Projector is an optical instrument that uses optical elements to enlarge the contour of the workpiece and project it onto the screen. It can be used to measure the profile of the transmitted light, but also can be used to measure the surface shape of the hole and observe the surface of the parts. The projector is especially suitable for measuring complex contour and small workpiece, such as watch parts, stamping parts, electronic components, templates, molds, threads, gears and forming tools, etc., high inspection efficiency, easy to use; Widely used in measuring room, production workshop, especially for instrument and watch industry conference occasions.

Testing standard

CE Certification Instructions for projectors:
Projectors belong to electrical and electronic equipment, to ensure that the products meet the European standards, the need to carry out LVD and EMC directive!
CE certification standard for projector:
Projector LVD part of the regulatory standard: EN6090 information technology equipment. Security. General requirements for testing include marking and instructions, low voltage testing, power line tension testing, insulation testing, current testing, safety point testing, etc.
The test items corresponding to EMC regulations and standards for projectors are as follows:
EN55022 is a Radiation Test.& Right Test
En61000-3-2 is a Harmonic Test.
En61000-3-3 is Flicker Test (Voltage fluctuation Test)
En61000-4-2 is ESD Test.
En61000-4-3 is RS Test (Radiation Anti-jamming Test)
En61000-4-4 is EFT Test (Fast Pulse Anti-jamming Test)
En61000-4-5 Surge Test
En61000-4-6 is CS Test (conduction anti-jamming Test)
En61000-4-8 PFMF Test (Power Frequency Magnetic Field Test)
En61000-4-11 is a DIP Test.
CE certification process for projector:
1. The project application shall be submitted under the supervision of the testing agency.
2. Document preparation -- The company shall prepare relevant documents according to the testing requirements.
3, product testing a company will be tested samples sent to the laboratory for testing.
4, preparation of the report certification engineer according to the qualified test data, preparation of the report.
5. Submit for review 1. The engineer will review the complete report.
6. Issue Certificate 1. Certificate will be issued after verification.
