Hi Guys I am having a few problems.
1. When I test any my batteries, I test, it is the voltage advertised then it starts to decrease towards zero. This became apparent when my 9v that was powering my laser was making the laser bright for a few seconds, then dimming down really dark.
2. When reading off my test load, my mV reading starts pretty high, then without touching anything, The mV goes down, it drops hundreds of mVs. Its really confusing why this happens and of course its impossible to set. This happened both when using the 9v and when using four AAAs in series (6v 6A)
I am thinking the second problem might have to do with my driver (its a $2.50 constant Current cheapie) but it also seems to be linked to the first problem.
Thanks a bunch.
