Measuring 425mA on a KD 2280mA driver?
I'm wiring up an XML LED in a test configuration with KD 2280mA driver and I wanted to get an amperage reading before permanently wiring it together. I put one of my meters in-line with the positive lead to the LED and measured about 3.5ma on low (what I expected). But, when I switched to medium (supposed to be 35% of the max) I only read about 115mA. On high I read 425mA.
I thought maybe I had somehow knocked out part of this driver so I wired up a spare KD 3040mA driver. On high I read about 490mA in-line with the LED.
Still uncertain of the readings, I pulled out my spare meter and found almost exactly the same measurements.
I'm very confused and hesitant to finish up the wiring until I better understand what I'm seeing. Can anyone shed some light on this for me? I'm probably making some dumb mistake or observation. Any help would be appreciated.
