Figure 2-44 Waveform display interface of Program mode
5. Result
The auto test complete interface, as shown in Figure 2-45.
 Result list: Steps, Results and Remarks.
 Readback parameters: Including readback current, etc.
 Running step: Indicates the number of running steps.
 Clear: Remove all data in result list.
6. Storage
In the Program function interface, you can press “Save” to save the
parameters for Program mode to the internal or external memory, and
you can read and recall it if necessary by pressing “Recall”. The SDL
can save ten Program files.
LED Test Function
This function adds a break-over voltage setting to the conventional CR
mode. In short, the load acts like a diode. When the input voltage of the load is
greater than the diode break-over voltage, the load can simulate the working
principle of a diode and measures the drive current as in a real LED test.
Calculation method of Vd and Rd value:
 Vo: Working voltage of the load of an LED constant current source.
 Io: Working current of an LED constant source.
 Vd: Break-over voltage of the diode
