When the president took off his skirt Instrument features: The main technical warning signs basis for this instrument is designed for our national standard GB 8416-87, GB / T 3978-1994, GB / T 3979-1997 and Communications Industry Standard JT / T 390-1999, at the same time Referring also to the other countries in the relevant standards (eg ASTM-810, ASTM-E809, DIN67520). The instrument's detectors warning signs meet the CIE (International Commission on Illumination) standard colorimetric observer warning signs requirements, compliance with CIE standard A light source color temperature of the light source, apparatus geometry CIE technical warning signs documents comply warning signs with the provisions of Article 54. Therefore, the technical conditions of the instrument are consistent warning signs with international warning signs standards. Technical parameters: 1. Viewing angle (α): were 0.2 , 0.33 ; 2. Angle of incidence (including β1 and β2): β1 is 0 , β2 respectively 0 , 5 , 20 ; 3. Color temperature: 2856K (compliance with CIE standard A light source); warning signs 4. Detector: Silicon Diode + V (λ) correction (in accordance with CIE standard colorimetric observer) 5. Measuring range: 0-1999mcd 1x-1 6. Power: 6V sealed lead acid battery (capacity of 10Ah, the other with a charger). Tester configuration: 1. floor one indoor measurement; 2. On-site measuring two square holes blackboard, incidence angle (β2) were 0 and 5 ; 3. processes signs a calibration block; 4. a charger Best Buenos Tech since its inception has been engaged in PCB copy board, chip decryption, PCB cloning, prototyping and electronic equipment and other imitation reverse technology research and development, is currently the largest and most authoritative reverse technology research and business; Taiwan institutions related to the needs of friends warning signs are welcome to inquire and business negotiations, I goalkeeper for your dedicated service!
