Make the connections like in this picture



Then just read the mA and turn the pot until you get the value you need. Then replace the test load for the diode and there you have it

Default Re: Setting my driver??? help.

the only change I would make to the above drawing is:-

For setting the current for Blu-Ray LDs use 6 rectifier Diodes and for
setting the current for Red LDs use 4 rectifier diodes..

Set it to 200mV or 2volts...
each mV is equal to 1 mA on the DMM...
