I am using 3 similar op-amps (AD848JN) from Analog devices, tha name of the op-amps for clarification are Op-Amp #A,#B and #C.
The configuration used to check the output offset is that one shown in the schematics. I have also attached the Voltages at every pin of the Op-Amps.
The point is that I am having an output voltage different of 0 V. According to the datasheet, making use of a potentiometer between the PIN1 & PIN8 with the wiper in PIN4 (Vs-) I can reach barely the 0.0 V, however when I unplug the potentiometer the values come again to the previous ones.
Does anyone has a solution for that?
Thanks in advance.

I have a better explanation and detailed purpose in a post named Laser diode feeding DIY driver . Please if you have the time check it out. Thanks for the help and comments.
