Question adjust the LED driver for M140

Hello, Please advice. How do I adjust the LED driver for M140? I have dummy loads with 6 diodes 1N4007 and 1ohm resistor. What I measured the voltage on the resistor? I tried to set 1V on the resistance and the diodes I appear 5,07 V is too much? When I set 0.950 V to 4.98 V diodes can be measured. I am afraid to connect M140 before it set up correctly. What are the correct settings? Thank You.

Well, you aren't actually looking to regulate voltage... You want to measure the CURRENT output of the driver. Laser diodes aren't voltage sensitive UNLESS it's too low.

I used the measurements as shown. Then reading in mV will be the same as the current in mA. What values would therefore be set?
