Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-response curve. 2. Iv classification code is marked on each packing bag. 3. The chromaticity coordinates (x, y) is derived from the 1931 CIE chromaticity diagram. 4. Caution in ESD: Static Electricity and surge damages the LED. It is recommend to use a wrist band or anti-electrostatic glove when handling the LED. All devices, equipment and machinery must be properly grounded. 5. Tester:CAS140B is for the chromaticity coordinates (x, y) and Iv. 6. The chromaticity coordinates (x, y) guarantee should be added ± 0.01 tolerance 7. Reverse voltage is only for IR test. It can not continue to operate at this situation.
