Hey, so I got my driver hooked up to a power source (2 10440 batteries) for a 405nm diode, and I got the test load hooked up (resistor to positive output and negative to first diode) and I don't know why there isn't a reading on my multimeter. (BTW which setting should I use? 2000m?) anyways, what am I doing wrong? Should I use less than 6 rectifier diodes? The driver outputs 4.6 volts.
