I have 2 of my 4 LEDs wired and operational. They are my 12 blue plus 2 green on one driver and 12 royal blue + 2 green on the second. As both need to be less than 1300 ma I am trying to adjust the current. Had to get another meter as my current one only tested dc current, not ac. So I wired in the meter in between the first and second led. ( red wire from driver to first led+, - on led connected to red probe, black probe to - on second led and then positive to negative down the line....) I turned the nylon screw current adjuster all the way counter clockwise and have it wired to my boostled typhoon controller which is set to the all on mode at 100%. All 4 of my drivers are wired to my controller but only the 2 I am trying to dial in have completed circuits as I am waiting on replacement LEDs. I have only the one driver I am trying to dial in plugged into an outlet at the time of testing. Okay. So on both, when I power up at the lowest setting ( all the way counter clock wise) I get a reading of .0000. The lights do come on though. As I turn the screw I get some wacky numbers that go all over place initially but when they settle down I can never get them above .0021 for one and .0018 for the other, not the .90 that would indicate the 900ma that these LEDs are rated for. Now I can tell that as I turn the screw, the lights do get brighter but not the full duration of the clockwise turn. Only during a small duration of that turn. My meter is set to 10A and my red lead is in the AC port and my black is in the Com port as my meter instructs. So my question is am I doing something wrong? I can't get close to the right .9000 reading that I believe I need. I am afraid that at the .0021 that I actually may be over powering so I have tried to get it to .0009. On one of the drivers I can but the other it can't be adjust to that. It goes from .0000 to around .0012. After trying for 30 min I could not get the .0009. Or much of anything in between for that matter. Any thoughts?
