For some reason (I suspect the garbage radio shack brand probes, i miss my Pomona ones) when my meter is on the 300MA range it interests too much resistance and causes problems with some drivers, in one case the driver over voltaged by just a little bit and killed the diode under test, i need to make something with less series resistance or buy good meter leads, laser diodes are very sensitive for over voltage in either bias
