Hey all

I'm using a Flexmod p3 driver to provide current to my laser diode but I cannot get it to even provide any output.


There was only one instance where I was able to set the 0Bias and Gain where it worked perfectly and could be driven by a PWM signal afterward. However, the next day it just stopped working again.

I followed the instructions provided in the manual but the fault LED stays on no matter what I do. I set the interlock to the V+ potential and have the output wired into a multimeter. I'm able to set the 0Bias setting with M+ shorted. When I connect M+ to V+ potential to adjust the gain, after 7 seconds the fault LED turns on, or sometimes after 7 seconds the DMM would read 'overload.'

Any advice is appreciated.

Thanks
