Instrument ElectronicsThreshold• Irradiance level which causes the unit tostart measuring <strong>UV</strong>• Counts all <strong>UV</strong> past that point• Varies due to scale, electronicresponse, optics, design• Use right dynamic range (scale) ofinstrument40 mWTemperature• Unknowingly introduce variations toreadings based on the internaltemperature of the unit• As detector temperature raises, readingsmay drop• Try to maintain consistent conditions andavoid rapid, repeated, long duration highintensity runs• If it’s s too hot to touch – it’s s too hot tomeasure
