

the reference is usually done outdoors under sunlight. It should be noted that if the reference and test

pyranometers are of the same type, neither the spectrum nor the intensity of the calibration lamp need to

exactly simulate sunlight because both pyranometers will be affected similarly.
