1. VA-036 use a stepping motor rotate the LED test then output the set forward current to measure the light intensity and the forward voltage.
2. The VA-036 itself is without input keyboard and display. It need to connect to a personal computer with RS232 interface wire.
3. VA-036 includes view angle test system software.
1. To read the forward voltage (VF) of LED tested. 2. To read the light intensity of LED tested. 3. To read the view angle of LED tested. 4. To draw view angle chart. 5. To draw intensity-angle chart. 6. To draw intensity-IF chart. 7. To draw VF-IF chart.
