I have a problem.
I purchased the PH3803T sleds to get the 405 nm diodes from them. I also got the rckstr driver and a test load, all from Modwerx.
Now I do not know what the problem is. I connect the driver to a voltage source to the +/- terminals. The LD+/LD- terminals go to the diode, but instead of the diode, I have the dummy load connected. In the dummy load, I am supposed to measure the voltage across a resistor, where 1mV should be 1 mA; and then change the pot in the driver to adjust for the current that will be given to the diode.
Well, the issue is that I am getting between 1.75 and 2.02 mV through the reistor, that is all the range I get from twisting the screw in the pot in the driver.
Can I get some help? I don't know what's wrong; I thought I'd be getting something like 100 mA/mV. Is the voltage I am using correct? Could it be a bad driver? HEEELP!
PS: I searched for something like this but found nothing... I think I am doing everything right.
