5.1. Effect on radiometer accuracy
This section of the manual describes the additional inaccuracy introduced by the AMPBOX, in combination with a CMP pyranometer.
(Preset range of 0 to 1600 W/m² = 4 to 20 mA)
The total inaccuracy is the greater of the absolute and basic values.
The basic inaccuracy is < 1 W/m², temperature coefficient is < 0.1 W/m² / °C
The absolute inaccuracy is <0.05 %
(of span) , temperature coefficient is < 0.01% (of span) / °C
For a span of 1600 W/m² this results in an absolute inaccuracy of 0.8 W ±0.16 W/m² / °C
In practice this means that the inaccuracy of the AMPBOX is <1 W/m² (@ 22 °C)
The additional temperature coefficient is <0.16 W/m² / °C.
