hey

by shorting across the 200ohm resistor , I can get down to zero ( or anywere els below 9mA/90mA )

ther's somthing wrong with shorting it ?

BTW : I trent 24houres with current set to~ 902mA ,  here's pic of that trend -->





the whole sistem runs at +-1%  (resistor's fault )

another wierd thing is . when no DUT is connected , the set current reads lower by 13-15mV , when does connected , reads out by +-1% (fine )

does the curve represent relativly stable loop ? or thats not good ?

thank you in advance !

What we need is more pictures that are  way too large and way too blurry.

sorry , it's Sony Ericsson , only 2Mps ,I have no flukeview cable+softwear , so couldn't catch it better.

you can still reduce the image size

Sure but maybe use a service that looks less sketchy like imgur or something

Imgur or photobucket. Either one is fine.  Photobucket requires you to create an account; that can be a hassle if you don't already have one.

I prefer imgur. It's quick, anonymous, no need to make any account, and never seems to be overloaded.

that siz site you used first just seems to wait forever for me, I can't load any images from it.  I am in Canada.

you can also use attachments. 

Cheers!

hey

I have no time for busing with that , but I have aproach to new camera ,

is that's acceptible res ?

oh and the pic shoes the load run at 1A@16V ( 2 MOSFET's and 2X50mohm shunts )
