LD View Angle Tester
VAP-103
 
Basic function
  1. 1 Operation power supply: AC110V±10%, 60HZ
  2. 2 ForwardCurrent: The Tester is bipolar current source. LD casing can be grounded.
  3.               10.0 ~    400.0 mA,    resolution 0.1 mA,    accuracy ±(0.5%+0.1) mA
  4.               401 ~    3000 mA,    resolution 1 mA,    accuracy ±(0.5%+1) mA
  5. 3 View angel control: -720.0 ~ 720.0degree,  resolution 0.36 degree,  accuracy±0.18 degree
  6. 4 Forward voltage: 0.000 ~ 10.000 V ,    resolution 0.002 V,  accuracy ±(0.5%+0.010) V
  7. 5 Lighting intensity:   
  8.                    0.000 ~ 4.000 ,    resolution 0.001,    accuracy±(0.5%+0.002)
  9.               4.01 ~ 40.00 ,    resolution 0.01,    accuracy±(0.5%+0.02)
  10.               40.1 ~ 400.0 ,   resolution 0.1,    accuracy±(0.5%+0.2)
  11.               401 ~ 4000 ,    resolution 1,    accuracy±(0.5%+2)
  12. 6 RS232 capability: Operating commands and data logging between VAP-103& PC are via RS232 communication ports.
Remark:
  1. a. It is kelvin measurement, and it measures contact resistance before measurement. If contact resistance is higher than 2Ω, the measurement for this time is unvalid.
  2. b. VF ≦ 10.0V while open circuit, and VF ≦10.0V while 3000mA
  3. c.VAP-103 can read current of sensing lighting in PD. (Voltage of sensing lighting is transferred by sensing resistor)
  4. d. d.    Lighting intensity can be transferredas cd, mcd and mW etc. by calibrated formula.
  5. e. The accuracy of real lighting intensity is defined by accuracy of calibrated sample, characteristic of PD and calibrated method.
