need help how to measure CC

OK i recently post this on blue ray an violet laser....

but it was pretty complicated so since this is the driver forum some body might explain in simple words.

i explain my problem in the picture so if you could just save it an attach it on your comment to answer my question please do it. or to see the real multimeter that i have check the link below.
http://laserpointerforums.com/f38/help-again-please-about-driver-54993.html

cause i had the two point for the red solder together an i desolder them already now do i have to solder the blue together to check the current.

if i don't have to i been putting my positive cable on the left point an changing every symbol every number on the multimeter an no number shows up.
So thank you for ready all this an commenting to helping me.

:thanks:

If you want to measure blu ray solder a bridge where it says "BLU". and leave the red de bridge. "there must be gap".

Set your MM to either 200m or 2000m on the DCV side. For a PHR-803T just set it to 200m because you will get a more accurate reading because your not going over 200mA.

If you want to measure the current for a PHR803T LD then the
200m (200 mA) just above the 10A on your picture will be enough.
You will not drive the PHR803T to 200mA or it will surely blow.

A picture of YOUR actual meter would be much more helpful...

If you are measuring the Voltage Drop across a test load resistor
then use the 200m (200mV) on the Voltage scale as stated
above...

The 2nd picture is useless... it is like showing me 4 bricks of
a house and asking where to put the Door...
