How to Measure?

Advanced Dynamic Range

Truck scales are designed to measure large heavy objects and do not work well for small packages. The dynamic scale is wrong. Radiometers are designed to balance the amount of light reaching the optical components with the output from the detector. Too much light can solarize and change the optical components; not enough can lead to a noisy detector signal. A single instrument cannot always cover every single UV irradiance level found in a graphics facility. Instruments designed for low intensity sources like exposure machines will not always work on high intensity sources used for curing coatings. Make sure the dynamic range of the instrument matches the irradiance levels of the system on which it will be used. Watch for signs that you are over ranging the instrument. Any questions, check with the instrument manufacturer.
