LS181 car solar film Tester One: Overview Test principle LS181 car solar film tester is the use of an ultraviolet light source, visible light and infrared light irradiation test transparent materials, sensors are detecting three light and incident light intensity through the test Intensity transparent substances, the transmitted light intensity and transmittance of the incident light intensity ratio is expressed as a percentage. Most of the solar film, visible light transmittance index mark, infrared and ultraviolet blocking rate index mark, blocking rate = 100% - transmittance. LS181 directly measure and display UV blocking rate, infrared and visible light transmittance blocking rate, easy reading and understanding. Two: LS181 parameter 1. Dimensions: Length 216mm × height 134mm × width 29mm 2. Test the tank size: width 47mm × depth 91 mm 3. Instrument Weight: about 590 g 4. Resolution: 0.1% 5. Accuracy: better than ± 2% (colorless homogeneous translucent material), manufactured using a standard template detection better than ± 1% 6. UV: peak wavelength of 365nm 7. Visible: the peak wavelength of 550nm 8. IR: peak wavelength of 950nm 9.5V AC / DC power supply, and optional mobile power (charging Po) powered three: LS181 structure description right is the side of the instrument marking text. ??? "OFF / ON" for the instrument switch "5VDC" as AC / DC power jack "USB" as a Micro USB seat, convenient mobile power supply to the instrument IV: Instrument Operating LS181 car solar film professional tester for testing the Sun UV-blocking of the film, an infrared blocking rate and visible light transmittance, measured as follows: 1: Plug in the power, keep the test tank is empty, open the tester's power switch, the version number is displayed first instrument and instrument type, the UV Rejection and infrared blocking rate window data is displayed as "0", the visible light transmittance window is 100. Indicates no measured object, the infrared and ultraviolet barrier is 0%, the visible light transmittance is 100%. 2: DUT (solar film, foil glass, etc.) into the test tank. Three digital tube display analyte UV blocking rate, infrared and visible light transmittance blocking rate. Five: Instrument features 1. UV blocking rate, infrared blocking rate, visible light transmittance meter (light meter) 2. triple parallel optical design, test data is not affected by sample test placement 3. For automotive film , explosion-proof film, construction film, insulation film, foil glass, the transmittance (blocking rate) real-time dynamic testing The instrument has self-calibration, automatic calibration 5. Simple operation after power, rapid, just to be tested was placed in a test tank, now also shows the results of the three tests applied to solar film 6. The performance display of the exhibition, production, quality control, inspection and other occasions 7. patented product, patent number: 201320406828.8 six: Use the steps and precautions 1. Instrument connected to a dedicated power supply, keep the test tank is empty, turn the machine off 2. The analyte into the test tank, as close as possible to the left analyte test slot 3. When not in use, turn off the power supply 4. Boot instrument self-test and self-calibration, test tank must be empty or can not complete the self-calibration 5. Avoid contact with corrosive materials, away from heat and humidity of the environment 6. When used continuously for a long time, since the luminous efficiency of the LED light source (LED light source temperature increases, efficiency decreases) reasons, may result in the three data windows can not be displayed as "0,0,100" in the absence of the test substance, then please turn off power to the instrument, re-POST and self-calibration, without affecting the measurement accuracy and proper use
